The Saltmarsh 75

The Saltmarsh 75 is a coastal ultramarathon of approximately 75 miles along the Essex saltmarsh coastline between South Woodham Ferrers and Salcott. The event is staged from Marsh Farm Country Park in South Woodham Ferrers and is open to runners and walkers.

This edition offers multiple entry formats including a traditional two day option, a continuous 75 mile option and a three person relay available for single day, two day and continuous entries. Shuttle services operate over the weekend to move participants between finish and start locations for the chosen format.

All participants are tracked with individual GPS devices and must check in at designated checkpoints. GPS tracking is available to participants and their family or friends via the event app. The route is marked at key points but not extensively; GPX files and route details are provided for download. Aid stations and checkpoints are provided at regular intervals, approximately every 10 to 15 km, with hot food and drinks at locations such as Steeple and Tollesbury. A first aid team and 4x4 access teams are in place and agreements exist with local landowners to assist access to remote sections.

The event is cupless; participants are expected to provide their own drink container. Participant information contains details on cut off times, mandatory kit lists, bag drop and aid station provisions. Entry price is listed as GBP 100 and finishers receive a bespoke medal, goody bag and finisher t-shirt. Visit the organization's website for the most recent information.
