cycling (spin bike intervals) 27:19  9.2 mi (2:58 / mi) ahr:139 max:169
really like the spin bike, went for the top effort level today.
running (treadmill intervals) 20:17  3.18 km (6:23 / km) ahr:162 max:175
Thought i'd continue the interval theme on the treadmill. On my last 400m sprint and had sudden pain in R calf. Now limping. Was feeling quite good as well although HR suggests I was maybe pushing too hard. Back to being a couch potato for a while.
