With a start in Chelmsford at the end of the Chelmer and Blackwater navigation, the route follows the waterway on a series of trail, grass and tarmac footpaths all the way through miles of tranquil Essex countryside through to Heybridge Basin, where the half marathon finishes.  A shuttle service will be available between the finish at Heybridge and the start at Chelmsford BEFORE the half marathon. Places on the shuttle can be booked/purchased at time of registration. 

The marathon distance continues through Heybridge Basin, along the Saltmarsh coastal footpath past Goldhanger out to the Wick Nature Reserve, Tollesbury, where it finishes.  We will offer a shuttle service from the finish of the marathon at Tollesbury back to the start in Chelmsford BEFORE the event – tickets for which can be booked/purchased at time of registration. 

The Ultramarathon will continue from the marathon course and head around the coast to Salcott cum Virley where it will finish. If you wish to park in Tollesbury at the Marathon finish, and take the marathon shuttle to the start BEFORE the event, we will get you back to your vehicle from Salcott FOC when you have finished.
