The racers were set off by Mike Rouse, Mayor of Ely, on Sunday, August 19 at 7am with a second race launched at 7.30am.

On social media, Mr Rouse said: “What a way to send a Sunday morning, glad I only had to press the klaxon.”

Competitors spotted a problem during the race. One of the guide buoys had drifted, making them swim further than planned. However no one seemed to mind.

One competitor said: “Thank you for a fantastic event! OK, so we swam a bit further than planned but these things happen.”

Another added: Great race anyway - really good atmosphere and the river is nice to swim in - which is just as well given we were in there ages. Would recommend ya.”

Nathan Ford, 34, of the Nathan Ford Triathlon Coaching club claimed first place in the Monster Middle race with a total time of 4 hours 25 minutes and 27 seconds.
