Saturday 30th April 2022

We’ve been asked why this event is 110 & not 100 miles?
It’s because our races go up to 11…

8am Start for the Solo & the relay with a 34hr cut-off for the event.

Mickleham Village Hall, 20 Dell Close, Mickleham, Dorking, Surrey RH5 6EE.

As per all of our events, we encourage car sharing between runners. The car park only has capacity for 50 cars.

The races start at Mickleham Village Hall (Race HQ) and will involve four loops varying between 26 & 31mile distances. The majority of each loop will be on the trail with short sections on pavements & along roads. The hall will be the main checkpoint with runners having access to their drop bags at the end of each loop, along with tea, coffee & various foodstuffs.

The hall will also act as the changeover point for the relay teams. Each team will consist of four runners each running a leg of the race.

All runners will have a tracker & a timing chip attached to them. The relay teams will share the one tracker so they will have to make sure that it is attached to their team-mate before they head out on the next leg. The trackers are your responsibility & loss of them will incur a replacement charge of £100. Each runner should aim to be totally self sufficient on each leg but we will have a water station at roughly the half way point of each section.

The route will be marked on the day with signs & tape, with the GPX files available to all entrants two weeks before race day.

Due to permit regulations, all runners must be aged 20yrs or older on race day.


The Village Hall will be well stocked with the ‘usual’ ultramarathon nutrition. A water point at roughly the halfway point on each section.

Entry Fees

Solo entries £100
Relay entries £120 (team of 4)

Trophies for first male & female in the Solo category & first team in the relay. Finishers awards for everyone who makes it to the end.

A special “Thorners” trophy will be awarded to one entrant in the race.

**All profits for this event will go towards Liver Cancer Research at Kings College Hospital**

The Thorners 110.

A race to celebrate the life of Mark Thornberry.

On the 15th June 2020, Mark lost his fight against Liver Cancer after a three year struggle following his terminal diagnosis in 2017 when he was only given six months to live. He crammed an enormous amount of living into those three years making fabulous memories with his family & friends & also ran the GUCR 145mile race from Birmingham to London, the Javelina Jundred in Arizona & the Bello Gallico 100 miler through the Ardennes Forest in Belgium. We’re hoping that the routes on each section gives the sting in the tail that Mark liked to give when he planned the Canary Trail routes for the Headtorch Marathons.

We hope that you have fun & enjoy it. 

The woods are lovely dark & deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
