ATW Hertfordshire & Middlesex Duathlon

The Merchant Taylors' Duathlon offers a well-paced, multi-discipline race on the edge of Hertfordshire and Middlesex. Athletes begin with a flat 2.5K run that loops around a private lake, followed by a bike segment on quiet rural roads. The final run takes place within the landscaped grounds of the stunning Merchant Taylors’ School, covering paths, fields, and open green space.
With low traffic, clear signage, and a calm race-day environment, it’s well-suited for both experienced competitors and those testing race strategy.
