10 Marathons in 10 Days

October 4th 2017 - Dorney Lake, Windsor SL4 6QP

26.2 miles, every day for 10 days straight. Take on one of the most extreme endurance running challenges out there…

This is a multi lap event. The 4.5k out and back route is a smooth tarmac path with grass either side. You start at 1600 daily, so you will be running in the dark for much of your event (which makes for more interesting hallucinations…) You need to finish each marathon within the 10 hour cut off (0200) each day.

This event is limited to just 35 entries, so enter early to avoid missing out.

Only those who risk going too far can possibly find out how far one can go
