Something new: hill sprints on Heavy Breathing Hill. 25 min warm up via the B+B and then a full run up the hill, then 4 x (10s sprint, 60s recovery), 6 min jog, then another 4 x (10s sprint, 60s recovery).
Think actually efforts were somewhere between 9s and 13s as clearly have very poor time judgement; efforts were a bit all over the shop too, somewhere between 80% and 100% of what they should have been? But it's a start, and session generally felt good: bit of a twinge in left knee, but nothing that lasted.
Run back via B+B and another full run of the hill.
