I've always been like that though, that leg burn is way too painful to endure. Like weightlifting it's a burnout set and when the lactic acid builds up I'm pretty much done. My rides are 30+ mile loops, so I can't afford to be spent early in the ride and I try to distribute the workload throughout the marathon rather than in a sprint.

Oh, and as for cadence, I really haven't quantified it by measuring, just going by what feels better and that's why I'm glad I have the road bike with the gears so that I can physically do it by trial and error rather than having to take the bike apart and putting it back together with a SS/FG to experiment. When I bought the Vilano, it was a matter of comparing the GI computation. I think I could have probably gone with a 48T crank gear instead of 46T. While the GI matches the road bike, the Track bike is lighter, so pedaling it, I think I can get a few more GI and still be fine under certain land/road & wind conditions ? I guess that's where I'd have to fine tune and really start swapping gears, whether it be at the crank or rear wheel/hub ?
