Not sure how people do max sprints indoors. I feel I need to be able to move the bike, and can’t do that on a static trainer. Plus I’d worry I’d break my bike. Maybe on a high-end trainer or a smart bike?
Most of my high power outputs outdoors have come in situations where I was thinking about speed, not power, and was usually in a lower (easier) gear than I’d select for power. Stuff like getting away from the lights, or through temporary lights, etc. I think that means it’s important to hit high cadence (which for me is about 130), and let the power be whatever it is, and not try and force a high/hard gear up to speed. Though I’m pretty sure that that is individual - some people might be better at generating power at lower cadence, and some might need much higher.
I can hit 120+ for extended periods in VO2 workouts (the entire interval if the power is in range), and hitting 140 in a spin-up happens every time I do it without thinking about it.
Cadence training helps, and I’m far from a highly trained sprinter.
I did just look at my last sprint workout (the first one I’ve done in 6 or more months) and peak power was ~130-140rpm. And, at times I felt like I had it geared a ltitle hard, so it’d easily be higher than that with a little more dialing in.
The hardest thing is to be in the right gear right? Too easy makes it hard to hold the resistance after speeding up. Too hard and producing the power is hard.
And I‘m probably not strong enough to compensate wrong gear choice.
OP asked about doing 1000W. You can use the downhill to go to high cadence on the biggest gear and continue that for a few seconds into the uphill. It’s possible to do it for 5-10 seconds. 200 rpm is doable for me. I assumed everyone can, but regardless just go to the highest cadence you can sustain for 20 seconds.
