The Beast in the East – 4th July 2021



The Beast in the East is a unique Half distance event situated within convenient travelling distance of London and the South East.

This Middle Distance event consists of a 1.9km swim next to Blue House Farm Nature Reserve on the River Crouch, an 85km cycle taking athletes into the peaceful Essex countryside and finishes with an 18km lapped run based around North Fambridge village with huge support from the local community.
Please note this is a tidal river and will be more challenging than a typical open water or pool swim. Wetsuits are likely to be compulsory and the Swim Cut-Off is strictly 1 hour 10 minutes after the start time.

There is also an aquabike option available.

The triathlon will begin at 8:30am. The start time is dependant on tide times, which we will know closer to the event. All events will take the style of a time trial with athletes starting at short intervals with the fastest athletes starting the swim first. This is based on the estimated finish time given at the checkout when entering. This format may change depending on the Covid restrictions in place at the time.

Many people are understandably nervous regarding entering events again and we want to assure you that we take every measure we can to organise a safe, socially distanced event. To see this in action watch our video Covid-19 Safety at ActiveTrainingWorld Running and Triathlon Events.
