This morning was my last run before my first sprint tri on Sun. Very slow, 45 min, probably just over 5k. 64 degrees to start, 65 to finish, a little humid, but I'm enjoying our cold front with some respite from the relentless heat we've had. Did a new trail/path this morning, had to run about 10% on concrete and asphalt, knees staged minor protest at finish, but not too bad. Unfortunately tri route is all concrete, bleh.
