Our Cirencester basecamp is the start of the 100 km looped route through the heart of the Cotswolds, providing a stunning setting for 2,000 adventurers to test themselves – so join the Bright Horizons Team and fundraise for Bright Horizons Foundation for Children. Rolling hills, villages, the Cotswold Way, footpaths & trails, with some fabulous views en route. You’ll get full support & hospitality, including optional ‘university style’ accommodation at basecamp, and with three quarter, half, quarter + a Cirencester 10 km distance option also – there’s a Cotswold’s Challenge for everyone.
Choose your Challenge, support your charity – do it at your pace, and there are 20 events in the Series with distance options to suit all! The ‘famous’ Ultra Challenge support enables you to go further, whilst enjoying the great outdoors & camaraderie. There are marquee rest stops, lots of food & drink, medical & 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, and up for more of life’s real challenges!
Good preparation & smart planning are key, and from the moment you sign up you’ll have access to our Challenge App – with training guides, optional training walks, maps, online forums, and the latest news & updates.
Rest Stops every ~12.5 km with ‘major’ ones every ~25 km, and are much more than the shaky gazebo with water that you see on some events. We’ve marquee cover, large medical & welfare tents, catering services, seating areas for recovery, changing rooms, and a friendly welcome!
There’re pink arrows to guide you, distance markers, glow-sticks at night, hazard signs, and a route map in the App. Our ‘Trek Masters’ organise group departures at night so nobody has to walk solo. Our chip timing system enables our Control Room, and your friends / family, to track your progress through the Rest Stops.
Keeping you well fed & hydrated is key. We pride ourselves on the quantity & quality of our catering, and meals, snacks & drinks are included!
We’ve experienced Doctors, Paramedics, First Aiders, Podiatrists, and Massage Teams at Rest Stops. There’re ‘Self Help’ areas with blister plasters, talc, Vaseline, and tape if you want to patch your own feet. Our mobile Emergency Medical Teams are only a phone call away, via our 24 hour Control Room
We don’t want you to forget that finish-line moment – our Cheer Squad will ensure you won’t! You’ll get a medal, finisher’s T-shirt, and a glass of fizz, before heading to a BBQ and a well earned rest. Download your official Challenge certificate when you’re ready.
There’re shuttles to local train stations for onward travel, and most finish lines have parking so supporters can meet you. We’ve bus ‘transfers’ to / back to key venues (eg the start) – and check out the ‘Bookable Extras’ for details of all transport options.
Whether you’re a walker and new to challenge events, an experienced trekker, a marathon enthusiast upping the distance, or a seasoned ultra runner – there’s an Ultra Challenge® you! Walk, Jog, or Run at your pace, as a member of the Bright Horizons Team. The Cotswold Way Ultra Challenge is fun, safe, & rewarding – with full support all the way, enabling you to push yourself further in wonderful coastal scenery, and enjoy a great weekend away.
