Course Maps & GPX

Conquer Old El‑Diablo!

El Diablo is Jersey’s rugged north‑coast challenge — two distances, one unforgettable journey.

Starting from Les Platons at 9am (Half Marathon) or Crabbe at 10am (10k), the course plunges down to Bonne Nuit Bay and Grève de Lecq, before climbing steeply back onto the clifftop paths. From here you’ll take in Sorel Point, the majestic Mourier Valley, and Devils Hole, with leg‑burning climbs and quad‑smashing descents to test your grit.

As you push on, the trail rolls out past Plémont Bay and Grosnez, before opening up across the wild headland towards L’Etacq. The final stretch brings a welcome downhill to the finish, where our team will be waiting with hugs, cheers, and your hard‑earned medal.

Your entry includes a race T‑shirt, medal, insurance cover, a fully marked course, and water, Coke and treats at the aid stations and finish. Whether you take on the Half or the 10k, you’ll be part of an ever‑growing, supportive Trail Monkey community — and you’ll have conquered Old El‑Diablo!

FAQs

Do I really need trail shoes?

Yes — the north coast is technical and can be slippery in the wet. Trail shoes are essential.

Are all items on the kit list really needed?

Yes. Weather changes quickly on the cliffs. The kit list is part of our duty of care.

Is there a cut-off date for entry?

We allocate 60 places for the half and 40 for the 10km. We buy these many medals bespoke to each distance, so once places are full we cannot accept any more entries.Furthermore the T-Shirt order deadline is about 3 weeks before the race date, after this date your chance of getting a t-shirt diminshes as we order to quantity entered on the date of order. Get in quick as we always sell out!

Is the course marked?

Yes. We mark every decision point with arrows and barrier tape. Still, please review the GPX/map if you’re new to the area.

What food & drink are at checkpoints?

Water, Coke and sweets at the aid station. Please bring your own cup to reduce single‑use plastic.

Is there a cut‑off?

Half: 4 hours. 10k: 2 hours. We welcome all abilities and apply common sense on the day while prioritising safety and volunteer welfare.
