El Diablo is Jersey’s rugged north‑coast challenge — two distances, one unforgettable journey.
2 races
Event overview
Starting from Les Platons for Half Marathon or Crabbe for 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!
