The Windsor 50 Ultra Challenge®

On 18th April, the Windsor 50 Ultra Challenge hosted more than 2,000 Challengers across 50km, 25km, and 10km routes. Whether it was a walk, jog, or run, every participant pushed themselves further and achieved something incredible.

The fast and flat course took participants along the Thames Path, down the Long Walk right up to Windsor Castle, and through stunning countryside – ideal terrain for setting PBs and enjoying a day out in the sunshine.

Standout Stories

Every participant has an important reason for taking on an Ultra Challenge. Some highlights from the Windsor 50 include 50km runner Jonah, who finished in 6:08:30 just 11 months after two heart surgeries.

Chloe, fundraising for the Firefighters Charity, also completed 50km spectacularly dressed as a fire engine – we thought it was difficult enough in regular walking clothes!

Let us know why you’re taking on your Ultra Challenge on the day of your event – keep an eye out for the content team and we’ll be sure to feature you in our coverage.
