Nick Maddison is just one event away from completing his energy-sapping 12 months of extreme endurance events... all in the name of charity.
The 31-year-old will take on the Wild Warrior challenge in Derby this weekend, braving 10k of mud running and gruelling obstacles.
But as he crosses the finish line, it will mark a calendar year since he began his extreme mission - which has included some of the country’s toughest obstacle courses, ultra races, five marathons and his latest challenge.
On Saturday, Maddison set off to run the cycle course from Boston to Lincoln.
He completed the 34-mile task before running 17 miles back on Sunday, reaching Kirkstead Bridge.
His dad Paul Maddison cycled alongside him in the treacherous conditions on Saturday.
But what was feared to be a broken bike chain and the extreme weather saw the pair decide to call time on their final challenge, which would have seen Maddison junior run from London to Brighton, with his dad behind on two wheels.
“We just realised that it’s something where you need a proper team behind you,” Maddison said. “This weekend will be the last one. It will be my 25th event.”
Maddison began his year of challenges to raise chash for the Alzheimer’s Society in memory of his grandad Norman Sculthorpe. He has just reached the £2,000 mark, but you can still sponsor him at http://www.justgiving.com/Nick-maddison22
