Event overview

From the 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.

The Ultra Challenge Experience

This challenge is part of the UK's number one series of trek and trails runs for a wide range of ages, fitness and experience levels.

Choose your challenge and do it at your pace. The level of support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge. There are marquee rest stops, lots of food and drink, medical and massage teams, with a fully signed route 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.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
