UK's biggest & best treks & runs - high quality endurance events for ALL - with 12 unique challenges to choose from.

Over 30,000 will do an Ultra Challenge in 2020, with a wide range of ages, fitness, and experience. Walk, Jog, or Run - with no obstacles, mud, or gimmicks - just trails, hills, and great British scenery. Spirit & determination are needed - and you'll get the best support on any endurance style event - enabling you to go further!

Ultra Challenges are fun, engaging, social, rewarding, and energising with personal boundries often re-shaped. Many link their Challenge with fundraising for a charity of their choice; so far the Series has helped raise over £25 million for good causes.

HALF CHALLENGE ~ 50km  - 1st or 2nd Half - suits many - and don't forget it's longer than a marathon! Also ideal to join up with a 100km challenger friend for the 2nd Half.


QUARTER CHALLENGE ~25km - perfect as a 'starter' Challenge - and gives you time to celebrate in the evening! Also good for supporting a 100km / 50km Challenger on their first leg.
