Running intervals 20:00 [5]
another go at some intervals... same set - 4*1km. started well this time but tightened up a fair bit on the third and slowed down. I think I was overstriding a bit too. tried to focus on cadence and foot strike on the 4th... at least didn't get much slower. quite a warm evening again. hips tight afterwards.
