Distance & Time

This is a 7 hour Time Challenge event which allows you full control over the distance you want to run. The minimum distance is 3km, which is part of a lap. A full lap is 4.37 miles or 7km (this is subject to change to a 3.28 mile loop depending on course conditions) and you can run as many, or as few, of these laps as you like subject to UK athletics age restrictions (please see the restrictions below). We will have a 3k turn point and 5k turn point within the lap which is available to allow our younger runners to comply with the UK Athletics distance rules. It is 3 laps for a half marathon, 6 for a marathon and 7 or over for an ultra, we also have a 50km distance available.

Course

The course along a beautiful stretch of the River Thames. It is fully signed so no navigational experience is required. The course is mainly well made paths and tarmac with a very short grass section. Road shoes are suitable all year round.

Medals & Pins

As long as you complete 3km, you will be an official finisher and you will receive one of our fantastic Halloween themed medals! We also have distance pins available for anyone who runs a half-marathon distance or more. Pins available to collect are our Half-Marathon, Mega-Half, Marathon, 50km and Ultra pins. You will receive one pin on the ribbon of your medal to reflect your achievement.

Goody Bag

Absolutely! You earned the calories after all, so all our finishers get a goody bag. As well as our standard goody bag, with a selection of various goodies to choose from, we also have a fabulous vegan goody bag for our vegan runners.
