'Britain's toughest 10k'!

The 'substantially harder' route for the Knacker Cracker race, from 1 January 2025. Not running down the Burford Spur slope, but instead using the old military road. Also, this now does not run up to Juniper Top (too ecologically sensitive) - but instead goes up the bottom of Happy Valley (which should perhaps be renamed 'Unhappy Valley.' It just gets steeper and steeper!

Kids' fun run, the Nipper Knacker; Ladies most welcome for the ladies' race - the Knicker Knacker, while men will feel a punishment in their gonads, during the Knacker Cracker!

The route is exactly 10.000km and includes ascent of 473m and descent of 335m.

Sorry, earphones/headphones not allowed on the course - don't run in a bubble!

If Box Hill is not available for any reason, we will be using the Knacker Cracker 'B' Course, around Denbies Vineyard. Still a tough course!

The Knacker Cracker was voted Britain's best trail race in 2012 and 2013 and was voted Britain's best 10k in 2008, 2009 and 2010 by runners voting at Runner's World

Entries after 8pm on 1 December will not have their names on the race t-shirts, due to production deadlines - sorry!

Parking and registration area at Denbies Wine Estate, and race start at the BOTTOM of Box Hill. NO PARKING AT THE TOP OF BOX HILL! After the race, you will need to walk back to your car at Denbies.

(normally...) A run for hearty man fellows and lady fellows, mostly on rough tracks, and including superb views over the North Downs, the Mole Gap, Denbies Vineyard, and Dorking.

Wishful thinking weather forecast: warm and sunny. (actual weather forecast)
