Weird

Last treadmill run of the week.   Its been a busy somewhat stressful evening at work.  HR was much higher then usual in the 140's after 2K pushing up to 151...YIKES.   Last couple of days its been normal ... high 130's but today it was 10-12 bpm higher.   Its a great mystery however I suspect stress or perhaps I subconscious know what I am about to do this weekend or perhaps it  has something to do with what I did last weekend however the last couple of runs have been normal ... so fickled!
