The Ultra Challenge experience

Endurance events for a wide range of fitness and ages. Choose your Challenge – do it at your pace, and there’re 18 events in the series. Support from our fundraising team and from Ultra Challenges enables you to go further, whilst enjoying the great outdoors & camaraderie. There are marquee rest stops, lots of food & drink, medical & massage teams, with a fully signed route to guide you. A big finish-line celebration awaits with an amazing sense of achievement, and once the aches subside you’ll feel energised, and up for more of life’s real challenges!

Good preparation and smart planning are key and from the moment you sign up you’ll have access to the Ultra Challenge App – with training guides, optional training walks, maps, online forums, and the latest news and updates.

Rest stops every ~12.5 km with ‘major’ ones every ~25 km, and are much more than the shaky gazebo with water that you see on some events. We’ve marquee cover, large medical and welfare tents, catering services, seating areas for recovery, changing rooms, and a friendly welcome!

There are pink arrows to guide you, distance markers, glow-sticks at night, hazard signs, and a route map in the App. Ultra Challenge's ‘Trek Masters’ organise group departures at night so nobody has to walk solo. The chip timing system enables the Control Room, and your friends / family, to track your progress through the rest Sstops.

 

Keeping you well fed and hydrated is key. Ultra Challenges pride themselves on the quantity and quality of their catering, and whichever distance you are on – meals, snacks and drinks are included – so no need to carry much!

• Snacks – from the healthy to treats

• Main meals / hot food every 25 km

• Energy drinks

• All dietary requirements catered for

• Lighter options for runners

Ultra Challenges have experienced doctors, paramedics, first aiders, podiatrists, and massage teams at rest stops. There are ‘Self help’ areas with blister plasters, talc, Vaseline, and tape if you want to patch your own feet. Their mobile emergency medical teams are only a phone call away, via our 24 hour Control Room

We don’t want you to forget that finish-line moment – Ultra Challenge's Cheer Squad will ensure you won’t! You’ll get a medal, finisher’s T-shirt, and a glass of fizz, before heading to a BBQ and a well earned rest. Download your official Challenge certificate when you’re ready.

There are shuttles to local train stations for onward travel, and most finish lines have parking so supporters can meet you. There are bus transfers to / back to key venues (e.g the start) – and check out the bookable extras for details of all transport options.
