So I'm a fat fucker, 6ft 300lbs. Today I decided to start young more running at practice and ended the day with 20m sprints. I set my Par time for 4 seconds and could only barely make it. First time ever trying flat out. The first 6 runs were 3 at 7 seconds and 3 at 5 seconds. Easily making that I reduced to 4 for the next 10. I probably look like a penguin trying to run, but whatever. Heart rate was pounding (no idea on actual) and shots at 25 still stayed in the 8in circle (10 shots in 6 seconds).
So, the shooting I'm not so worried about, the sprints I'm curious about, beyond dropping pounds what sort of realistic time should I be looking at for 20m?
