June KOM Challenge

From the Vertical Thread started last month, I thought it would be fun to put a one month challenge out there. Damnpoor gave it name, and it's on.

I think it would be fun to post your weekly results so everyone can see how good we're doing.

Those in training for Death Ride, Shasta Century, or Santa Cruz Challenge should have some serious elevation numbers.

Remember...be safe on the descents and it's always a great day to ride.

btw I am very opposed to doing it as feet of climbing per mile, since I'm not gonna give up my (long, flat) bike commute just to have a better avg %

meh... I just don't keep track of this stuff.

Besides the accuracy of all of our measuring devices varies quite a bit.

+1. I had 10,500 feet climbing, while others had 9,200 feet ... too much variance there.

Yep, last year I kept climbing stats using 2 devices and 4 tracking methods. My totals for the year varied by a bunch:

Garmin Edge 305 Displayed Data - 575,185 ft
Garmin Training Center ---------- 558,432 ft
Motionbased -------------------- 644,730 ft
Specialized/VDO ---------------- 541,679 ft

The Garmin uses barometric pressure, generally the most reliable though still subject to variability. However, riding with people with other Garmin devices they seem to be pretty close to each other. GTC and Motion-based both use different smoothing techniques. Motionbased is notoriously way off. GTC is probably pretty close - it is going to take out small rises that get counted on the actual device. i use Ascent and GTC (for back-up only, otherwise it sucks). 6,564 versus 6,474 for my ride Sunday - only 1.5% difference.

Nothing wrong with the challenge - I mean there is no actual prize money involved right?

Welp.

Utilizing GTC, my climbing stats for the week ending 06.07.08
is 12,579'. Today's ride from Auburn to Dutch Flat contributed over
half of that.

I finally did a little climbing. 3 Diablo climbs on Saturday. My elevation stats are all over the place though. I have a Garmin Forerunner 305.

Training Center says 12559'
Motion Based (corrrected with MB gravity) says 13464'
Looking at the elevation profile, it looks more like 10000'.

I'm not really sure why the first two are so much higher. Motion based seems to add up every little roller, even if it's a foot. I think Training Center is pure GPS, which has a lot of error in the vertical coordinates.

I'm curious, at what point is a small climb considered worthy to include in your elevation gain? How do the barometric devices distinguish this?

For sites like motion based it probably depends upon the spatial resolution of the digital elevation model they are using. It's most likely 30 meter from USGS. Every time you pass on to a new cell on the grid, the elevation for that cell would be used.

At least that's how I think it works.

I have approximately 6000 feet of climbing so far for June. I don't have a altimeter on my computer, but I map my ride out on Bikely. Just wondering how accurate is Bikely? I did an out and back on Carquinez Scenic Drive yesterday and according to Bikely, it was total climb of 4300'. It sure felt like a lot less. Can anyone verify this?

There is also the issue of surrounding terrain elevation (USGS) versus road elevation. Out here in the west, where many of the roads were built with the help of dynamite and bulldozers, the accumulated difference can be considerable.

While I don't ride with my Edge 305 anymore. I've done the Sequoia (9,000 ft) & Sierra Century (12,000 ft) this month. That puts me unofficially at 21,000 ft so far. I'll probably be doing 3 or 4 more 8,000+ ft rides before the Death Ride. Not to mention some hill repeats on Montebello.

Motion based is just notoriously unreliable. I don't think any units do the correction in the unit itself. Barometric will just be more accurate. The smoothing all happens in the unit itself. I did 2 trips to the top of Diablo today, one from Southgate (Green valley School start) and one from North Gate (out to the traffic circle, plus the south ranger station to junction. My edge 305 showed about 8,150 ft., Ascent 7717 and GTC. 7700/

Not sure where you started, etc. but my route has the two climbs to the top at about 3,400 feet each.

I'm at 20,227 for the month, 194 miles.

And speaking of KOM - on my second climb to the summit of Diablo yesterday I had a guy blow by me going what I thought was damn fast. He looked like he was time trialing the climb, except he didn't seem to be straining too hard. Completely fresh on my fist climb I would have had 0.0 chance of staying on his wheel for any appreciable amount of time. We get to the top and I hear him talking to his friends that he did the climb in 50 minutes and if I heard right was targeting a 46 minute climb up Southgate. That is blazing fast and it was a pleasure to watch. If you were the guy in the Mapei jersey - hats off!

Does running elevation gain count? I ran 10miles yesterday, +1600ft.

Sure, the only thing worse than running is running uphill. Give me a double century over a half-marathon ANY DAY.

From my Sigma altimeter (pretty consistent with Polars, usually reads about 10% less than friends with Garmins), I had 23,450 feet this week and 40,117 for the month.

I'm a slacker compared to you guys. My only climbing has been the 3peat of Diablo, weekly mtb races with some climbing, and yesterday a 10 x Cantelow @ ~550' each. I have just one or two more days open for the rest of the month to get some more in before the Death Ride. Luckily, I am feeling pretty strong, and my new compact crack has arrived in the mail.

As of 6/17/08 - 22,300

I broke 30k on Saturday morning, I thought I was doing well. Looks like I've got a ways to go if I hope to come anywhere near what jonathan is doing

Yikes!

As of 06.21.08, only 40k for the month. I have a feeling jonathonb715 is going to come in with some serious footies!

OK, it's a good thing speed doesn't count!

I added 20,357 feet this week (Sierra Rd felt like that much by itself), bringing me up to 60,474 feet for the month. However, my big climbing weeks are kind of done for the month now - I'll probably put in another 10,000 or so this week and then taper time.....

3 Mt. D. summits, Mt Hamilton, Sierra Rd, Calaveras (the hard way) - it was a good week.
