UNITED STATES OF AMERICA NORTH CAROLINA — 2025-09-20 — Danbury. "Pilot Mountain to Hanging Rock Ultra & Relay". Don't miss out on this beautiful yet challenging ultra!

UNITED STATES OF AMERICA NEW YORK — 2025-09-20 — Fabius. "Morgan Hill Trail Races & Hill to Hollow 100km". Starting and finishing within Morgan Hill State Forest (camping available), the Morgan Hill Half Marathon and Morgan Hill "Meat Grinder" Marathon courses follow the nearly-all-single-track Onondaga Trail alongside misty ponds, up to incredible vistas, and crossing above waterfalls; past the highest point in Onondaga County on single track mountain bike trails; then back onto the Onondaga Trail to the finish line after running over (or around) the gravestone of one very unlucky guy from the 1700s.The marathon course adds the cruel but beautiful Fellows Hill loop and an out-and-back on the Onondaga Trail to Route 13. With the cooler temperatures and fall colors of late September, this is East Coast trail running at its absolute finest with all the rocks and roots that come with it. The memories will remain with you long after the blisters have healed and the muscle soreness and fatigue have faded. NEW in 2025, SCTR is excited to announce the first-ever running of the Hill to Hollow 100km, co-directed with Pete Dady of the Hash House Harriers who traversed the loop back in the COVID days. Crossing four counties, the course will begin and end in Morgan Hill State Forest (camping available), featuring the same highlights as above before following the Onondaga Trail/North Country Trail east to Highland Forest County Park and past DeRuyter Reservoir, turning south on the enigmatic Link Trail through Muller Hill State Forest before joining the main Finger Lakes Trail in Mariposa State Forest, heading west past Chippewa Falls, and rejoining the Onondaga Trail to reenter Morgan Hill State Forest. This is a VERY challenging 100km and will be more dirt bag ultra than ultra-luxe for this first year, with a commensurate 50% discount reflected in the registration price. Self-sufficiency and strong navigation skills (without 5G/LTE network coverage) are musts, but how many people can say they were part of the birth of an ultra? It takes a tremendous amount of work by a great many people and organizations to provide public access to and maintain the beautiful land and trails upon which these races depend. SCTR is immensely grateful to NYS DEC, Finger Lakes Trail Conference, North Country National Scenic Trail Association CNY Chapter, Highland County Park, the ADK-Onondaga Chapter, and the many private landowners, trail stewards, and volunteers without whom this would not be possible. Please consider making a donation to the FLTC during registration; SCTR will match donations up to $250. Or better yet, become a member at fingerlakestrail.org. www.facebook.com/SaltCityTrailRunning

Those running the marathon and ultra get the added bonus of a trip through the Wicken Fen nature reserve, home to more than 9,000 species, including Konik ponies, cattle, birds and rare plants. This is a low key, friendly event which welcomes adult runners of all ages and abilities. With a few obstacles (steps, stiles, cattle grids etc) along the way, the routes are perhaps better tailored for adventure, fun and stamina rather than PBs. But whatever your pace or goal there'll be plenty of food/drink stations and enthusiastic marshal support throughout. You can access entry details, locations, logistics, course information and past results by visiting the Ely Tri Club web site.

PORTUGAL — 2026-01-15 — Torre. "Terra de Gigantes Ultramarathon". It’s not just another ultramarathon. It’s a long journey between the highest point in mainland Portugal and the Atlantic Ocean, in this case, Nazaré. A journey of astonishment, of encounter, of contact with traditions, but also of faith - without the need to be a believer. It will be a very special time. Crossing a country, in this case, Portugal, from east to west is guaranteed to be a huge journey and an extraordinary experience. The challenge of crossing Portugal from east to west, from the highest point in the country to the beach with the biggest waves in the world, is necessarily for giants. But it’s more. It’s a bit more than effort and glory. It’s courage, management, and a lot of resilience along the paths that take them from the Serra da Estrela to the isolated and beautiful Schist Villages in Lousã.
