I do 6 x 50 meters at half speed and then 6 x 50 all out with a 400 meter warm up.
The first attempt left my lower body in shambles. The 2nd attempt was better but I was still sore for 3 days and my latest attempt felt really good.
I'm surprised that there's so many muscles that I wasn't hitting with distance running, swimming or weights in the past.
I'll start mixing in hill sprints and working up to 100 meter workouts eventually.
