Visit the official website

ActiveTrainingWorld are excited to announce the fourth Run Fest At Lee Valley.  This event replaces the cancelled event earlier this year and is sure to be a sell out.

The event features a 5K and a 10K race (no Half Marathon this time) which starts and finishes at the Lee Valley Regional Park before heading out to the beautiful park that surrounds the White Water Centre. The course is traffic free, flat and fast so not only can you smash your personal best but you can also enjoy fantastic scenery whilst you are doing it!

In order to maintain social distancing, the 10K event will be held in 2 waves for sub and plus 50 minute athletes. For this reason, it is important that you enter your estimated run time when completing your registration.

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

This is race is  extremely popular. Enter now to avoid missing out!
