It's Your Challenge
Your Way!

High quality endurance style events to take on 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 British scenery, full support all the way, lots of food & drink, camaraderie, and your spirit, determination & sense of adventure! With 14 events, 3 distance options, and a few 10 km ‘tasters’ – there’s an Ultra Challenge® for everyone!

Your Challenge – Your Way! Most walk, but many ‘jog’ so may run a bit, walk a bit and see how it goes! At the front ‘runners’ may be stepping up from a marathon distance, testing themselves against the clock, or out for ‘UTMB’ qualifying points.

A ‘continuous’ 100km full Ultra Challenge is pretty tough, but absolutely achievable with good preparation, our support teams, and rest stops stocked with plenty of food. Or – there’s a 2 Day 100 km ‘Daylight’ option with half way camping as an alternative. There’s also a great range of testing single day 50km ‘Half’ challenges, scenic 25km ‘Quarter’ challenges. and a few 10 km ‘Taster’ options.

It only takes 2 to make a Team – but the more the merrier! A Team of friends 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. Individuals will meet many new friends en-route – and our experienced Team looks after everyone!

Many fundraise for a charity of their choice, and you’ll be amazed how much you can raise, as friends & family will recognise & support your ‘tough’ endeavours. The Series raises £7+ million / year for UK charities. Others just want a great challenge – Self Fund their place – and achieve something special. There are discounts for ‘young persons’ (18 and under) as we’re keen to get them active! 

 There’s also best value ‘MULTI DEALS’ for 2 or more events – with up to 30%+ OFF!

We want to encourage the ‘YOUNG’ to join – so there’s 33% OFF for those aged 18 or less (subject to event distance rules).

If you have ambitions of competing in the famous ‘Ultra Trail du Mont Blanc’ event – an Ultra Challenge® is perfect to clock up ‘qualifying points’. Full Challenges (~100 km) have 3 or 4 points available & Half Challenges (~50 km) from 1 – 3 points.  

Looking for a great event for your team without all the hassle of organising it? These events are PERFECT! Your Team will be energised, exercised, bonding, and motivated on a fun, accessible, safe, high quality outdoors event. With optional hospitality packages available –  you can make an Ultra Challenge® your company’s special event in 2023 – maybe supporting your ‘charity of the year’.


Alongside the ‘Real Challenges’ there are parallel ‘Virtual Versions’ of each Ultra Challenge®, enabling friends, family, and anyone else to get involved – or to help you train & get in shape. A great way to boost your fundraising network if you’re supporting a charity – or to get many more colleagues involved & active if you’re a company


Download our Ultra Challenge® App once you’ve signed up – with guides, optional extras, and the latest updates; there’s also an ‘event specific’ app available prior to each Challenge – with the final details.  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 – and for runners, bookable sessions with an Ultra coach.

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’ 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 chip timing 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 our new 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 medical teams, with – doctors, paramedics, first aiders, podiatrists, & massage. There’re emergency response teams, 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 a great sense of achievement that, once aches & pains subside, will leave you wanting another challenge!

Full Support

An Ultra Challenge® is a journey. We’ll help you prepare with an App, online guides, forums, and training material. On the day there’re  camping options, shuttle busses, a warm up & noisy send off, a fully signed route, chip timing, 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 – and a it’s weekend to remember!
