Oh…my watt/kg ratio isn’t very good. I’m 6’0"" and have a lean body mass (at 0% fat) of 181 lbs. Essentially, I’m built like a track racer but also have a few pounds to lose. Even in my 50s I can pull 1500 watts on a watt bike over a 6 second interval. However, you put me on a hill and I’m not going to keep up with seasoned racers. I do have a pretty good power to drag coefficient, so I do well on flat courses. I averaged about 23 mph last season on the bike and am hoping to get up an 25 mph this season on the bike. The running? 8 minute mile on my last sprint. I really want to get that down around 6:30 or 7:00, but I’m gonna have to lose 25 lbs to do it.
