Herts Tri

Welcome to the 5th year of the Hertfordshire Triathlon!

There will be live commentary, music and race photography as you celebrate your achievements with your friends and family.

The Hertfordshire Triathlon has seen some famous faces over the years. Mark Buckingham, ex-pro GB triathlete has raced, along with Lucy Charles and Reece Barclay, pro Ironman triathlete who won both the spring and summer 2016 Herts Club Championship races. 

Lucy and Reece have since been back to announce the winners of the race, so if you fancy seeing some celebrity faces, come down to Stanborough Lakes this spring and summer.
