Sorry for a bit of thread-hijacking, I don’t have a real answer here but want to share an experience I had last week (and I also try to determine if and when it’s over):
after a winter with ~5 months of doing the running training for a 50k (out of the book), with up to 80k per week, lately my activities focussed more on sportsclimbing, some road cycling and runs inbetween, some trailruns, and/or speedy hikes. So less mileage in running, but still quite active.
Last week I did a hike up a local mountain, ~15k/1200vert/2:56h … quite nice IMO, as I was only 12mins in Z3, the rest below. Felt fit, had the feeling that I was in control. Fast, but not racing, ran downhill the last half (to make it below 3hrs …): nice. No issues after, did some stretching in the evening. Next day climbing, good also, not especially tired or so. It was hot, so I came home in the afternoon, took a nap, and in the evening I decided to do an EASY run of around 8k flat, and hop into the river on my way back.
Did so: after 6k down to the river, went in for ~10 mins, then (without drying: no towel) returned home. Later some stretching, felt a bit stiff, but no pain or so.
At 3am in the morning I wake up with pain in my right knee, could’t find a position to fall asleep again. Over the next hours also my left ankle started hurting, so I basically had issues standing up and walking that day. I can’t remember a specific accident or any twisting or something … very strange. It took 3 days of rest to get this back down, tried easy cycling for a test and to loosen up things. I still feel a rest of that in my ankle, the knee is silent again …
I can’t remember such a “delayed” reaction, does someone have an idea what my body went through here? For sure I somehow did too much, at least that’s my explanation.
Now I am warned in a way and take it easy. High temperatures help to keep the ball low, did some cycling in the morning to test and recreate.
And a swim in the evening, just too cool down and regenerate.
