2nd edition of Styx Race, at the Kalavryta Ski Center on Mount Chelmos. Two-day trail running festival with five distances for all levels, from the technical 30km down to the free kids race. Race Village at the ski center hosts registration, starts, finishes, awards and sponsor stands; the chairlift runs continuously over the weekend for spectators and support crews. 20% discount for registrations completed by 23 August 2026 with code styx20. Point-to-point vertical ascent finishing at Neraidorachi (2,340m) — up from roughly 3km/700m gain in the 2024 edition. Continuous climbing with minimal recovery sections and increasingly open terrain near the top; return to the Race Village is by chairlift.
