TOUGH Mudder has revealed its obstacle line-up for the 2018 race season.

It includes the challenges that will be faced by participants across the North West.

Tough Mudder, dubbed the world’s hardest endurance mud run, announced in 2017 that it would be launching a new 5k course in Heaton Park, Prestwich.

The 'most challenging obstacle yet' has now been introduced by organisers for 2018.

Kong Infinity, the brainchild of Glaswegians Ross Munro and Jonny McDonald, will see participants climb a 15-foot structure to reach a barrel which has handles fixed to it.

The barrel is set on tracks which are suspended more than 20 feet from the ground.

Using momentum to carry them, residents will rotate the barrel along the tracks to reach the other side.

Tough Mudder has also introduced the largest structure to ever feature in the course.

Happy Ending - the new finisher obstacle - requires participants to climb their way up a 20-foot tall structure, complete with 40 and 45-degree angles.

Once reaching the summit, participants then dive down a 25-foot slide into a water pit.

CEO and co-founder Will Dean said: "We look forward to welcoming thousands of new and returning participants to Mudder Nation in 2018 to face these challenges together.

"We remain dedicated to engineering ways to challenge our participants, both physically and mentally, all while giving millions of people a 'Happy Ending' and creating an exciting environment that showcases how we are stronger when we are united."

He added: "Tough Mudder is making a concerted effort to invest in both the Tough Mudder 5K and Tough Mudder Half to provide accessible, yet rewarding experiences, to so many runners and outdoor enthusiasts who are not being challenged or excited by ordinary 5K runs or marathons."
