What's an Ultra Challenge

 Your Challenge,Your Way!


2019 Divider 699

Endurance style events for ALL!

Over 20,000 adventurers will take on our 9 Ultra Challenge events in 2019 - with a wide range ages, fitness levels, and experience - all with a goal to push themselves further. Walk, Jog, or Run it - and you'll receive the best support available on any UK event all the way to your finish line.

Ultra Challenges are fun, engaging, even life changing for some with personal boundries re-defined - and you'll meet lots of new friends on your journey. Many choose to link their Challenge with a charity of their choice to support a special cause, or to help others who may face tougher challenges in their life. The 2019 Series will help to raise over £5 million for UK charities.

Join us - and you'll be amazed at what's achievable when you dig deep!

 100km, 50km, or 25km

Sliver Test


100km or 50km sounds so far! It is tough - but achievable - and so far over 55,000 people have done an Ultra Challenge. There's 9 fantastic Events for 2019 - choose the Challenge & distance that's right for you - prepare well - dig deep - and we'll support you all the way!

FULL 100km CHALLENGE - you just keep going - day & night if required - with Rest Stops en route with cover, seating, food, toilets, & medical services


2 DAY 'DAYLIGHT 100km' -  with a half-way break / sleep - including a camping option 


HALF CHALLENGE ~ 50km  - 1st or 2nd Half - suits many who are new to the world of Ultras -  and remember it's longer than a marathon! Also ideal to join up with a 100km challenger friend for the 2nd Half together.


QUARTER CHALLENGE ~25km - perfect as starter Challenge for many - and gives plenty of time to celebrate in the evening! Also ideal if you're supporting a full distance Challenger on their initial leg.


NEW TRI CHALLENGE - take on 25km first, then choose 50km on a different event, and finish your season with a full 100km challenge. Check out our great value 'MULTI EVENT DEALS'.


Whichever Challenge you choose, you can sign-up as an INDIVIDUAL and meet others along the way - or as a TEAM and help each other!


 Walk it, Jog it, or Run it

- 50km Half Challenge: 7-10 hours

- 25km Quarter Challenge: 3-4 hours

- 50km Half Challenge: 4-7 hours
- 25km Quarter Challenge: 2-3 hours

We help you prepare

Training Walk 699x200


Whether your goal is a sub-24 hour 100km walk, or, as is very common, just to complete the Challenge distance - good preparation is the key. Sign up for an Ultra Challenge and you'll get:


Challenge APP - all the info at your finger tips on your mobile.


Training Plans - suggested time-lines to work to - and pre-challenge milestones.


Training Walks & Runs - we organise optional days & weekends, and it's a great way to meet our team, test your kit, and get in shape! 


Kit Lists - the App and the website Participant Area have all the details.


Preparation Videos - a series from our 'expert panel' - covering the important topics - including feet, nutrition, training, and kit.


You can always try a shorter distance first - 25/50km - and use it to build up to your 100km challenge later in the season.
