runner's obliviousness, not runner's high

[lauradi7dw]

I am aware intellectually of the endorphin level rise that happens during exercise, especially that involving the sympathetic nervous system. While I admit I don't know what feeling *high* feels like, I always assumed that I was not getting a runner's high. I think what I actually get is a runner's "don't worry about that right now." I went out at lunch time today and ran for 110 minutes (plus walking 10-15 each before and after). I don't know how far I went, because I have noticed a discrepancy between what I thought and what the trail signs along the Battle Road in the national park say. The running part was at least 9 miles (I started and ended on Mass Ave, ran within the park from Fiske Hill to Nathan Merriam's house and back, with a 3 minute detour to the water fountain at the picnic spot near Hartwell Tavern). That might be more than 10 miles. The route is very squiggly. At any rate, it was longer in minutes than I've run since last fall. At some point I remember noticing a twinge in my left ankle, but carried on. That was probably a mistake. I think I have annoyed the tibialis posterior tendon. I've iced some and it helped, but prevention would have been better than treatment.
