The South Coast Series
Since the first event the River Run, we knew we could develop and make each event tailored to every runner without having multiple distances on the day.
The South Coast series includes 4 main events.

The River Dash - 5k & 10k
The Rings - Marathon & 50K
The Housedean Half - Half Marathon & 10k
Each event is created for different types of runners. Whether you enjoy fast, flat runs or a more technical trail run. The South Coast Series has a run for everyone.
The River Run 2026
Our First Race — and Still a Runner Favourite
Starting in the seaside town of Shoreham-by-Sea, this much-loved race follows the river towards Upper Beeding and Bramber. The route begins by passing the airfield and crossing the historic Old Toll Bridge before joining the Downs Link. Runners loop around Upper Beeding and the iconic Bramber Castle ruins, then return along the opposite side of the river back to the start line. It’s a beautifully scenic and super-flat course with zero elevation gain.
Originally launched as both a Half Marathon and Full Marathon, the event is now dedicated solely to the Half Marathon, with the Full Marathon moving to its own day under a new name — “The Rings.” This allows us to focus entirely on delivering the best possible experience for our half marathon runners each and every year.
The course combines trails, riverside paths, and town pathways, making it one of the most enjoyable and picturesque half marathons in the UK
