The Loop London
Challenge description
​
The Loop London is a 170 mile non-stop ultra following a modified version of ‘The London Loop’ trail starting and finishing at Cockfosters station with a time limit of 45 hours.

We will be running clockwise following the London Loop markers and GPX. At around 35 miles you will follow the modified route towards Londons Docklands/Canary Wharf area then through the Greenwich foot tunnel under the Thames.
