ATW Herts & Middlesex Triathlon
30 July 2023
Event Overview
In 2023, we are excited to announce that both the Herts & Middlesex Triathlons will be run from Merchant Taylors School, a stunning venue sitting on the Hertfordshire and Middlesex border with magnificent, picturesque grounds including manicured sports fields, lakes, wildlife and greenery.
Swim in the most popular open-water venue inside the M25, and cycle a surprisingly rural route before enjoying a run around the picturesque grounds of this stunning school.
