About

A flat, fast half marathon that follows riverside towpaths and traffic-free suburban roads beside the River Thames. England Athletics certified and clearly measured, the course passes local landmarks and provides pacers and sweep marshals. The event includes first aid cover, race photography and race-number collection options, with bespoke finisher mugs, medals, tech tees and goody bags for finishers.
