The TRI Challenge Team Triathlon

Organiser's Description

The ultimate team relay triathlon. All team members complete all disciplines – the first person swims, tags the next, who then completes the swim, etc etc. Then they cycle, then they run! The event is electric, one not to be missed. Awesome fun, great atmosphere and perfect for everyone, from those starting out to the hardy triathlete.

A 400m swim in Dorney Lake is followed by a flat 15k bike and 5k run.
