Fancy dress is very much the order of the day, so it's time to get your 50's gear out and run like lightning.

This is a 6 hour timed event where you choose - from 5km to ultra marathon, you can complete as many, or as few, laps as you like of a 5.3km, 3.28 mile, out and back, course along the beautiful river Thames. We welcome all abilities of runner - complete one lap and you're both a finisher and a winner in our eyes, or keep going and see how far you can get in the full 6 hour time limit and everyone gets the fabulous bespoke finishers' medal.
