It's Your Challenge
Your Way!

Endurance style events at your pace – for a wide range of fitness levels, ages, and experience – for teams and individuals – for a charity of your choice, or just do it for yourself. There are no obstacles or mud pools – just trails, wonderful British scenery, full support, camaraderie, and your spirit & determination. With 14 events and 3 distance options – there’s an Ultra Challenge® for everyone in 2021.

Your challenge – at your pace! Most will walk – but many ‘jog’ and may run a bit, walk a bit, and see how it all goes. At the front runners might be stepping up from a marathon distance, or testing themselves against the clock – with some out for UTMB points.

A ‘continuous’ full 100 km is tough, but is achievable with our support. There’s a 2 day 100 km ‘Daylight’ option with half way camping, 50 km ‘half’ challenges, and 25 km ‘quarters’. For 2021 we’ve a few 10 km ‘taster’ options – and also ‘Virtual Versions’ of each Ultra so friends & family can join in. 

It only takes 2 to make a Team! A Team of friends can motivate each other, share an unforgettable adventure, with a great reason to celebrate afterwards. Individuals will meet new friends en-route, and our Team is there to look after everyone!

Many fundraise for a charity of their choice – you’ll be amazed how much you can raise, as friends & family will recognise & support your endeavours. The 2021 Series will help raise £7+ million. Equally, others just want a great challenge – and Self Fund their place.

For some, one event is not enough. We’ve best value ‘Multi Deals’, including the ‘Tri-Challenge’ which sees you start with a 25 km, then 50 km on another Event, and finish with a full 100 km challenge. 

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

Looking for a great event without the hassle of organising it? Get your Team energised & bonding again on a fun, accessible, safe, high quality event. With optional hospitality packages – make an Ultra Challenge your company’s special event in 2021 – maybe supporting your ‘charity of the year’.

Fully Supported
All the Way

We’ll help you prepare for your Ultra Challenge® – with an App, online guides, forums, and training walks. On the day there’s Covid-safe venues, camping options, a noisy send off, a fully signed route, chip timing, marquee rest stops, fantastic food & drink, and expert medical & welfare teams. It’s a big finish line cheer, medal, glass of fizz, massage, BBQ, and a weekend to really remember!

Download the App once you’ve signed up – with maps, guides, extras booking, and the latest updates. Our Facebook forum is great place for advice and meeting Challengers. If you’re fundraising, your charity sends you a support pack, contact details & procedures.

Experienced Ultra Challengers help develop our training guides, on – foot care, nutrition, hydration, & building distance up for all levels of experience. We also run optional training walks, and for runners sessions with an Ultra coach.

There are bookable coach transfers and shuttle busses before & after your challenge to make your travel plans a bit easier.  Most Events also offer camping packages at the 50 km ‘half way’ of the challenge, and sometimes at the start venue beforehand.

Pink arrows, ribbon, & glow-sticks at night, mark the route, and with Google maps in the App – you won’t get lost! Our chip timing has you scanned at rest stops, with your progress tracked, and can be  shared online for family & friends. 

There’re Covid Secure covered rest stops every 12.5 km, with major stops each 25 km, with seating, clean toilets, medical services, & shuttle busses. There’s a range of snacks & drinks at all stops, with full meals at major ones – all included in your entry fee.

All rest stops have expert medical teams, including, doctors, paramedics, first aiders, podiatrists, and massage services. There’re emergency response teams, safety marshals & Trek Masters on the route, and a 24 hr control room just a phone call away. 

The finish line is a celebration, and quite emotional for many after a tough journey. You’ll get a big cheer, a medal, a glass of fizz, a visit the massage tent or foot clinic, and a welcome BBQ. Memories will be long lasting – and perhaps your goals redefined.
