Monster Run route

The Monster Triathlon concludes with an 50k ultra-marathon along the banks of the Thames and the route utilises much of the Thames Path as it winds its way towards the finish venue in Richmond.

This is an ideal opportunity for those in and around London to take part in an ultramarathon, and the event counts for UTMB qualifying points.
