The Cross Bay Half Marathon 2026: A Truly Unique UK Half Marathon

Runners looking for a truly unforgettable race experience can celebrate the return of the Cross Bay Half-Marathon on Saturday 4 July 2026.

This extraordinary 13.1-mile race takes participants across the tidal sands of Morecambe Bay, making it one of the most unique half marathons in the UK — and widely believed to be the only half-marathon in the world that crosses a tidal bay.

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. If you’re searching for a different kind of running event, this could be the ultimate test.

A Half-Marathon Route Across Morecambe Bay

The Cross Bay Half-Marathon begins on the beautiful coastline of Arnside, with the race starting at Arnside Promenade. From here, runners head out across the vast tidal flats of Morecambe Bay, navigating a route that combines firm sands, shallow channels and wide open views across one of Britain’s most spectacular coastal landscapes. The course winds its way across the bay before finishing at Cark Airfield, where runners will be welcomed into a lively Runner’s Village to celebrate their achievement.

Guiding participants safely across the bay will be Michael Wilson, the official King’s Guide to the Sands. This historic role has existed for centuries, helping travellers navigate the shifting sands and tidal channels of Morecambe Bay. With his expert guidance, runners will follow one of the region’s most historic routes across the bay.

Imagine running across stunning Morecambe Bay (with the tide out!)

Support Local People Affected by Cancer

The Cross Bay Half-Marathon is more than just an incredible running challenge. It’s also an opportunity to support people in the local community facing cancer and bereavement. Funds raised from the event support the vital work of CancerCare, which provides counselling, support services and practical help for individuals and families across the North West.

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

One of the Most Unique Half Marathons in the UK

There are many half marathons across the UK — but none quite like this. Running across the tidal sands of Morecambe Bay is an experience few races can match. With incredible scenery, a historic route, and a powerful community cause at its heart, the Cross Bay Half-Marathon offers something truly special.

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.
