Fixed timed runs
Explore fixed time runs across the UK and challenge yourself to cover as much distance as possible within a set time. From short timed events to multi-day endurance tests, use the filters to find fixed time runs by date and location. Read more
Fixed time runs flip traditional racing on its head. Instead of chasing a set distance, you run for a fixed duration — anything from one hour to 24 hours or more — with the goal of covering as much ground as you can before the clock runs out.
Many fixed-time events take place on looped courses, making pacing, fuelling and mental resilience just as important as physical fitness. Some formats allow short breaks, while others push competitors to keep moving for as long as possible.
These events appeal to runners who enjoy testing limits, managing fatigue and staying focused over long periods. Whether you’re new to endurance challenges or an experienced ultra runner looking for something different, fixed time runs offer a unique way to measure progress.
Use the filters to narrow down events by date and location — then decide how long you’re prepared to keep going.
