Ultra Challenge Series 2026

Take on an unforgettable challenge in the great outdoors – perfect for individuals and teams alike

Whether you’re a first-time walker, a seasoned trekker, or even an experienced runner looking for your next big challenge, the Ultra Challenge® Series has something for everyone. With 20 incredible events across the UK, each with its own unique character, you’ll find the perfect challenge to suit your pace, experience, and goals.

Imagine taking on stunning coastal paths, historic river routes, or scenic countryside trails, all while raising funds to help Dreamflight create magical, life-changing adventures for children. Most participants walk at a pace that suits them, many jog parts, and some run the full course Ultra Marathon style. You can join as an individual or as part of a team and every step you take will make a difference.

Choose from:

  • Epic 100 km challenges (continuous or with camping at halfway)
  • 50 km, marathon, and 25 km options
  • 10 km taster events for those who want a shorter challenge

Every event is fully supported with rest stops every 10–15 km stocked with drinks, snacks, and hot meals. Routes are fully signed, there’s a Challenge App and GPS tracking, medical and welfare teams, and a huge finish-line celebration with a medal, glass of fizz, and a special finisher’s t-shirt.

Taking on an Ultra Challenge® for Dreamflight isn’t just about the miles, it’s about making a real difference. You’ll enjoy breathtaking scenery, meet amazing people, discover your inner resilience, and cross the finish line with an overwhelming sense of achievement. With some training, determination, and our support, anyone can take on an Ultra Challenge®.

Ready for an adventure? Explore the challenges below and take on a journey that makes a real difference. Every mile you conquer helps create magical memories for Dreamflight children. Which one will you choose?
