Sunday 25th July, 2021 saw Harrison compete in the Redcar Sprint Triathlon. This was his first event with a sea swim, which proved to be a tad choppy for the 10 am start. He rose to the challenge and managed the swim in time of 12.32. Transitions went well despite all the sand as did the bike leg. The weather warmed up for the run which with no feed stations was a bit grueling but he managed a very respectable overall time of 1.15.51.
