Join the Ultra Challenge® Series in 2026!.
Are you thinking about joining an exciting adventure? The Ultra Challenge® Series is a fantastic way to challenge yourself while supporting a good cause. You can walk or run distances like 100 km or 50 km, and the best part is you can do it while helping a charity. Signing up is easy! Make sure to choose your challenge wisely and consider if you want to self-fund your registration fee or support a charity.
Once you decide on your challenge, you need to fill out a registration form. You can sign up for different distances like 10 km, 25 km, or even up to 100 km. If you’re under 18, make sure to have an adult with you to register. You’ll get an email with all the details after you sign up, so keep an eye on your inbox! Plus, if you're planning to join multiple challenges throughout the year, be sure to check out the Multi Deal which can save you a lot of money!
