Winsor 50 Challenge


Windsor and Thames path

Take on a 50 km Ultra, a  historic 25 km, or a sharp 10 km challenge – and get active after the Easter break! From our Windsor Racecourse basecamp 2000 adventurers will head out on looped routes through the Great Park with fantastic views of the Castle, on to Runnymede, along the Thames Path, and takes in some wonderful surrounding countryside. You’ll get full support all the way, and a celebration finish back at basecamp. It’s a great way to kick off the Ultra Challenge® season, and start to get in shape for summer.

UK’s #1 series of treks & trail runs for a wide range of ages, fitness & experience levels.. Choose your Challenge – do it at your pace, and there’re 18 events to choose from. Our support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge! There are marquee rest stops, lots of food & drink, medical & massage teams, with a fully signed route & GPS tracking to guide you. A big finish-line celebration awaits with an amazing sense of achievement, and once the aches subside you’ll feel energised, up for more of life’s real challenges – and, maybe, personal horizons redefined!

Whether you’re a walker and new to challenge events, an experienced trekker, a marathon enthusiast upping the distance, or a seasoned ultra runner after UTMB points – there’s an Ultra Challenge® for you! Walk, Jog, or Run at your pace, as an Individual or a Team, for a charity of your choice or just for you.

There’s a NEW Ultra Trailblazerz™ option for ‘rapid runners’, and an Ultra March® option for ‘hasty hikers’ – plus a friendly ‘Solo Challenger’ start time to join up with others. The Windsor 50 Ultra Challenge is fun, safe, & rewarding – with full support all the way, enabling you to push yourself further in wonderful historic scenery – and enjoy a great day out!
