running intervals (treadmill) 30:00 [4]
max:170 shoes: Pegasus 2
8 x 400m with 400m recovery. Though it takes a bit for the treadmill to slow down again! And I try to start it speeding up before the interval starts.
Went from 10.3 mph to 10.8 mph, which got me down to 5:33 pace I think. Started at 5:48 pace.
170 is 'the new 180' in terms of my heart rate ... goes with the grey hair I guess.
