Yes, peak speed, not sustained.

I don't know what my max is, I'd have to look back through a bunch of data. From the time I hit my highest peak power (1010W, yay ;)), I hit 33mph. Flat ground, no leadout. I know I hit about 37 in a flat sprint in an early season race last year but I had horrible position and only got 14th :p About 38mph in a mildly downhill (<1%) sprint in a "race simulation" on saturday and mid 30s in my tuesday lunchride sprint (34 last tuesday). I hit over 30 in pretty much any solo sprint workout I do, but I'm a crappy sprinter. Some guys can certainly wind it up to nearly 40 if they want to. I was going 39 on a teammate's wheel on a ride a few week's ago... but things are rarely absolutely dead flat, there was about a half percent downgrade.

About 55kph is my record. I guess that's about 33 or 34mph. I can only sustain that for 40-50 seconds.

all I was trying to figure out was how I can be so damn slow.... I ride thousands of miles a year and can't approx 40 mph... what gives...

One thing has nothing to do with the other

Yesterday I won a prime sprint. I was actually leading out our designated sprinter, but my lead out was fast enough he couldn't come around me. Last week the one prime I went for I got second by a wheel length.

Final sprint, I was 3rd, and 8th, in the 2 races, both, with pretty large fields and both ending in field sprints.

I did not go over 33.5 mph for any of those sprints.

When people who do not race, tell you they do high 30's solo, without a leadout, take it with a grain of salt.

Thank You!

On solo rides I hover in the low 30s or high 20s. I've hit 50 once or twice and thought I was going to collapse. The most intense however was with a tailwind on a slight downhill on my fixed gear I got up 46.5 doing about 140rpm. Of course these figures aren't bs - they are in kmh.:o:rolleyes:

Whatchu talkin bout willis?

I'm gunning for Cat2 this season and in a 10mi TT without aero equipment I'm a smidgen under 26mph. Going all out.

Are your flats all downhill? Are you riding a vespa?

What Merlin said.

blankgen 01-26-09 01:41 AM

33.7 on a street with lots of trees to block the crosswind. I suck at sprinting though. I'm like a train getting up to that speed, no explosive power whatsoever:(

It must be the efficient wheels

I don't have a speedometer, so I really couldn't say...

grolby 01-26-09 08:25 AM

Like Merlin, I'm a cat 4 with a decent but not great sprint for that category (though it's a killer sprint for a 123 lb pipsqueak). I can hit 30 mph still in the saddle (when in form, that is) and sprint to 32, maybe 34 mph solo. We're talking peak speed here, no more than a second or two. There are guys who can wind it up a lot higher than the low 30's by themselves, even in cat 4, but not many.

Are your flats all downhill? Are you riding a vespa?

And god forbid if someone who dosen't race is faster than a Cat guy.

Thanks. A good dose of reality here. Either that or some of the posters are TdF riders

That's just the point; he's not faster.

bikeM3987 01-26-09 08:43 AM

I don't know my max speed, but I know I can hit 35 from a stop or a roll. Last year one of the sprint drills I did with my coach was multiple 0-35mph sprints in my 53-15 for cadence work. That being said, sprinting is all I am good at. I hate all you Cancellara types.

Looks like around 32mph from analysis of my power files from training rides.

What part of this is hard for you?

If you are not a pro I think you need to calibrate your computer.

waterrockets 01-26-09 09:27 AM

My best sprints in the last couple years have been about 37mph on flat ground with no wind sprinting in both directions. In Colorado, in my younger days, I hit 40 a couple times, but the air is much thinner than here in Austin...

I won a really big crit, solo for the last 30 seconds at 31mph, with a max speed of 32.6mph. If the pack takes enough of a beat down during the race, it doesn't take 40mph to win :)

What is the point of copying my post and just changing the numbers?
