Your Way!
Endurance style events at your pace, for a wide range of fitness levels, ages & experience. For teams & individuals; for a charity of your choice; OR just do it for yourself and achieve something special. No obstacles or mud pools, just wonderful countryside; full support all the way; lots of food & drink; camaraderie, and your spirit & determination.
With 18 events – 25 km, 50 km distance choices; 100 km continuous challenges or over 2 days with the Daylight option if you want to step it up; a few trail marathons; a dozen 10 km taster events, and a new Ultra March® category – there’s an Ultra Challenge® for EVERYONE!
YOUR CHALLENGE – YOUR WAY
Most walk, many jog, some may try both and see how it goes. At the front runners may be stepping up from a marathon, testing themselves against the clock, or just trying out trail running.
Ultra Challenges are for ALL. On the 50 & 100 km ‘Ultra’ distances, 51% are female (2024), with all ages taking part as well as a wide range of experience & fitness levels.
If you want to step up to a full 100 km Ultra for the 1st time – there’s the ‘2 DAY DAYLIGHT’ option, with camping at half way.
There’s also the ULTRA MARCH® category for like-minded walkers with a clear goal of completing 100 km in less than 24 hours – or 50 km <12 hours.
A continuous 100 km full Ultra Challenge is quite tough, but is absolutely achievable with good preparation, our support teams & rest stops stocked with plenty of food & drink and our ‘Trailmed’ medics.
OR – there’s a 2 day 100 km ‘Daylight’ option with halfway camping as a great way to step up to a full Ultra – and ‘Push Yourself further’!
New to 2024 were ~75 km 3/4 Challenge options on some events if you want to step up from the 50 km!
There’s also a fantastic range of testing single day ~50 km ‘Half’ challenges, scenic ~25 km ‘Quarter’ challenges, a few trail marathons (42 km) – and a range of 10 km taster events.
Young Persons Discount available – if aged 21 or less (subject to min. age rules / distance).
We have a Series of a dozen or so 10 km /10 mile events throughout the season at the main Ultra Challenge venues.
Ideal as a taster event or if you just want a shorter challenge – or to take on whilst your friend or family member is taking on a longer Ultra Challenge.
10 KM / MILE SERIES >>
It only takes 2 to make a TEAM – but the more the merrier! A Team of friends or family can motivate & support each other, whilst sharing an unforgettable adventure with a great reason to celebrate! Teams can do the same or a mix of distances, and sign up with the same or a mix of funding options too.
INDIVIDUALS / SOLO CHALLENGERS will feel 100% welcome & safe and are guaranteed to meet many new friends enroute, and our experienced Support Teams looks after everyone! For 2025 there’s an optional ‘Solo Challenger Start Time’ slot to meet up with others.
Many choose to FUNDRAISE for a charity of their choice, and with 600+ charities to choose from you’ll be amazed how much you can raise on these tough challenges as friends & family will recognise & support your courageous endeavours!
The Ultra Challenge® Series raises £10+ million / year for charities. Choose your charity; set up a JustGiving sponsorship page and make your challenge count!
Others just want a great challenge and SELF FUND their place and achieve something special! There’s a ‘time limited’ PAYMENT PLAN option to spread the cost over 3 instalments.

Full Support ALL THE WAY
An Ultra Challenge® is a special journey. Our unmatched levels of support enables so many to ‘Push Themselves Further’- and whilst a 50 km or 100 km challenge might sound too tough – IT’S ABSOLUTELY ACHIEVABLE! We’ll help you prepare with a Challenge App, training guides & forums. On the day there are camping options, shuttle busses, a warm up & atmospheric send off, a fully signed route, timing & tracking, marquee rest stops, fantastic food & drink included, and expert safety, medical & welfare teams. A big finish line cheer, with a medal, a glass of fizz, a souvenir T shirt, a massage & a finishers meal – it’s a special weekend to remember!
Download our Ultra Challenge® App once you’ve signed up. With guides, optional extras, routes & maps, & the latest updates prior to each Challenge, all the information is at your fingertips.
Our lively Facebook forum is great for advice & meeting fellow Challengers.
If you’re fundraising, your charity sends a support pack & their contact details.
Experienced Challengers help develop our training guides & videos, on foot care, nutrition, hydration, & building distance up for all levels of experience.
We also run a few optional training walks throughout the year to practise night walking and to connect with the Ultra Challenge community.
There are bookable coach transfers, shuttle busses, & parking options before & after your challenge to make travel planning easier.
Most events offer camping packages at the ~50km Saturday ‘half way’ rest stop for the 2 day ‘Daylight’ 100 km challenge option (or for a ‘half’ challenge) and at the main start venue for Friday night before the event.
Pink arrows, and glow-sticks at night mark the route, and with Google route maps in the App you won’t get lost on an Ultra Challenge®!
Our timing system scans you at rest stops, with your progress tracked, and can be shared online. If you want ‘real time tracking‘ to share with family & friends there’s a Geo Tracker hire service.
Our rest stops are the BEST! Covered stops every ~12.5 km or so, and major ones each ~25 km – all with seating, clean toilets, medical services & shuttle busses. There’s a range of snacks & drinks at all stops, with full meals at the ‘major’ ones and the finish, all included in your entry fee.
Ultra Challenge® rest stops will help you get to that finish line!
Rest stops have expert teams supplied by TrailMed, our official medical partner – with doctors, paramedics, first aiders, & podiatrists and massage services provided alongside.
There are emergency response teams with 4×4’s, safety marshals & experienced ‘Trek Masters‘ on the route – with a 24 hr Control Room monitoring all aspects of the event just a phone call away.
An Ultra Challenge® finish line is a celebration, and quite emotional for many after a tough journey!
You’ll get a big cheer, a quality medal, a glass of fizz to toast your success, a visit to the massage tent, and a finishers meal.
Memories will be long lasting, maybe personal goals redefined, and always a great sense of achievement that, once aches & pains subside, will leave you wanting another challenge!
