Power is something I never had. Lots of training made mine 'average' or just below, so long as I was well-carbed. Low-carbed, I was too weak to achieve anything. Power is not really an issue now; there is none. I'm working on weight.
David gained power when he overate a couple of years ago. He lost weight and strength last year. Seems to be getting stronger now.
Everybody has a power value and a weight value. Your power value may be small, even zero, but you still have one.
I'd like access to a PowerTap so I could quantify my own power over a given period and then create my own Watts/Kg value. That way I could see actual improvements. I'd like to be able to quantify what a Pro Cyclist is actually like as well. Watts/Kg gives you that.
Like Boabacca I'm looking to improve my power to weight. I'm 50 so my power isn't going to improve much so that leaves my weight.
Hauling excess weight up hills (or even up gentle slopes) wastes what little power value I have, takes me further into "the red" than I need to be, requires more calories...etc etc. It's a constant drain in a hilly world.
I'll never have Wiggo's power level but I wouldn't mind trying his body weight, even with my power. He's 3 stone lighter than me (he's bloody taller as well). 42 pounds !!! He puts out >400 Watts as well. I'm not surprised he likes cycling.
Cycling is just better when you're lighter.
