Trifarm 10K Trail Run

Chelmsford, United Kingdom • 9 Sep 2026

Trifarm 10K Autumn Trail Run

The Trifarm 10K Autumn Trail Run is the third installment of a four-part seasonal trail series held in 2026. This 10 km event takes place at Trifarm on Church Road in Boreham. The course is designed to be more than 95% off-road, utilizing a network of public footpaths and bridleways.

The route consists of a clockwise loop that begins with a 3/4 lap of the Trifarm running track. The finish line is located on the west side of the humpback bridge near the public footpath fingerpost. As this run occurs near sunset, participants may finish in low light or darkness; the use of a headtorch and carrying a mobile phone is required for safety.

Participants must wear their race numbers on their front and unfolded to ensure manual timing can be recorded. There are no water stations or marshals positioned along the course, although a tail walker follows the final runners to sweep the route. Water is available during registration and through a refill tap near the finish line by the bicycle rack.

The event is held under a TRA permit. Registration takes place at or near the Trifarm buildings, where on-site parking is available. Participants have the option to purchase discounted swim tickets for the lake at the time of entry. Results are compiled after the event and posted online, with points awarded to the top 15 male and female finishers toward a seasonal championship.
