Event summary
Here are the distances available for Thorney Island Half Marathon
Route information
With over 1000 runners taking part in 2022, the Thorney Island Trail 1/2 Marathon is the ultimate spring trail run. This amazing route around Thorney Island and the surrounding harbour-side paths makes the most of the stunning views of Chichester Harbour (an Area of Outstanding Natural Beauty) and spectacular wildlife.
The route's remoteness and constant coastal vistas make it one of the south's best-kept secrets. This well-crafted off-road route will guide you around the perimeter of the former airbase at Thorney island, with views over to the Witterings, Prinsted Bay, and the surrounding South Downs.
The flat nature of the course makes it the perfect trail run for attempting your first 1/2 marathon or recording a fast time. With two route distances to choose from (15k, 21k), there is a distance to cater for all abilities.
