Suffolk Coastal Path 50K

The Suffolk Coastal Path 50K is a point to point trail ultramarathon along the Suffolk coast from Lowestoft to Aldeburgh. The current route is 51.5 km and follows a coastal trail that passes through Southwold, Dunwich and Sizewell before finishing on the Aldeburgh seafront.

The route is varied. The first 20 km includes paved paths, quiet country lanes and scenic trails. Later sections run through moorland and forest, skirt Dunwich Heath, pass the edge of RSPB Minsmere and follow coastal footpaths beside Sizewell and Thorpeness. The course is fully marked with orange arrows and ribbons, and marshals assist at road crossings and busier sections. Runners are asked to carry a digital route on a watch or phone as backup.

There are four checkpoints at Benacre (12.3 km), Reydon (21.1 km), Dunwich Church (32.9 km) and Sizewell (45.2 km). Toilets are available at all checkpoints and aid stations provide water, cola, an electrolyte drink, gels and chews, flapjacks, biscuits, crisps, sweets and fresh fruit, with sandwiches available from the second checkpoint onwards.

Entry is open to runners aged 20 and over with no qualifying standard. The event is licensed by the Trail Running Association, is a UTMB World Series Index race, and includes chip timing, a finisher medal, course medical support, bag transfer to the finish and optional coach transfers for a fee. Mandatory kit includes a mobile phone, route map on a device, a refillable hydration system, a soft cup, and a light jacket or emergency blanket.
