JLL Property Triathlon - August 20th 2021

Dorney Lake, Eton

Water Temperature 2020: COVID19

Water Temperature 2019: 18℃

Water Temperature 2018: 16℃

  • The JLL Property Triathlon is organised by Human Race and takes place at Dorney Lake – the location of the Olympic rowing events amongst others at the London Olympics 2012.

    The event which now includes a sprint distance triathlon, duathlon, 2.2K swim and a growing fancy dress wave has something to offer everyone. It’s a fun and inclusive way for people of different ages and abilities to come together, and whether competing or spectating, it’s an opportunity to meet colleagues and friends or make new business connections.

    We estimate a cool 14 degrees as the water is still quite cold after the cold March and April. If we get a warm spell, this could warm quickly as the water is not deep. In 2010 the water reached temperatures of above 21℃ during the summer months!

    We encourage JLL Property Triathlon participants to consider for their open water swimming needs. We feature the latest wetsuits from the most trusted Triathlon Brands including Zone3.
