Marshfield is once again preparing to lace up and run the risk of getting gloriously muddy as the much-loved Mudlark returns on Sunday 11th October 2026, starting and finishing again at the Withymead Playing Fields.

For younger runners, the Mudling (ages 4+) promises a 2km lap through the fields and back to the playing fields. The Mudlite offers a gutsy 5km course of off-road fun for adults and juniors (ages 11+). 

The headline event, the Mudlark (ages 16+) sends runners on an 11km course that winds through fields, along lanes, and explores the hilly beauty of St. Catherine's Valley and the surrounding Marshfield countryside. 

Race times will be accurately recorded by DB Max.

There are no entries on the day, so advance sign-up is essential.

This event is organised on behalf of Marshfield Primary School PTA, and your entry helps to raise funds for our fantastic village school. On the day, expect teas and coffees, bacon sandwiches and cakes from the PTA team.
