Running intervals 30:00 [5]
This really hurt - a 1k rep up the hill to the park, which left my lungs burning and legs in lactate. Then ran lap intervals in pairs (one running each time). The lap was about 1:10, took 30 seconds straight uphill, then 20 seconds slightly downhill and 20 seconds straight downhill. It really screwed my legs.....oh and then we did 4 x 100m sprints...killer.
