It’s true to say our always popular Country to Capital Ultra attracts a global field, with some of the best runners in Britain and beyond racing the 43-mile course.
This famous race is the curtain raiser for the ultra running season – and the starting point for those brave Go Beyond runners wishing to take on our Grand Slam of four ultra marathons over 180 gruelling miles.
Country to Capital takes you through the Buckinghamshire countryside, crossing the M25 – by bridge of course! – and heading towards the well-heeled surroundings of Denham. From there, runners pick up the Grand Union Canal towpath for the final run into London.
The finish is near the Little Venice canal basin, a surprising tranquil setting in the heart of the capital and close to both Paddington and Royal Oak Tube stations. The race concludes at The Stowe Centre, where you can enjoy showers, toilets and a large hall to relax in after finishing.
This is the start of our Grand Slam journey – anyone who wants a real challenge can click on the link on the right hand side of this page to book their place. Our Grand Slam includes not only Country to Capital but the Rose of the Shires, Shires & Spires, and Thames Trail Ultras. This is a truly incredible running opportunity, and you can take advantage of our offer to pay in three installments at no extra cost.
Country to Capital is historically a sell-out event, so be sure to get your entry in early. It is fully tracked and interactive, allowing your friends and family to follow your progress from the comfort of their armchairs. You can also make sure that you are following the route correctly!
