Some 518 entrants from as far away as Cyprus have signed up for the second Tough Mann Adventure Race.
Event organiser Richard Cryer promised the new 10km Dragon’s Head course at Ballamoar Farm in Ballaugh will be ‘bigger, badder and muddier than ever’.
Saturday’s event will see competitors – taking part individually and in teams of three – running, walking and crawling through the countryside clambering their way over 25 ‘exciting’ obstacles.
Entrants, a huge rise on the 300 that took part in last year’s event, are heading to the island from Cyprus and the Channel Islands to take part.
Mr Cryer attributed the success to word of mouth after last year, as well as their website.
Kez Wardell is the brainchild of the course layout.
Obstacles will include abandoned cars to jump over, a monster hill climb to scale, hay bales to clamber over, cargo nets to go under, and muddy bogs which were topped up with the rainfall at the weekend.
Competitors, about 40 per cent of whom are female, will also face a rope scramble, telegraph poles, a gator crawl and face the possibility of being jet washed.
They can also expect to become tangled in the woods, encounter a gunk tank with ice blocks, monkey bars and a gorse maze as you traverse the course.
Everyone who completes the course will receive a victory Bushy’s beer and victory T-shirt.
Mr Cryer said: ‘We have gone on a bigger scale. It’s a bit more difficult but more fun as well.
‘We have kept it so everyone can do the event without any training.
He said that they were working hard to make the final preparations.
‘Because we are on a live farm there are lots of things that can’t be done until the last four or five days,’ he said.
Obstacles are now being tested ahead of the race getting under way at 1pm on Saturday.
As well as a new course, there will also be improved spectator facilities as they hope to create a fun day out for all the family.
They expect to build on the 1,000 strong crowd that turned out last year.
‘We have worked hard to improve the specatators’ area,’ Mr Cryer said.
The start and finish have been moved and spectators will be able to watch competitors tackle a number of obstacles in an arena.
Bushy’s beer tent will also be on site, as well as children’s entertainment, food vans and live music.
