    What's your max speed?

    Level ground, clean road, minimal wind, no drafting, just you and the bike from a slow-rolling start ... how fast can you make the bike go, with a maximum sprint effort?

    When I was a kid, I could hit 42mph pretty routinely. These days, nowhere near that, maybe 35 on a good day.

    I have sprinted at 40 for short distances but I can also hold 30 for quite a while.

    Level ground and minimal wind. What's that like?

    You realize that pros have trouble hitting that "routinely". Not to mention that they hit those speeds indoors on the track where there is truly no wind. The record is around 46 mph for the 200m flying start. So I doubt you came even close to that.

    Actually the record is at 47mph. Pro cyclists on the road regularly sprint at over 45mph with a leadout train, so assuming creaky was talking about drafted sprint it's very possible. 42mph for an undrafted sprint would be really impressive though.

    Personally max sprint with no drafting would probably be consistently at around 36-38mph. I hit 40mph once and I've never managed to do it again.

    Are you guys serious? Not you serious, you are obviously serious. Seriously.

    I never paid really close attention but if I remember correctly my top speeds were like 28 mph. I must really suck at this.

    If it makes you feel better whenever the gradient starts hitting 2-3% and the clever mountain goats start picking up the pace I get insta-dropped.

    Well, based on my iBike I hit 39.6mph, that was for a brief 12 seconds.... but I tend to top off between 30-35, cruise at about 16-20 on flats. Uphill it varies between 10-18mph depending on the gradient, and how tired I feel.

    I can see 42-45mph if you're drafting in a line being possible. Oh, and I run a compact with a 12-28 rear cogset. I want to run an 11-26, and see if losing the one tooth helps me crank out a bit more speed.

    Regardless, you're only going to go as fast as your legs let you. The strength of the engine in this case is relative to its ability to accelerate to X speed.

    I can do a 12 second flying 200, which is somewhere between 35 and 40 on my road bike.

    My max speed is 34 mph. But that is on a downhill. I can get to 22-23 on what seems like flat level ground. However I don't really have any flat level ground on my rides. Everything is slightly up/down or a moderate climb. I can average 20 mph for and hour+. This no draft on mix terrain and different wind conditions. I don't really ever "sprint", but I do try to ride hard for the duration.

    I just I am just not the sprinter type.

    It takes about 1400 watts for a 150 pounder to hit 42 mph. If it takes you 10 seconds to accelerate to 42 and then you hold that speed for 5 seconds you're maintaining 1400+ watts for 15 seconds. That's pretty impressive.

    My sprint sucks. My 15 second power is probably 700 watts which is about 30 mph which explains why I get destroyed when a race ends in a field sprint.

    My goal for my winter training is to improve my 5 - 30 second power.

    I have no idea what my non-leadout sprint is under these conditions. I have hit 38.something mph once. My maximum recorded wattage is 1260 watts. I weight between 153 lbs and 160 lbs when I race (depending on time of year). I guess someone could do the math to figure out what I "could" do based on my wattage and weight.

    I consistently hit 30-35 mph in various sprints, at least that is what my Garmin tells me.

    I'm truly impressed with the 40+ mph efforts. I have only hit 40+ mph on a steep descent.

    I'm 160-165 and can hit ~1200W. Used to hit 1310W a few years ago, but now I'm getting old. Currently doing a lot of olympic lifts (powercleans, deadlifts, etc.) and some plyometric stuff (in cross fit class), so I'm curious how that will translate to sprint power.

    So probably 35-36 mph, I imagine. But I still don't compare to you 40+ mph world class pros, LOL.

    In a sprint, they say the "jump" is most important, since after that initial gap is made, not much changes on way to finish line. There's still some luck.

    I haven't done well in finishing sprints (a few third places in our local B crits) but have won a lot of preems. Usually the second preem towards the end of the crit (that no one wants).

    Keep in mind there is a huge difference between hitting 1200 watts and averaging 1200 watts over a full 15+ seconds.

    I've hit 1100 watts momentarily before but I can only maintain maybe 700 watts for 15 seconds.

    Yes, somewhere in there. 37.28, to be more precise.

    That was my first thought when I started reading some of these numbers. Meh.

    Poweragent said I hit 725W for 30s on April 10th, 2012. Probably for most individuals, sprint numbers are pretty comparable (with fairly accurate linear interpolation) within those shorter time ranges (30s and less).

    I remember when loading data in trainingpeaks that my best 10s was just under 1000W (wow, that is fairly linear). 15s would probably be in high 800s then.

    But then again, my power versus speed shows that I am somewhat a human parachute (i.e. high Cd). I don't get the speed that analyticcyclng.com predicts, unless I set Cd higher than default value.


    Another thing, I remember a friend and I (years ago) would go side-to-side and try to hit our max speeds. Our methodologies were totally different. He would ramp up slowly and it would take him over 30s to hit his max speed. I would reach high speed quickly and hit my max around 20s.

    Just considering our different methodogies, a winner could be clearly identified in a sprinting type event. It would be me just because I got to speed much faster. Our maxes was pretty exact though; just over 30mph.

    You can doubt in one hand and poop in the other, see which one fills up first.

    I think I have touched 40 in my younger days, but that was using an old style magnet speedometer. I always calibrated as best I could though. Now I'm somewhere in the mid to upper 30's, if I'm fresh.

    I am a first year cat 4, 165 lbs, and consider myself more of a climber then anything else. But even at tip top shape and fully fresh I plateau at 36 mph. Cant seem to get past 36, even in a train if i pull out to sprint at 37-39 I will slowly drop to 36. WTH!?!?

    Flat I can ride 25 MPH and hold that with the conditions you've laid out..top speed same condition, 33 MPH my cadence at that speed is upwards of 110 RPM..I'm running a 52 / 11...depending on how I feel I can hold that for quarter mile maybe..
