The Trail Trot - 5K, 10K, Marathon & 50K

The Trail Trot — A South Downs Trail Running Event

Returning for 2026 with a fresh new name, The Trail Trot builds on the success of last year’s inaugural event, formerly known as The River Run Marathon. With distances ranging from 5K and 10K to a full Marathon and ultra-distance 50K, this South Downs running festival offers something for everyone — from first-time trail runners to experienced endurance athletes.

Set against the stunning backdrop of the South Downs in West Sussex, the event begins on the historic grounds of Lancing College, one of the region’s most iconic landmarks. From here, runners head out across a network of scenic trails, bridleways, and countryside paths that showcase some of the most beautiful landscapes in the South East of England.

The shorter 5K and 10K routes guide runners toward the sweeping hilltop views of Lancing Ring, offering a rewarding introduction to South Downs trail running. Meanwhile, the Marathon and 50K courses venture deeper into the Downs, presenting a more challenging and adventurous journey across rolling hills and ancient landscapes, passing renowned landmarks such as Cissbury Ring, Chanctonbury Ring, and the historic market town of Steyning.

Each route highlights the diverse terrain that makes the South Downs so special — from flowing grassy trails and chalk paths to quiet village footways and panoramic ridgelines. Whether you’re chasing a new personal best or simply soaking in the scenery, every mile offers something memorable.

Whether you’re tackling your first trail race, stepping up to marathon distance, or taking on the ultimate 50K challenge, The Trail Trot promises an unforgettable day of running in the South Downs.
