As part of my current routine, I do a couple of sprint sessions a week. I've read a few articles about the massive benefits, but I'm unsure about how much I should be doing, what distances etc, in order to get an awesome workout but not overdo it.
Currently, I'm keeping it fairly basic. Obviously with a warmup (including stretching), I tend to set out a 100m distance and put 30 minutes on the clock. Sprint 100m, walk back to the start, repeat until 30 minutes is up.
How does this strike you as a workout, in terms of volume, time, distance? Should I be varying the distances, should I be jogging back (i.e. aiming to never be walking), is walking between sprints OK? My past has seen a lot of steady state running, so I'm used to sessions of 30 mins where I finish feeling absolutely drained and pouring... is it OK/normal to not be feeling the same 'drain' after sprints?
Thanks for any guidance!
