As each round is 6.7km long you can run any distance between 6.7km and 100miles or any time between 1 hour and 1 day.

UNITED KINGDOM ENGLAND — 2026-10-18 — Ely. "Ely Tri Club Runfest". Returning for 2026 the Ely Tri Club Runfest offers a choice of distances ranging from 10k to 66k, all of which start and finish at the iconic 11th century cathedral before taking in more of the beautiful historic city of Ely and heading out into the Cambridgeshire countryside. Most of the course involves quiet, flat, traffic free paths along the banks of the rivers Great Ouse and Cam and their adjacent fens (there's only one short, gentle climb through Cherry Hill Park in the entire race). 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 (www.elytriclub.co.uk).

The course is laid out in the heartland of Indian coffee in the Malnad region of Karnataka at elevations from 3000 to 4500 feet. In a way, The Malnad Ultra is not designed as a race per se. We think that the runners will take time for selfies, listen to the leaves rustle, the cicadas chirp and the birds sing. Massive jungle trees, thousands of silver oak trees and endless coffee plantations will catch your attention. With some luck, you will sight small wildlife like monkeys, porcupines, peacock, hares, giant squirrels, civet cats and snakes.

CAPE VERDE BOA VISTA (CAPO VERDE) — 2026-12-05 — Sal Rei. "Boa Vista Ultra Trail". The event gives competitors a choice of three courses: the 150-kilometre Ultramarathon which takes them around the periphery of the island, the 75-kilometre Salt Marathon which has its finish-line in one of the island’s last-remaining salt pans, and the 42-kilometre Eco Marathon which takes athletes through unspoilt nature encompassing both ocean and desert scenarios. The three courses all share the same unique backdrop and constantly changing terrain: dirt tracks that turn into desert dunes, stony ground that eventually becomes proper road. Runners will be completely unaided throughout because in addition to competing against the clock and the rest of the field, they will also have to grapple with the island’s wild landscape and, of course, their own endurance levels. All in all, this is an event that leaves its mark. Boa Vista is the nearest of the Cape Verde islands to the African mainland and, with a population of just over 12,000, is one of the last-surviving unspoilt paradises. This event also offers the perfect opportunity to encounter the authentic nature of this beautiful area – its desert, salt pans, ocean, tiny villages and idyllic landscape are completely unique. www.boavistaultratrail.com

PORTUGAL — 2027-01-13 — 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. It’s paths of faith around Fátima Sanctuary that will take you to the magnificent and gigantic waves of Nazaré. It will be at the beginning of winter and, traditionally, a time of very low temperatures and rain. Starting at the highest point in Portugal means beginning the challenge with negative temperatures and, who knows, snow. It’s this set of factors, associated with the distance and unevenness, that will make you a giant. www.horizontes.pt/en/terra-de-gigantes

ARGENTINA BUENOS AIRES — 2027-07-11 — Villa Epecuén. "Vuelta al lago Epecu". [Spanish] La Vuelta al Lago Epecuén es una carrera de ultra distancia, con 60 kilómetros de terreno técnico pero sin grandes desniveles. La costa del lago tiene barrancas, arena, suelo salino, arroyos, bosques de caldenes y campo, algunos caminos vecinales y las famosas ruinas de Villa Epecuén. Sin embargo la convocatoria no está abierta sólo para ultramaratonistas y aventureros de la larga distancia, habrá otros 2 circuitos de 21 y 10 kilómetros respectivamente (las distancias son aproximadas y variables según el clima y estado del terreno). Todos los circuitos correrán entre las ruinas del pueblo que se inundó en 1985 y que, en los últimos años, volvió a emerger y ahora es Patrimonio Histórico de la Provincia de Buenos Aires. La carrera en el Lago Epecuén tiene su origen en la idea de resignificar el pasado para unirlo con un presente próspero. Correr entre las ruinas de lo que fue una villa turística es una experiencia transformadora, tanto para el corredor, como para el lugar. Es correr en medio de la historia. Por eso, encarar la Vuelta al Lago para pasar por las ruinas y retornar a la ciudad tiene un doble significado: saber que el hombre siempre puede cuando se lo propone, y que el futuro es un camino que se construye con voluntad. Volveremos a dar la Vuelta al Lago Epecuén, volveremos a dar la vuelta a la historia. www.vueltalagoepecuen.com
