I've done a lot of 11 mile bike rides and 3 mile runs. Right now I want to increase my 60 second power to weight ratio. I'm 5'7", 147 pounds, and can output 350 watts for 60 seconds. I can output 500W for 20 seconds. I can output 200 or so for at least 30 minutes.
My goal is to lose at least 10 pounds (yes, I'll be gaunt, but for a good reason) and increase my 60 second power output to 500 watts in the next 4 months. Is that a lofty goal?
