Notes
Really odd workout. 1st interval felt really comfortable. Then, 30 sec. into 2nd interval, could feel my heart fluttering and could tell my circulation was not working. Fell off pace for 4 laps, but then caught up again to Pat at the end. Same thing happened in the 3rd interval, but not as severe. 4th interval felt the smoothest. Left shoulder really starting to stiffen up.
