Birchfield Harrier Costellano Tanausu fought off the competition to win the Xtreme Challenge event.
Staged at the Catton Hall Estate near Lichfield, the event sees athletes tackle natural and man-made obstacles.
Muddy conditions underfoot made the course even more challenging this year, but Tanausu completed the course in 36mins 58secs.
He was followed home by Kristian Edwards in 37mins 50secs and Jon Hill in third place with a time of 39mins 3secs.
Meanwhile, in the ladies race Badgers RC runner Nivette Mullen clocked a time of 51mins 3secs to take victory ahead of Jen Seager (52mins 1sec) and Laura Appleby (53mns 11 secs).
More than 300 athletes braved the testing conditions to take part and organisers KP Events say they were pleased with the event.
“The feedback from participants was hugely positive,” said Kevin Wilson from the company.
“Our friends at the Estate along with us at KP Events are already planning changes for 2013.
“We’ll use areas in the Estate as yet unused, look to a one lap circuit with more use of the wonderful natural features as yet unused to vary the terrain and add new twists.”
