Texas - Jogger Seriously Hurt on Katy Trail

Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
IMHO, the jogger is at fault for wearing headphones and not having the situational awareness to know the cyclist was there...

DALLAS - A woman who was out jogging on the Katy Trail Thursday evening was seriously hurt when a bicyclist hit her.
According to police reports, 28-year-old Lauren Huddleston of Dallas abruptly turned left just as a woman on a bicycle tried to pass her.
Witnesses told police Huddleston had been wearing headphones and likely didn't hear the bicyclist.
The two collided near Cedar Springs Road and Turtle Creek Boulevard.
Both women were taken to a local hospital.
The biker's injuries were not life threatening, but Huddleston suffered a severe head injury. She is in the intensive care unit and may not survive.

I'm glad you brought this story to the forum. I saw the story on TV last night. I was quite upset that the news story suggest the cyclist on the trail as the problem and the cause of the accident. What is it about the public that see cyclist (not "bikers") as the problem? Cars don't want us on the roads. Pedestrians don't want us on the trials/side-walks.
If someone hears anything more about any follow-up actions or movements against the cyclist, please post becuase I would love to show up and support cyclist.
My thoughts and prayers are with the young lady and I hope she makes a full recovery.

That trail is great for getting from one place to another, but people ride their bikes up and down the thing way too fast for the traffic volume. As far as I'm concerned, it's just too short for a bike workout, but I have a feeling that's what happened in this case. The jogger wearing headphones is much more a problem than the fast cyclist, I still firmly believe. A MUP is exactly that... Multi-User.

I rode the Katy for the first time the other day, and I would never feel comfortable going that fast on a trail that busy. That being said, mothers who aren't paying attention on a trail with as much traffic as the Katy are being foolish.

Very sad, i hope the jogger survives and cyclist recovers
I hope this is a wake up call for dallas and the designers of MUPs and other trails intended for walkers, runners, strollers, dogs, kids, and cyclists...these trails need to be designed better and people need to be educated on how to use them safely...the trails claim to be designed for cyclists but what they are really designed for are bikers on a mountain bike, cruiser, or huffy's going 5-8 mph
i'm a cyclist and a runner and will never use a MUP on my road bike because it is just plain too dangerous for me, i don't think non-cyclists realize we are clipped into our bike, our tires have no grip, and our bike is narrow making them very different than the huffy's when we were kids...as a runner i always look over my shoulder before turning on/off a path and i choose to run on the soft trails (dirt, grass, tar, etc.) alongside the hard trails (concrete) that cyclists use...it's better for the joints and safer
i think the key is max speeds on MUPs, safety education (the trail has a pedestrian only path but few peds actually use it), and better road legislation for cyclists, we want to bike on roads, the problem is they are damaged, unsafe, and legally we are not treated as equals to motorists...if dallas is going to transform into the cycling hub it claims it wants to be, a lot needs to change and be geared towards cyclists going 15-25 mph not 5-8mph
The jogger died earlier this evening

Ooh... that's awful.
In general, and we apply this all the time to cars when they are the faster vehicles out on the road, the overtaking vehicle is primarily responsible for passing safely; also pedestrians have the primary right of way. Basically, even if the pedestrian did something erratic, I think it was in large measure the fault of the cyclist from the description given.
I feel terrible for the family of the jogger, and also for the cyclist who will now have to face likely legal action and deal with the guilt of contributing to (perhaps directly causing) the death of another. A sad story all around. :(
EDIT: On watching the video in the link, it was a very even-handed report, stressing that both cyclists and pedestrians are responsible for safety. Well done, Fox 4.

I'm sorry she's dead, but she shouldn't have been wearing headphones. If she had been more alert and aware of her surroundings, she'd still be alive.
So many times on our MUP I will ring my bell and even shout, and pedestrians will continue ambling two and three abreast completely oblivious of what is going on around them.
(BTW, I thought that that Katy Trail was in Missouri, not Texas.)

Clearly the pedestrian contributed to this, but the cyclist was riding to fast for the conditions.
If the rider had been going at an appropriate speed for the conditions, the accident would unlikely have been fatal, even if the congested conditions required the cyclist to pass close enough that the pedestrian turning around into the path of the cyclist caused a collision.
Whether anyone should be wearing headphones on a MUP is immaterial, the simple fact is that many (if not most users) of a MUP do wear them, and it isn't a road, traffic shouldn't be moving that fast.

...but the cyclist was riding to fast for the conditions.
Has anyone seen any mention of the speed of the cyclist? I haven't. I think the speed of the cyclist is irrelevant, the speed probably didn't add to the force of impact, it was just the fall and location of impact that caused the damage. People hitting their head from a stand still can cause death.
Just bad luck. It could have easily been another runner that caused her to fall and hit her head. Very unfortunate and sad. I'm glad however that the family isn't holding a grudge and instead is looking to prevent future similar accidents on dallas trails.
If the family were to take the matter to civil court, and if I were to be on such a jury, then there's no way (based on the open source facts) I would ever hold the cyclist liable in any way (much less criminally liable).

I saw an interview of witnesses to the accident on local television (FOX 34?). The witness described the cyclists speed as reckless.
Curious, do you think a cars speed is irrelevant when it hits a cyclist?
I don't think there is any doubt that the cyclists speed was a contributing factor in the DEATH.

I read a comment at the bottom of one of the articles where a woman described the speed of cyclists on katy trail being between 30-40 mph :-s so i'm not sure how good of a judge peds are at eyeballing speeds, and reckless is very subjective. On Katy trail you are lucky if you can even get your speed up to 15 mph, it is virtually impossible during the evenings...and yes, technically everything can be a factor in death especially in this case, a major factor though who knows at least until the cyclists gps or computer data is pulled.

This is not just a pedestrian problem, I've seen cyclists (including very experienced cyclists) that do the same thing when riding on roads with cars that want to get past.
The Katy Trail is so-named from being built on the rail line of the MKT railroad, commonly known as the Katy. The route in Missouri is quite long, I think, the one here in Dallas is 4 miles or so, in a very urban area. There may be some other Katy Trails around as well.

"First of all, my prayers go out to Lauren's family. This was a tragic accident. And yes, it was an accident because neither party intended to cause a crash.
I was on the trail that evening and was passed by the cyclist who was riding with at least one other bike. That notified me when they passed me and my dog and the couple in front of me. We were all walking on the wrong (bike) side and I wondered why this wasn't more clearly marked. I was just behind Lauren and reached the site just a couple minutes after the accident. I spoke with the eye witnesses while Lauren was being helped by the other cyclist, and they all said the same thing, the bikes said they were passing and the young lady didn't hear them but at that exact moment turned without looking.
This was an accident, a terrible one. One that should bring some awareness and changes to hike/bike trails. But this was not the fault of the cyclist. When he passed me he was under control and cruising at a reasonable speed. Several bikes were going much faster and I noticed they were not as courteous.
For those making judgmental comments about either party, keep in mind that the witnesses on the scene, who were unbiased, all said exactly the same thing. Currently, bikes are allowed on the trails. This may change, but unless they do, bikes have every right to be there and runners as well as bikers should take every step they can to be safer. Running with headphones so loud you can't hear oncoming bikes announcing their presence may be more motivating/enjoyable, but it is too dangerous on the Katy trail to do that, and not turn your head to look before you turn."
I don't understand the Katy.
For some of the length there are two parallel paths, one signed for pedestrians only and the other signed for pedestrians and cyclists. The only two times I've ridden there, the majority of the pedestrians eschewed their exculsive track and were mixing it up with the bicycles on the shared path. I entertained some theories on why this would be, but nothing I came up with quite fit what I was observing. (The news story said the jogger who was killed was using the shared side of the path.)
I also didn't grasp the at-grade crossing @ Knox. It's signed for bicyclists to stop until traffic clears. I never discerned any pattern to who stopped and who continued through without breaking speed: northbound cyclists, east bound motorists, south bound cyclists, west bound motorists. The intersection seemed to be entirely controlled by a psychic force my aura couldn't reach. Like most mysterious things, it was fascinating to watch.

The Missouri, Kansas & Texas (MKT) Railroad, the "KATY" ran from St. Louis westward across Missouri, cuts through the SE corner of Kansas, then runs south through Oklahoma and the Indian Nations on down through Texas to Dallas and beyond. Not all of the old railroad bed has been converted to trails, the most famous being the long stretch through Missouri...
Anyone remember the opening scene from The Blues Brothers, with the old Robert Johnson tune, "She Caught the KATY"? Same railroad, same trail.

This is so unfortunate. I can't ride on MUP's here in Dallas, just too much stress, too much activity.
Sad, regardless of the at-fault person, or shared fault. I have been on group rides, that went along paved MUPs as part of the route, and found myself wanting to opt for the busy parallel public street, rather that deal with dog leashes and strollers, and whole families walking abreast, on the MUP. I see these paved trails as a place to ride at a virtual waking pace, not a way to move along efficiently. It does, of course, save my feet, with their problems caused by walking and running, that are mitigated by riding.

This is a tragic accident.
We must strive to be careful every time we are out running or cycling. Three months ago I headed out for a nice morning ride. I should have been gone about 1.5 hours, but I didn't make it home until I had spent 3 days in the hospital. I'm mostly recovered now but I may never recover 100%. Nevertheless it could have been worse. I've been riding almost 30 years and I always think I'm being careful. I'll have to be extra careful in the future.
Maybe so, but I suspect the cyclist would get tagged for some liability... at least in any civil trial in the US I've heard of...
I was just stating what I would do were I ever on such a jury with these particular facts...

This line disturbs me:
But some folks suggest a speed limit or a total ban on bicycles. (From the MSNBC article referenced above).
I can see a concerted effort to ban bikes on MUPs, I've already heard some people interviewed say
that bikes should not be allowed on the same trails as runners.
In the news article they say, "...was jogging on the trail when she turned into the path of a bicyclist." The radio news report reduced this to "...was struck and killed by a bicyclist."

What the foot traffic does not realize is that it really is a bike trail. It was built with government transportation funding for bicycles. That is the only reason it exists. The amenities like benches, water fountains and lighting are paid by private entities. What many want to do now is strip the user group responsible for building the thing! Pretty stupid if you ask me.
The Katy Trail is also being extended to the northeast which will eventually more than double the length. Currently it is only 3.5 miles long. It is being built in phases. I believe with 3 phases to go, two are unfunded. If bikes are censured from using the trail then the Katy Trail should be defunded. If the runner community thinks it is so awesome and powerful, then let them come up with the money to build the thing. The cyclists are tired of carrying the water for everyone else and being treated like crap.
Angela Hunt, the city councilwoman for this part of town is very friendly towards cycling. She should be considered a friend in this issue.
The problem is that if the anti-cycling people get a speed limit imposed, then it will spread city wide. Ruining other paths needed for faster commuting.
A speed limit won't help, or wouldn't help in this situation.
Getting hit by a bike at 10mph is still going to knock someone over,
and it wasn't the impact that killed her, it was the blow to the head when
she fell.
Knowing the rules of the road so to speak, i.e. when someone announces 'on you left' you
realize they're passing you. One witness said that the same rider passed him just before the
accident and clearly warned him that he was passing, can't fault the cyclist for this.
Not wearing headphones/ear buds etc. or having them cranked up so loud you can't hear
approaching riders also played into this accident.
Personally except for the access trail from Hillcrest Ave to White rock I try to
avoid MUPs they are unfortunately an accident waiting to happen.

I've heard the same thing, that katy trail was mainly for cyclists commuting to downtown and it ties into dallas' master plan of reducing road congestion and parking issues as the city grows. I do wonder if more cyclists used the trail and outnumbered runners would all the articles then state runner runs into cyclist? Or would the runners start using their side of the trail, the soft trail?...but seriously what's next white rock having bans and speed limits? how about a limit on how many luke's locker or run on training group members can run side by side, these groups take over the entire white rock trail every time they go running.

I entertained some theories on why this would be, but nothing I came up with quite fit what I was observing. (The news story said the jogger who was killed was using the shared side of the path.)
Living just a block from Katy trail, I commute to work via bicycle and I also have run (frequently) on Katy. I found that it is FAR safer as a runner on the shared path. I avoided the pedestrian path as often as I could due to head phones, dogs, cats, squirrels, kids, strollers, groups walking hand in hand, etc. The problem out here does defy all logic, because there is no logic. People are selfish and don't consider 'others' when making their plans to do whatever it is they are doing on the trail. Or, in other words, they plug in and forget about everything.
I would be very curious to see how many people have been run into and just bumped or scraped up and it wasn't reported. I suspect pedestrian/cycle/skater crashes happens almost daily and by a weird chance of (avoidable and unfortunate) coincidences this woman was killed.
.but seriously what's next white rock having bans and speed limits? how about a limit on how many luke's locker or run on training group members can run side by side, these groups take over the entire white rock trail every time they go running.
Having trained with Run-on, I know they teach their groups to share the road. They teach proper road etiquette, proper rules of the road and communicate very similar to what you'd expect from a group ride. For education reasons, you want their groups to be as large as possible. They teach their runners how to share and hold a line; they do far more good than the minor inconvenience of having to pass them on the trail causes.
I can't speak for Lukes or DRC group etiquette. While I am a DRC member, I have not trained or run with their groups. I did almost take out a group of DRC members on the road part of the WRL trail (east side) where cars, cyclists and runners all mix. They group just wandered out into the middle of the road where I really didn't have time to react. By some freak accident, no one was hit. I know the next week, the DRC groups were in 2x2 rows and very well organized and communicated very well. SOMEONE said something and I thank them for that!
As a cyclist. I am also a GDB member, Dorba Member and PACC member. All of these groups do teach their riders how to share. Again, 'clubs' aren't really the problem here but should likely be used as a tool for spreading the word to all groups.
To the guy on the yellow bike on Katy trail this morning. My apologies for yanking your ear bud out to correct you about improper passing on Katy. I would like to have off line (and civil) communication as to why I felt my actions were necessary. (and would like to hear yours)
My version before I get jumped:
Me on a large MTB with roaring tires, him on a road bike.
two pair of pedestrians.
two walking north, two walking south. One had a dog (though I don't recall which one, based on my lane position, I'd say north bound had a dog)
I announced on left to south bound people, they moved over a bit and waved. I slowed to(12-15mph) and began to pass.
At this point, a bicycle flies by me on my left. (between north bound walkers and myself on the center line)
I got frustrated, announced "on your right", didn't even get body language that he had passed that close. So, I assume he's ignoring me or plugged in. I speed up to find out. Roll up on him and still, he doesn't know I'm next to him. I reach over and pluck the left ear bud out and announce (Announce you're passing next time). After a short unpleasant exchange, I remind him a woman was killed by a bicycle last week and he should be more cautious. I continued my commute to work.
A bit extreme, yes. But I'm not sure what it's going to take to get people to pay attention to their own actions rather than blaming 'others'.

i just remember seeing a wall of runners coming at me while on my bike at white rock and me thinking what am i going to do...i've boycotted GDB because in my opinion they don't practice safe and legal riding techniques (rolling through stops, running reds, creeping halfway through reds...) and in my opinion illegal riding doesn't just break the law but sets back the entire cycling community, legislation, and fuels motorist anger, so instead i drive 45 minutes out of my way and ride by myself on a 20 mile road with a big shoulder and no stops...no more trails, no more joggers, and no more unsafe groups for me, one crash and i decided to have the inconvenience of safety...
commuters though have to work with what they're given so be careful!

imo, street laws should apply to trails. anyone on trail should be able to hear surroundings just as you would when you're driving. you should always be able to hear emergency vehicles even with your windows rolled up. turning/switching lanes? you should always look all directions before making a move just as you would when you're driving.
well hope the jogger has reached the better place by now.

Sorry you had a negative experience with these group rides. As a former board member, I know they do not teach these illegal activities and I've personally made announcements at the start of group rides on the importance of not blowing signs/lights ESPECIALLY when cars are present. I suppose if you ride in the city enough, stopping at signs/lights comes just as complacent on a bicycle as it does in a car; as does avoidance of hazards in the road. Have you tried off-road trail riding? I find it's far more therapeutic than riding alone on a shoulder. Hikers and cyclists both are quite friendly and one can find a single track trail pretty easily in the N. Texas area.
If you were riding at 4:30-7am around WRL on T, TH and Sunday, then it may have been a Run-On sponsored training run. If evening, it was DRC or another group. If you do encounter a group that doesn't yield, stop and talk to them, see who the coach is and who they work with. (be polite) and then report back to the store owners/managers.

they also pick and choose when, where and who gets to run the stop signs...i was on a superbowl sunday ride with gdb a few years ago...we had already blown through no less than 20 stop signs...well i somehow found myself at the front of the pack, so naturally i went through a stop sign....i was then yelled at (no exaggeration) for a few mins by the "ride leader" about the rules of the road and how it was a "stupid move" to do that....5 miles later, i had moved myself to the back of the pack, as the whole ride was blowing through stop signs in highland park (in sunday morning church traffic nonetheless). gotta love double standards! i'm in a gdb jersey, so i can do illegal ****!

Call it whatever you want, but in my opinion, a sidewalk is designed exactly for that...WALKING. I "take the lane" on the street (ride exactly in the middle)rather than hugging the shoulder, so MOST cars don't encroach on me...it's safer than any stupid sidewalk but you can never bee 100% immune from accidents. There was an excellent cycling awareness website that had some interesting facts about bicycling accidents...it said something like 85-90 % of cycling accidents happen at intersections, not on straightaways...I'll see if I can find the link....

Ii believe some of the funding was from the normal transportation sources used by Rails to trails, so no it was not bike specific funding.
Here is a clip from the wikipedia article which seems to indicate much of the funding was private:
By the early 1990s, Dallas residents, business people, and city and county officials proposed restoring the greenbelt along the railroad route and creating an urban park as part of the national Rails to Trails Conservancy program, established in 1986 and based in Washington, D.C.
(http://en.wikipedia.org/wiki/File:Turtlecreek0003.png)
Initial funding for the project came through Dallas County and state grants. The Friends of the Katy Trail, a nonprofit organization, was founded in 1997 to organize public and private support for development and maintenance of the Katy Trail. Their capital campaign has since raised $11 million from government sources and $12 million from private funding and land donations.
The Katy Trail is intended to provide an effective way of connecting the various city parks running from White Rock Lake (http://en.wikipedia.org/wiki/White_Rock_Lake) to the planned park system along the Trinity River (http://en.wikipedia.org/wiki/Trinity_River_%28Texas%29)—it runs alongside Reverchon Park (http://en.wikipedia.org/wiki/Reverchon_Park) and the park system along Turtle Creek (http://en.wikipedia.org/wiki/Turtle_Creek,_Dallas).

You'll still have to catch and ticket the people going too fast. Even then, say a 15mph speed limit is enough to kill or seriously injure someone if they land on their head the right way. How fast was this cyclist going? Does anyone have any ideas?
Lets play a math game. Formula: F = m Dv/Dt Where F = force, M=mass, Dv=delta velocity, Dt= delta time. A quick google search gives me .0455 as a unit conversion for pound-miles per hour per second.
Say, a 200lb cyclist (180+ bike) traveling at 15mph hits a jogger who is stopped. Lets say it takes .5 seconds to 'stop' motion completely, since the jogger will give a little when hit. That's 200*15/.5 *.0455= 273lbs of force applied instantly to someone's shoulders. I'm too lazy to calculate the falling velocity of the runner when they actually are accelerated from 0 to whatever speed when they hit. I suspect it's in the neighborhood of 200lbs of force directly to the head when they impact.
Given the impact is more along the lines of .2 seconds and not .5, that force will nearly triple.
Lets do something else: A runner doing speed work. 6min mile isn't too hard for someone 'fit'. I'm not much of a runner and can run a sub 6min mile. I weigh 190lbs dressed. Lets assume it takes .3 seconds for us to crash and stop.
so 190*10/.3=6333.3...(.0455) That's 288lbs of force. More force than my first example, and with the right bad circumstances, enough to kill someone.

Brad, its not that lowering the speed will reduce injury but rather reducing speed will give people more time to react and hopefully avoid an accident all together.

2, 5, 10 15mph per hour, it doesn't matter how fast your going, what matters is WHEN the obstacle turns into your path as to whether or not you can avoid them/it. Speed as nothing to do with it.
And as long as joggers can wear earphones that they they can't ear surrounding sounds through (i don't understand this one because I can hear through mine) and bikers don't give all the warning they are supposed to (I'm guilty of it to), accidents will always happen. And hey, because we are human, accidents will always happen.
I'm sorry about the tragedy for this women and her family but it was an accident, just like the 4yo girl in NY.

Traveling at 2 or 5 miles per hour is not as likely to cause serious injury. 10 is probably marginal. 15 and above are starting to be real risks.

I tend to agree with this. I am curious do you also feel this way when a car hits a cyclist? I'm asking because I do for the most part., unless the motorist (or cyclist) are doing something extraordinary to place others at risk. Something like excessive speeding, DUI, etc...

For the Katy trail, just prohibit headphones and earplugs.
I figured out many years ago that they would decrease safety and stopped wearing them.
For the Katy trail, just....
...require all users to wear helmets.
Here is a clip from the wikipedia article which seems to indicate much of the funding was private...
The DMN reported in an article on 10/31 that some funding did come from government transportation moneys and therefore bicycles could not legally be banned from the Katy.
