Event Information

Hardassnails is a Mid-Summer Night’s Dream Trail Run

Congratulations, you’ve found an excuse to sneak an extra race into your calendar – only this time it won’t affect your weekend plans… Come and experience our multi-award winning midweek trail run – which we’re told is best celebrated with a sunset Aperol Spritz from our Horsebox Gin Bar… we’re game if you are! A popular choice for those who like to squeeze an extra run in after work, this sell-out event offers challenging chip-timed 5km, 10km, 15km Trail Runs and a 2km Kids Run. All events proudly showcase some of the most spectacular scenery offered by the Surrey Hills Area of Outstanding Natural Beauty; setting off along the Pilgrim’s Way over the North Downs, runners continue across to Newlands Corner, weave through the majestic Chantries Woodland and climb the breathtaking (but rewarding) incline to the peak of Surrey’s 18th highest hill – St Martha’s – where it is possible to enjoy panoramic views of up to 7 counties.

All participants are rewarded with a large snail medal and homemade cakes – made by aat’s very own Aunt Debbie – and can enjoy free sports massage courtesy of Fitstuff Clinic and Runlab.

I love the snail medal – it’s my favourite!

I’m usually the tail runner for this run – I love keeping everyone at the back of the pack motivated and happy. Looking forward to seeing you all there.
