Skeg Tri club member and coach Rich Vincent took on the Ultimate Trails 110km - to date his toughest day on two feet.
The trail is one of the most punishing one-day ultra events in the UK.
It started and finished at Ambleside in the Lake District, covering a distance of 110km (66 miles), and a total ascent of more than 16,000 feet.
Rich was one of 333 runners taking on the challenge.
The event started at midnight, so meal times and sleep in the 24 hours before start time had to be planned well in advance.
As this was one of the biggest races Rich had ever entered he was very nervous at the start, and also the weather conditions were not on his side as rain fell heavily and continually.
Carrying all his provisions with him, Rich (pictured) had to keep up a good pace of running and walking to meet the cut-off times throughout the gruelling event.
At one checkpoint Rich was two hours ahead of the cut off time.
The check points along the route provided food, drink and a bit of shelter.
However the weather made the terrain extremely tough and, at times he was ankle deep in mud.
His pace slowed down and he ended his race after completing a gruelling 100km (60 miles) in 22.5 hours.
