The very first triathlon event to take place in the UK was held at the Kirtons Farm Water Sports Centre back in 1983. The venue has now become the Tri2O Swim Centre, based adjacent to the Reading Lake Hotel.

Until 2017, The Reading Triathlon has been run and organised by the experienced events team at My Sporting Times (who also run the Tri2O Swim Centre) since its inception many years ago. Tri2O Triathlon Club took over the organisation of the event in 2017, with a mantra of running a great Tritathlon event, for traithletes, by triathletes.

The Reading Triathlon has three fantastic race options for you. We have a standard distance event, sprint distance and a sprint relay. New for 2020 we launch our inaugural Reading Aquathlon race. 

The Triathlon takes in an open water swim in the lovely waters of the Tri2O lake, followed by a stunning cycle course around the local lanes of Burghfield, Mortimer and Grazeley, before finishing off with a run around the lakeside trail. Look out for our 110% cycle & run sections!

Our Aquathlon comprises of a 1km swim in the lake, followed by a 5.4km run around our lakeside trail.
