Running 16:01 [3] 3.87 km (4:08 / km) +29m 3:59 / km
ahr:132 max:171
4x4mins to give the calf a chance to recover…
…but then as I was doing intervals anyway, I figured I might as well throw in a couple of fast ones: 3.58 and 3.51 per km
Definitely the first time in 3+ years that I’ve done a km in under 4 minutes. Felt tough but kinda good. Maybe a sub-3h marathon is still possible after all?
