The course is defined by its lack of hills. Over the 100 mile (161km) distance, the route accumulates a mere 560m (1,900ft) of elevation gain, making it one of the flattest 100 mile ultras in the UK. The challenge here is not in conquering mountains, but in managing the relentless, repetitive nature of the flat terrain, which tests your mental fortitude and pacing strategy to the absolute limit.
