Well I accidentally did a 35 mile run today in the howling wind too! Missed a turn and added five which turned out to be a bit of a bugger because the old right knee gave out on me about four miles out from home so I had to limp back yet again. So frustrating especially when the rest of me felt good enough to go further. Ah well, maybe I'll be limited as to mileage but I can stilll enjoy the rides the knee will let me get in!
Seeing a Physio before long so maybe they can shed light on my problem.
Another plus tho is that the saddle I thought I was going to have to replace is fine, just dropped it a little and put a very slight nose down angle (it has a pronounced hump just where you don't need it...) and had no pain in the bum at all!
