The Copthorne Races

9 hours

Modelled on the infamous Caesars Camp races, The Copthorne Races take place in Surrey, featuring a wide mix of terrain, woodland and contouring in and around the Box Hill, Mickleham and Headley areas. Indeed, the race name is a play on words as Headley was part of the Copthorne Hundred, an administrative division devised by the Saxons.

The races start at Mickleham Village Hall (Race HQ) with a new improved route of just over ten-mile loops (therefore the 50k consists of 3 loops), providing a cumulative of ascent gained of approximately 2,260 feet per loop. The route will be fully marked on the day with signs & tape.  GPX files available to all entrants below.

As in the 2022 Copthorne Races, we again offer a choice of four distances for the weekend.

50km 6,780ft of ascent with a 9hr cutoff.
50 mile 11,300ft of ascent with a 14.5hr cutoff.
100km 13,560ft of ascent with an 18hr cutoff.
100 mile 22,600 ft of ascent with a 32hr cutoff.

The race, and each subsequent 10.2 mile loop starts at Mickleham Village Hall and heads straight up onto Mickleham Downs. You continue up the “runway” and into the trees at the top. After a short distance a sharp right turn takes you on a gentle decent, which gradually gets steeper and steeper as it turns into the infamous “Kamikaze” hill. Crossing the road at the bottom sees you climbing up towards High Ashurst before a quick decent takes you onto Headley Heath. At the bottom of the decent you encounter the first steps of the loop as you climb again and begin to weaver around the Heath, skirting the main car park. There are several twists and turns around the Heath before you exit via a gate and start a gentle upwards incline past houses on Box Hill. At the top of the road a right turn will take you to Box Hill Village Hall and the halfway Check Point. A loop around the car park (or stop to refill water if needed) and you head back the way you came before turning right and pick up the North Downs Way. A steep decent is followed by a short sharp climb brings you to a lovely gentle runnable decent down to Box Hill Road. Turning almost back on yourself a short climb takes you back to a trail which contours Box Hill below the viewpoint and brings you to the Box Hill steps where you turn left and descend. At the bottom of Box Hill, you bear right and cross the River Mole via the footbridge, before heading to the car park. Turning left there you head down to the river and cross via the stepping stones. You then climb up the Bix Hill steps all the way to the viewpoint, where you turn left, cross the road and head across the Donkey Field. A nice runnable descent brings you to the old tower above Juniper Hall where you do a right turn and take the steps down to Juniper Bottom and then to the car park. Then comes the delight of Satan’s Staircase, a relentless climb back up onto the top of Mickleham Down. Another sharp descent brings you back to Mickleham where you turn right through the graveyard and then at the road, right again and your back at Mickleham Village Hall and the start of another loop.

Mandatory Kit

​•   Primary and secondary head torches or other light sources with sufficient spare battery packs/batteries.
•   Mobile/smart phone with OS Locate installed. A free download from your app store here.
•   Silver foil/survival blanket or survival bag
•   Waterproof jacket (Taped seams preferable)
•   Hydration bladder or bottles capable of carrying at least 1lt of fluids
•   Most importantly of all, a Canary. No Canary, no run. (A fine is payable towards our charity if you wish to race without one)

It was the idea of our Co_Founder, Mark Thornberry. It’s a bit of fun that makes our races a little different. Your canary can be as simple as a printed picture of Tweety-Pie pinned to your race pack, or a giant inflatable. They all count. If you choose not to and incur a fine - it all goes to the Kings College Hospital Liver Cancer Charity in Mark’s memory.

Why Carry a Canary?
