My legs are REALLY sore! Did 3 miles in the neighborhood in 34 min. 22 sec. I tried to increase my intervals to 6 1/2 minute run / 50 minute walk.....but I somehow screwed up my timer on my GPS....after the 3rd walk break I was thinking boy these walk break are going by way too fast so I happened to pay attention the next time around and I somehow had it timed for 30 seconds instead of 50. So my legs started to revolt...I swear it's all psychological....because until I knew that I messed my timer up I was doing just fine. Go figure! Oh well...Really looking forward to giving my body a break tomorrow!
