This run is a secret, don't ask any questions just enter it!.
(especially if you are one of our regular runners, and especially if you aren't one of our regular runners). No more questions, I've said too much - just enter!
This is a running event for absolutely all abilities where you choose - from 5km to 10k, half to marathon to ultra, 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 youï¿½re 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.
Not sure? Well the beauty of this format is that you don't even need to decide in advance - simply come and run a lap and see how you feel on the day and keep on going if it feels right.
Places will be strictly limited so donï¿½t leave it too late to enter.
