Hyde Park laps/8s. Tried to run below 125bpm but there was something wrong with either the HRM or my heart - on the first lap HR jumped to over 150, and couldn't get it below 140 for another lap. It then varied between 135-145 for another lap. Finally settled down and read 125-128 for the last couple of laps. I suspect it may have something to do with the major power line running through the park. Certainly didn't seem like my heart was ever beating that fast.
