Double Hill PB

Double Hill again last night and a new PB, despite feeling distinctly off-color for the first half and actually walking twice due to various complaints. However I somehow managed to reach the bottom of the final hill a few seconds ahead of PB pace and finished in 1:04:02, shaving 9 secs off my previous best. I must admit though my max HR of 179bpm up the hill was too high for comfort!
