We are excited to announce that the Hertfordshire & Middlesex Duathlon will be taking place at 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.

The Run is a flat 2.5km lap of the beautiful lake, returning to the playing fields at the end of each lap for a quick trip to the running track before heading back out to the lake.  

Cycle a surprisingly rural route before enjoying a final run around the picturesque grounds of this stunning school.

This is a mass-start non-draft legal event with starts from 8:30am with three distances to choose from:
- SuperSprint - 2.5km run - 12km Bike - 2.5km Run
