The Ultra Challenge Experience
UK’s #1 series of treks & trail runs for a wide range of ages, fitness & experience levels.. Choose your Challenge – do it at your pace, and there’re 18 events to choose from. Our support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge! 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, up for more of life’s real challenges – and, maybe, personal horizons redefined!
Good preparation & smart planning are key, and from the moment you sign up you’ll have access to our Challenge App – with training guides, optional training walks, maps, online forums, and the latest news & 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 & welfare tents, catering services, seating areas for recovery, changing rooms, and a friendly welcome!
There’re pink arrows to guide you, distance markers, glow-sticks at night, hazard signs, and a route map in the App. Our ‘Trek Masters’ organise group departures at night so nobody has to walk solo. Our chip timing system enables our Control Room, and your friends / family, to track your progress through the Rest Stops.
Keeping you well fed & hydrated is key. We pride ourselves on the quantity & quality of our catering, and meals, snacks & drinks are included!
- Snacks & drink stops every 12.5 km
- Snacks – from the healthy to treats
- Picnic at 25 km (for 50km participants)
- Energy drinks
- All dietary requirements catered for
- Lighter options for ‘runners’
- Finishers hot meal 50 km (picnic for 25km & 10km)
We’ve experienced Doctors, Paramedics, First Aiders, Podiatrists, and Massage Teams at Rest Stops. There’re ‘Self Help’ areas with blister plasters, talc, Vaseline, and tape if you want to patch your own feet. Our 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 – our 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’re shuttles to local train stations for onward travel, and most finish lines have parking so supporters can meet you. We’ve bus ‘transfers’ to / back to key venues (eg the start) – and check out the ‘Bookable Extras’ for details of all transport options.
Looking for a great event for your team without all the hassle, risk, or costs of organising it? These events are the PERFECT solution – and we had over 400 company teams joining us in 2024.
Your Team will be energised, exercised, bonding & motivated on a fun, accessible, safe, high quality outdoors event. With optional hospitality packages available – make an Ultra Challenge® your company’s special event – maybe supporting your ‘charity of the year’.
