Trail run

Butcombe Trail Ultra

Butcombe Trail Ultra takes place on Sat, Apr 17, 2027 in Churchill, United Kingdom. The main route is 81 km.

The Butcombe Trail Ultra consists of 50-mile and 50-kilometre self-navigation trail ultramarathons set in the scenic Mendip Hills.

What this race demands

The Butcombe Trail Ultra requires sustaining forward motion across an 81 km self-navigated trail route with 1960 meters of elevation gain in April.

Endurance capacity

Covering 81 km demands prolonged aerobic output and resilience against muscular fatigue over many hours.

Climbing volume

The 1960 meters of elevation gain require consistent uphill pacing and muscular strength to handle sustained ascents.

Self-sufficiency

Self-navigation over an ultramarathon distance requires sustained focus, pacing discipline, and independent nutrition management.

Given the duration of an 81 km ultramarathon, athletes should aim for 60 to 90 grams of carbohydrates per hour to maintain energy levels.
