Running intervals 10:00 [4]
10*100m with 100m jogging in the breaks, then 4min break and 10*100m more. The first 10*100m we ran on the 400m field, and the second round we ran on the football field in the middle of the track and field stadium. Ran the first 100meters on 17-18sec, and the second round I ran the 100meters on 20sec (the gras is a bit slower).
