Entries are now open to take on an annual 50-mile challenge.

The Saltmarsh Ultra and Saltmarsh Half marathon entries are now open, which will see runners test their limits across the length of Maldon district's coast line.

Saltmarsh Ultra, which is in total 50.6-miles will start from South Woodham Ferrers, around the Dengie peninsular before finish at Promenade Park.

The Saltmarsh Ultra is open to runners, walkers, duos and relay teams, extending the previous single day distance by a further 13 miles.

The Saltmarsh Half Marathon will cover 13.5 miles of the Saltmarsh Coast Trail along the River Crouch from South Woodham Ferrers to Burnham-on-Crouch and the beautiful Riverside Park. The route is almost entirely off road and open to runners and walkers. Free return transport is available from the finish back to the start.

Spaces will be limited for both of these fully-supported, landmark events.
