Now open for it's 3rd Year - The Hellstone Marathon and Half Marathon - AND 10k RACE - by Badger Trail Events are fully signed, hilly challenging trail races in the Heart of Dorset

We provide great support, medical cover, free car parking, an entry fee that wont break the bank, bag drop, toilets, free hot drinks & refreshment at the finish, medals for all finishers, & 4 aid stations (TBC).

We wanted to give you a slightly different experience to its sister race The Dorset Ooser, and so with The Hellstone Marathon we bring you more devilish hills, more heroic views and more epic skies for a lot of the course, but we couldn't resist including a bit of magical woodland and a stone circle along the way.

We wanted to send you out into the countryside on an adventure but bring you back safely

We wanted to make sure that even if its blowing a hooligan in top of those hills and raining, its also not minus 5 degrees, hence its in May (normally, but this year its October)

The Hellstone Marathon is a qualifying race for the UTMB® (1 point) TBC FOR 2021

Welcome to The Hellstone...



Big Hills, Big Skies, Big Views...

The Races start from the cricket field adjoining the impressive, and beautiful Bridehead House in Little Bredy in the heart of Dorset. 

The routes go straight uphill from the start (where have we heard that before?), then follow windblown hilltops, farm tracks, small footpaths, bridleways, steep fields both up and down, and go past ancient stones,

a forgotten chapel, and a wishing well. Tarmac has been kept to a minimum. Despite the many runnable sections, this race is not easy; The marathon boasts approx 1169m of elevation (and 1 UTMB point), the half comes in at about 614m and the 10k at approx 270m (according to OS maps, full garmin gpx to be provided shortly). 

There are some long and steep climbs, many gates and stiles, and some difficult hillsides to traverse. There are also epic views reaching into the next county in places. 

The Races are pretty much all trail apart from: 
In the Marathon there is a total of approx 3km of short sections of tarmac, the longest being 0.8km
In the half there is a total of approx 1
.2km of short sections of tarmac, the longest being 0.6km
In the new 10km Race there is approx 0.5km of tarmac

There is a generous 8 hour cut off in the Marathon and a 4.5 hour cut off in the half.
There is no cut off time for the 10km.

Routes will be marked with a mixture of tape and our own unique arrows. There will also be marshalls at road crossings and critical junctions. As a back up you will be provided with a gpx file as part of your race instructions.



There will be 4 aid station checkpoints in the Marathon, 2 in the half marathon, and 1 in the 10k.

All aid stations will have shelter and will be well stocked with provisions and all will have the same choice of items (TBC)

PLEASE NOTE THIS IS A CUPLESS RACE - what does this mean? - it means that in line with most european trail races and now many UK trail races we will NOT be providing disposable cups at the aid stations, this is to cut down on both litter and waste. 
Aid station volunteers will be happy to fill your water bladders and bottles for you, but we recommend you obtain a re-usable cup for drinks at the aid stations.  

Something like one of these is ideal:

£3.95 - super light re-usable FOLDING CUP

£7.50 - Hydra Cup 250ml- Xmiles

aid stations will be approximately 8km apart at:


  • TO BE CONFIRMED.....(due to a slight route change) 

 (aid station positions may be subject to change but we will inform you in advance if this is the case)
