The Ultra Challenge Series is one of the UK's largest challenge event series, with over 35,000 participants taking part each year, and raising over £7 million for good causes. We work with over 800 UK charities, who promote the events to their supporters, encouraging them to "Walk, Jog, or Run" a distance of their choice. Charities who promote the Series will typically see a 7:1 ratio of income vs costs - a fantastic return on investment!

With 18 great events coming up in 2025, there is more opportunity than ever for charities to generate unrestricted income through our popular challenges.

This Charity is your main hub - whether you are a New Charity looking to get involved in the Series, or an existing charity looking for Assets you can use to promote the Series.
