The knees got three weeks to recover after a hard 20k trail run. Tonight was the first time testing them. Back on the trails we went and just to keep it loose I decided to keep the heartrate under the aerobic limit. Tried to keep it under 160 mostly but let it go a bit over that on a few steep spots. This worked OK but I had to keep telling myself not to look at pace. Allowing myself an extra 10-15bpm shortens each mile by about 90 seconds. May try this for a while, there's nothing to prove trying to set PRs every time out on my favorite loops.
PS. Did you know that high pressure bicycle tires lose PSI fast even without leaks? Fast = 15 PSI overnight. I did not know that. But hey, going for that 3 hour ride a few weeks ago with 50 PSI in the tires just made the workout better, right?
