Hi guys I usually do my speed session on a treadmil but the gym is shut
So I'm going to try a hill sprint session.
I'll do a 1.5 mile jog to the hill
Then aim for 10x50-100 meter (not sure how long the hill is but its steep)
Walk back down and repeat.
Then a 3 or 4 mile jog back in
Is this a beneficial speed session or would you change it?
