If You Rode For 24 Hours..

how far could you go?

just wondering what the ranges are out there.. seems like the record is somewhere around 500 mi (for an upright bike anyway). but most of us aren't dedicated LD riders, just recreational types or randonneurs, so i suspect we'll be a bit lower than that.

the most i've done in 24 hours is about 430k, which really isn't that far. (267 mi) it was a slow ride over mountains with a lot of stops and headwinds. made for a helluva day tho! next year i'm shooting for 500k in 24 hours, i think it should be doable even by a mortal like me. 600k in 24 hours might be

anyway, how far could you go in 24 hours? (that is, assuming you want to ride for that long)

I've never really tried a proper 24hr, such as a fleche. I've done somewhere around 410 in under 20.

My best 600 (on a hilly course) is 35ish. 24 hours for a 600 would be very good -- in the "Bonner League."

600 in 24 hours isn't that hard, though it does require a certain focus on keeping moving. I did it in 2002 (Mersey Roads Time Trial) and I've only got under 70 hours for a 1200 once.

Amen to that. A couple years ago, 3 riders went sub-24 (by a few minutes) on the Oregon Randonneurs 600k. But that was 3 mutants, in near-ideal conditions, and a moderately easy course. Of course, no sleep stop.

Personally, I've done a fairly flat 400k in 18:30, but I was in excellent shape, riding hard, with a very compatible, aggressive group. We rolled thru St Paul, OR (maybe 15 mi from the finish) at 1am doing 20+ mph. One of the high points of my rando "career" thus far. And on the RM1200 this year, I covered the first 445km (Kamloops-Jasper) in 22 hrs. So, 500k in 24 hours would be within reach, but beyond that would be more of a stretch than I'd want to take on.

It really comes down to whether you're looking at a "semi-enjoyable rando" effort, or a "balls-out ultra racer" type of effort.

I'll be pleased with myself if I'm around 24hrs for the 3-Passes 400km.

If it was a dead-flat track and optimal conditions (like the century ride at the Indianapolis Speedway), I think I could do a triple century; but that's pure speculation based on my performance at this year's STP, which is a low-rolling double with around 3000' total gain. I rolled across the line in 14h 45m total time for that one, so I'm just extrapolating to figure that I could have churned out another 100 miles in 9 more hours.

If you look at the Montreal 24 hour inline skating event (http://www.inline24.com/results.php)..the winner did 544K or 338 miles. Seems like that could be doubled on a bike.

I don't see it being doubled (on a road course w/o autopacing) any time soon. I'm not sure about other records, but in 2007 a local guy (Chris Ragsdale) did a 24hr distance of 502.7 miles. I've seen some insane distances for 24hr records, but they were for things like autopaced track records.

I believe the unfaired 24 hour recumbent record is 516.5 miles or 831.23 km. James Kern did that at Sebring in 2006 , source here. This is a non-drafting event.

Whoops, Dennis Grelk beat that in 2007 with a course record of 522 miles.

I did the Boston Brevet Series 400k in about 24 hours. It was hilly! I'm hoping to do better next year.

Indeed. My approach is almost always the former. I like to enjoy the view.

That was a good time to Jasper. Did I get a photo of you on the B-J Highway or at Lake Louise?

Amongst the Brits, Roy Cromack did 507 miles in 1969. Andy Wilkinson did 525.07 miles in 1997. I think that is still the longest non-drafting 24 hr effort. http://www.cyclingtimetrials.org.uk/...?Cat1=1&Cat2=7

Something else to consider: Not all routes are created equal. Of course, I'm thinking in terms of the routes I ride most frequently -- here on Vancouver Island. Our traditional spring 300 includes over 3500 metres (11,500 ft.) of elevation gain; our summer 300 (Tsunami) over 3900 m (13,000 ft.). Our summer (Backroad) 400 over 4,000 m.

The spring 600 (Pacific Rim) that traverses the Island to Tofino and back, then up and down to Campbell River, climbs over 4600 m (15,000 ft.). Ken Bonner has managed a sub 24 on that with a partner of equal prowess. This year, I created the "Northward Ho" 600 route that travelled to the northern terminus of Hwy #1, at Port Hardy. The classic Island "End to End" AKA "Tortoise & Hare" 1,000 from Victoria-Port Hardy-Victoria includes the same amount of climbing as Paris-Brest-Paris. Good training on a PBP year.

Bonner's Ultimate Island Explorer 2000 route, this year, climbed a mind-boggling, quad-busting 20,900 m (68,570 ft.) He did this as a permanent in October, in 140:31

Yes VI is a lumpy place

check out some heavy weight stuff at http://www.ragsdaleridesagain.com/ Chris is a member of SIR who rode 502 miles and I believe beat that this past spring in Michigan. I'd be glad to ride 300 in 24 hours with moderate mountains.

Again, keep in mind there is a world of difference between fully-supported RAAM-type events and brevets.

I agree completely. What's the point of going on a ride like that if it isn't at least somewhat fun?

At the RM1200, the 10pm group was just flying out of Kamloops. IIRC, we got to the first control 1/2hr after it opened. After that things settled down quite a bit. But a quick start always helps the average speed.

In the "official" collection, there are two pics of me on the bike: one at Moose Lake, and one on the Bow Parkway. I'm the tall guy in a blue and yellow jersey on a recumbent. My fave tho' is me sound asleep in a chair by the fireplace at the Curling Club after the finish.

indeed, and i'm more concerned with unsupported 24-hour rides in this thread.

there's nothing wrong with supported LD, but it's hard to compare it with brevets or general unsupported riding.

Ah, I think I missed you on the B-J, but I believe I have you leaving Kamloops, at the start (last photo but one in the Kamloops gallery) at Velopix.

Many distances mentioned here are downright frightening.

This bent-riding refugee from 50+ would, if necessary to keep kittens being killed, maybe make a couple hundred miles in good weather without any challenging elevation changes. Move the kittens to safety, add some hills or weather problems and a hundred is about it.

nice.. no extra 2 miles for a rounded out 300? although maybe that's a dumb question.. sounds like a helluva ride! and pretty speedy too.

The ride organizer considered it 300, that was good enough for me even though my speedo said 298.

Boston 400k in '06 in 21:36 (~250 miles + a few bonus miles)
Boston 600k (DNF) in '06 - (~221 miles in about 17 hours)

The 600k crossed the Green Mountains in VT and had plenty of steep rollers in Western MA. Temps climbed to 90 or so going over the Greens.

The 400k rambled through Western MA with plenty of choppy pavement and steep climbs, including 2 long climbs near the mid point that nearly did me in.


So, no, I'm not a speed demon - and I have to add a few more hours to my ride times to hit the 24 hour mark.

But - bring on the Endless Mountains 1240k next September... I'm registered and planning a strategy to enjoy the ride as much as possible. That should be a good metric for 24h of riding.

The one triple century I've ridden took a tad over 21 hours and that was enough for me, at the time.

May try a triple again on Grand Tour (Malibu, CA) one of these years, then may ride the whole 24 hours just to see how far I can go. More likely, of course, if I have support.
