M12k A Brief History:


The Marnhull 12k was brought back to life in April 2016 by a couple of Dorset Doddlers and St Gregory’s School PTFA. The original race was held some years ago and we still follow most of the original route.

We are very proud of our race, all proceeds help fund St Gregory’s Primary School.   You’ll see lots of people from the local community all helping deliver an enjoyable, safe experience for runners and supporters alike.

All proceeds from the day will go directly to the school, in the past the race has helped fund the swimming pool and other valuable resources.  Your support makes a real difference to the children.

On this page you’ll find lots of information and updates will appear as and when we’ve got any news.  Be sure to check the course in our video below.

We don’t want anyone leaving us without a full belly, you’ll have hog baps, bacon rolls, hotdogs, burgers or tea and cake to enjoy at the finish line. 

Fancy yourself as quick? why not try and better our male and female course records noted below along with archive results.

The Route


Commencing on New Street in Marnhull before taking in Fifehead Magdalen and then returning to St Gregory’s School the M12k is best described as undulating.

A challenge for all abilities, there’s ups , downs and a bit of flat, the scenery shows North Dorset at it’s best with winding country lanes and some great views, particularly as you crest the climb atop Fifehead Magdalen.

Take a look at out course video for a better insight, this was shot during the colder months so please expect the course to be greener come April.
