This event may have been delayed but no matter the completely awesome medal for our SG-100 event can literally take you anywhere in the universe!

The SG-100 is a very special event with a bespoke 100th medal to celebrate the 100th Marathon of a rather lovely young lady, Cathy Holroyd. This medal takes the record for becoming our most expensive medal for a single / standard entry price event and when you see it you'll know why. It's a true work of art which any medal aficionado simply must have in their collection.

This is one of our 7 hour timed events 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 you're both a finisher and a winner in our eyes, or keep going and see how far you can get in the full 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 don't leave it too late to enter.

Minimum distance is 3.28 miles or as far as you can go in 7 hours. The overall course has no elevation gain / loss making this a flat and fast route.

We provide a physical running service and by entering our events you are purchasing an actual run, either by attending our events or by running the event virtually yourself. All participants in our events, both attended and virtual, will receive a free giveaway medal / memento from your run.
