The Mortimer 10km has a new look for 2021, with a new multi terrain course and new organisers. As always though, the race will start & finish on Mortimer Fairground, and we have a canicross entry option for those wishing to run the 10km with their dog(s).
PLEASE NOTE - to safely manage the event in accordance with Covid requirements, there will now be no walking event or 1km fun run.
Our new 10km course takes in the beautiful local woodlands, using footpaths and bridleways. The course is undulating and uneven in places, therefore not suitable for pushchairs/buggies or wheelchairs.
