Trifarm Winter 10k Trail Run

About Trifarm Winter 10k Trail Run

Taking place on 27 December 2026, the Trifarm Winter 10k Trail Run marks the final round of a four-event seasonal series. Based at Trifarm in Chelmsfield, Essex, this 10 km trail run follows public footpaths and bridleways with over 95% off-road running. The winter route runs predominantly clockwise and is designed to avoid the river and potential flood risk.

Runners should wear their race number unfolded on the front, as manual timing may be used. There are no water stations on course, though bottled water is available at registration and a tap by the bicycle racks allows bottle top-ups before and after the run. A tail jogger will sweep the route. Food including bacon rolls, tea, coffee and cakes is available for purchase on site, with pre-run swimming and post-run sauna also bookable through the Trifarm website. Race start and finish are located at the far end of the car park, with ample parking available on site.
