Running intervals (Track 6*1km) 20:13 [5] 6.0 km (3:22 / km)
shoes: Saucony Endorphin Racer
Felt pretty flat coming into this session and my stride dynamics seem to have gone a little weird, possibly something happening with the barefoot shoes. Will try and run 50/50 with flats for the moment. 3:21, 3:24, 3:22, 3:22, 3:20, 3:24 (target 3:23) w 45 sec rests. Last one was a struggle, had a return of the knee lockup I got a bit last year which was annoying.
Running 24:20 [1] 5.4 km (4:30 / km) +73m 4:13 / km

Cut back on the warm down - got a blister again where I got a blister last week! A bit random, I changed socks thinking that was the cause but must be the shoe itself slowly disintegrating (wore flats for the intervals)
