THE '10' SERIES

10 KM / MILE challenges

Throughout The Season

Alongside Ultra Challenges we have 10 km or 10 mile events for those looking for a shorter challenge, perhaps experience a ‘taster’ to see what an Ultra Challenge set up is all about, or get active whilst your partner or family member is taking on a longer Ultra! On most you can Walk, Jog, or Run (some are just walks) – and they’re ideal to also get your family, children, and friends involved with – to get active, and have a great day out! 

Your Challenge, Your Way!

A 10 km or 10 mile challenge is fun, safe, and accessible, rewarding! You can take it on at your pace as an individual, or as a team of friends or family – and children are welcome, there’s an optional finishers meal (picnic included on some) – and you’ll enjoy a great day out! Scroll down to see the events – they’re in date order
