So, I found a field in the park, and ran my 10 dashes today for the first time. I measured it off the map. I sprinted (?) for about 80 m, about 20-30 sec each time (so about 7-9 mph, I am pathetic, I know). That's half of what Mark suggested for distance per sprint. Will it be valid to work my way to 12-16 half-sprints, or do I need to find a larger field so a sprint goes for ~ 1 min? It is very convenient to run in the park at lunch, of course. But do I get any benefit?
