Last held in 2016, the event returns in 2026 offering runners the opportunity to take on a truly bucket-list running challenge while raising vital funds for CancerCare.

Every mile across the sands helps ensure that local people affected by cancer have access to the care and support they need.

Whether you're chasing a personal running goal, looking for a unique UK race, or hoping to support a meaningful cause, this is your chance to Beat the Bay. Spaces are expected to fill quickly, so runners are encouraged to secure their place early for this unforgettable running challenge. A runners information pack will be issued to all participants via email from March. Runner safety is our top priority. The Guide to the Sands will assess the Bay in the weeks before the event and on race day. If river conditions are unsafe, we will implement an alternative route on the day, allowing the half marathon to go ahead without crossing the river channel.
