Power/Weight

[dumbod]

Can anybody point me to a formula/table/site/whatever that will allow me to determine the power/weight ratio I need to generate in order to climb a given grade at a given speed?

Thanks.

The most basic way for me to look at it is this:

Power = Force X Velocity


The most difficult part is figuring what the force working against the rider is, but once you have a feel for that it gives you a lot of insight on the fly.

If I lose 22 pounds (my immediate goal), I'll increase my time on a local climb by 139 seconds.... that is pretty fantastic! (assuming I maintain the same power).

It'll bring me up 15 spots on the Strava leaderboard, to 80th! :crap:

If you lose most of that 22 lbs through cycling (mostly) you will go up way more than 15 spots!

I speak from my experience anyway. After graduating this past fall and after two years on hiatus of mostly commuting, I got back into a regular cycling mode, lost almost 20 lbs, and lost almost 10 min on my fav climb! Stupid Ted king is faster by another ten minutes but he's a pro so I'll just keep my damn slow pace for now.

Chances are that if you lose 22 pounds you'll actually gain power and ride up even faster than that.;)

That's the way it has always worked for me. May lose a little muscular strength (mostly while weight is coming off and not so much after) but my capacity to generate power goes up rather than down.

My experience, from the 200+ pound perspective, is that a 5% reduction in weight improves my climbing speed by 10%. That is, when I lose weight by working out, the power gain from better fitness roughly matches the weight reduction. i suspect this is les true for people who start out in better shape.
