Your Challenge
Your Way!

High quality events to take on at your pace – as a Run, Jog, or even a Walk – or a mix of all! For a wide range of fitness levels, ages & experience – challenge yourself in wonderful British scenery. With full support all the way, camaraderie, and your spirit and determination – you’ll be able to push yourself further than you thought possible!

With 19 running events; numerous distance options; a few 10km ‘tasters’ – and a NEW  TRAILBLAZERZ® category for ambitious runners – there’s an Ultra Challenge® for EVERYONE.

YOUR CHALLENGE – YOUR WAY

An Ultra Challenge® is for EVERYONE – whatever your pace. There are early start time slots for hundreds of runners, with a range of paces, to head out on a clear course.

Many ‘Jog’ – walk a bit / run a bit – and see how it goes over their chosen distance. ‘Cut off times’ enforced on many trail events don’t impact Ultra Challenge® runners, as they’re set for the slowest walking pace – and 50% or more will take the Challenge on as a walk! 

There’s a TRAILBLAZERZ® category for faster, ambitious runners, with an eye on the clock – with trophies, prizes & course records at stake for some.

TRAILBLAZERZ INFO >>
YOUR CHALLENGE – YOUR WAY

100 KM as a continuous Ultra is tough, but absolutely achievable with good preparation, training, and our support. We provide rest stops, plenty of food & drink, and expert welfare & safety teams.

2 Day 100 KM ‘daylight’ option with halfway camping at 50km (or local B&B). Take on 100km without the overnight stretch if you’re ‘jogging’.

75 KM –  option on some events if you want to step up from a 50km Ultra.

50 KM – Ultra distance and a great single day challenge option. Ideal for stepping it up from a marathon or half marathon and to test yourself!

25 KM –  perfect entry point for anyone! A great day out in wonderful scenery with time to celebrate afterwards. The best starting point for a first trail Challenge.

Trail Marathons (42 km) – classic distance choice for many – with 5 available.

YOUR CHALLENGE – YOUR WAY

Most of our events have a 10km /10 mile option based at the main Ultra Challenge venues. Ideal as a ‘taster’ event or first adventure on the trails. Or take on this distance whilst family or friends are taking on  a longer Ultra Challenge!

10 KM / MILE SERIES >>

YOUR CHALLENGE – YOUR WAY

TRAILBLAZERZ® is a category for faster, ambitious runners who start in the first wave and take on the fantastic, fully signed Ultra Challenge® routes, with 100km and 50km options available.

TRAILBLAZERZ® may be seasoned Ultra competitors, regular trail runners, or marathon & 1/2 marathon’ers stepping on to the trails & upping the distance. All will probably have an eye on the clock – some will be out for a personal best – and a few will have a crack at the course records with trophies & prize money at stake

TRAILBLAZERZ INFO >>
YOUR CHALLENGE – YOUR WAY

FOR CHARITY – many support a charity of their choice (600+ are listed). You’ll be amazed how much you’ll be able to fundraise – as friends & family will recognise your ‘ultra’ endeavours! 

Choose a charity; set up a JustGiving page – and make your challenge count!

SELF FUND – others just want a high quality challenge, buy their place online, enjoy it – and achieve something special!

CHARITIES INVOLVED >>

YOUR CHALLENGE – YOUR WAY

It only takes 2 to make a Team! Whilst running can be quite solitary – a Team of like minded friends or family can motivate & support each other, whilst sharing an unforgettable adventure! 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 enroute – and our experienced Support Team looks after everyone!

YOUR CHALLENGE – YOUR WAY

Best value MULTI DEALS for 2 or more Self Fund events, with up to 25% OFF.

We encourage the ‘Young‘ to join – with 20% OFF Self Fund prices for ages 24 or less

Minimum Age Rules –  18 for 100 km & 75 km / 16 for 50 km / 14 for 25 km & marathon / 12 for 1/2 marathon / 8 for 10 km. Under 18’s need to be accompanied by an adult participant.

YOUR CHALLENGE – YOUR WAY

Ultra Challenge® events are fully ITRA-Certified and recognised as UTMB Index races.

Completing a challenge updates your UTMB Index, while ITRA Points provide a standardised measure of race difficulty used across trail running events.

ULTRA supportive
ULTRA sociable ...
ULTRA rewarding!

An Ultra Challenge® provided unmatched levels of support, which enables so many to push themselves further. We’ll help you prepare with an Event App, training guides, and forums.

On the day there are camping options & shuttle busses; a warm up & atmospheric send off; a fully signed route & timing & a GPS App; marquee rest stops with fantastic food & drink (including Ultra-tailored nutrition & SIS energy products); and expert safety, medical & welfare teams. 

Cross the line to a proper celebration: a big finish line cheer; a special medal; a glass of fizz; a souvenir t-shirt; a massage; and a hot meal – All wrapped up in a weekend you won’t forget.

If you’re up for an ultra, make it an Ultra Challenge® 

Pink arrows, pink flags, and glow-sticks at night, mark the route perfectly, and with Google route maps in the App – you won’t get lost on an Ultra Challenge®!

Your progress is tracked at each rest stop with LiveTrail, and with real-time GPS tracking via their app, friends and family can follow along from home.

There are bookable coach transfers, shuttle busses & parking options for before & after your challenge to make travel planning easier. Most Events offer camping packages at the ~50km point and at the main start venue for Friday night before the event.

Our rest stops are the BEST! Covered stops every ~12.5 km – all with seating, clean toilets, medical services & a wide range of snacks & drinks. There’re more substantial meals every ~25km and at 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 therapists. 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. 

Experienced Challengers help develop our training guides & videos delving into topics such as foot care, nutrition, hydration & building distance up for all levels of experience.

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, an optional glass of fizz to toast your success. You can choose to pay a visit to the massage tent, and sit down with a well earned finishers meal.

You’ll take away lasting memories, a powerful sense of achievement, and — once the aches ease — a new desire to take on your next challenge.

Download your Event App once you’ve signed up – with guides, optional extras, and the latest updates. Our lively Facebook forum is also great for advice & meeting fellow Challengers. 

NEW FOR 2026

TRAILBLAZERZ® category for ambitious runners. 100km or 50km in a time goal’ – ascent & gender adjusted for each event – with a 7.0am start.
