Up for the ultimate endurance challenge? If you love the outdoors and are looking for the ultimate challenge, Oxfam’s Trailtrekker and Trailwalker are definitely for you. These were originally an elite Gurkha training exercise, but the events are now some of the biggest team endurance challenges in the UK. The course is a 100km off-road trek across the South Downs or Yorkshire Dales, and teams of four are given a maximum of 30 hours to complete the challenge. The teams have their own goals, from the elite tier hoping to complete the course in less than 12 hours to the first time outdoor lovers simply aiming to complete the course for a challenge. The challenge is remarkable, the atmosphere and routes are breath-taking, and completing the challenge leaves you with an unrivalled sense of achievement. The event is definitely only suited for those looking for a challenge, covering two and a half marathons non-stop and pushing your fitness to the limits, whilst working to keep yourself and your team motivated throughout. The achievement does not come without hard work, but the accomplishment is huge, and you are raising money to change other people’s lives whilst you do it. Trailtrekker: 31st May – 1st June 2014 Trailtrekker has a dramatic and rugged circular route following the Pennine Way through the prehistoric Malham Cove and over Fountain’s Fell whilst travelling across moorland and through deep valleys. There are smaller challenges available too, with teams being able to choose from the 100km Gold Challenge or opt for the 65km Silver or 40km Bronze distances. Trailtrekker: 31st May – 1st June 2014 Trailwalker: 26th July – 27th July 2014 Trailwalker’s route in South Downs follows flint tracks across rolling countryside with steep scarp slopes, beginning Petersfield and following the South Downs Way to Brighton, passing several beauty spots including Devil’s Dyke and Jack and Jill Hill. Trailwalker: 26th July – 27th July 2014 The event is supported by the Gurkhas, with the logistics explained by them and 250 Gurkhas also completing the courses for the honour of joining their regiment’s Trailwalker team. To date the Gurkha teams have never been beaten at any of the challenges. As well as supporting Oxfam, the sponsorship you raise will go towards the Gurkha Welfare Trust, supporting retied Gurkhas and their families in Nepal. If you feel you’re up to the challenge, take on the Oxfam Trailtrekker or Trailwalker.
