Trois distances nature figurent au programme de la même journée, avec des départs échelonnés du plus long au plus court : 65 km (40 miles) à 8 h, 32,5 km (20 miles) à 9 h et 17 km (10 miles) à 10 h. Aucun dénivelé officiel n'est communiqué pour ces parcours.\u003C\u002Fp>\u003Cp>La progression des formats permet de choisir son engagement sans changer de rendez-vous. Le 17 km convient à un coureur habitué aux sorties longues sur sentier qui veut découvrir la course en montagne galloise ; le 32,5 km demande déjà une habitude des efforts de trois à quatre heures ; le 65 km relève de l'ultra et suppose un cycle de préparation spécifique, avec des sorties longues enchaînées le week-end et un travail de descente. Une échéance de début mars implique de construire son volume pendant l'hiver, avec un matériel adapté à un terrain potentiellement gras et à une autonomie longue.\u003C\u002Fp>","fr",[23],[],[],{"lat":28,"lng":29},51.876835,-3.106125,{"year":31,"number":9,"firstYear":9},2027,[],[34,37,40],{"name":35,"distanceFormatted":9,"distanceMeters":36,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"40 miles",65000,{"name":38,"distanceFormatted":9,"distanceMeters":39,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"20 miles",32500,{"name":41,"distanceFormatted":9,"distanceMeters":42,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"10 miles",17000,[44,53,63,72,82,91],{"permalink":45,"name":46,"startDate":47,"city":48,"distances":49,"distanceKm":51,"ficheLocales":52},"trails-tarmac-back-yard-ultra-winter","Trails & Tarmac Back Yard Ultra - Winter","2027-02-06","Llangattock",[50],"1 h",3,[],{"permalink":54,"name":55,"startDate":56,"city":57,"distances":58,"distanceKm":61,"ficheLocales":62},"epona-100","Epona 100","2027-05-08","Llanfoist",[59,60],"100 mi","100 km",8,[],{"permalink":64,"name":65,"startDate":66,"city":67,"distances":68,"distanceKm":61,"ficheLocales":71},"beast-of-the-beacons-ultra-40m-plus-20m-10mile","Beast of the Beacons Ultra 40m plus 20m & 10mile","2027-04-17","Llangynidr",[69,70],"16.09 km","32.18 km",[],{"permalink":73,"name":74,"startDate":75,"city":76,"distances":77,"distanceKm":80,"ficheLocales":81},"beacons-marathon-and-ultra-2026","Beacons Marathon and Ultra","2026-11-09","Talybont-on-Usk",[78,79],"73.7 km","43.3 km",13,[],{"permalink":83,"name":84,"startDate":85,"city":76,"distances":86,"distanceKm":80,"ficheLocales":90},"beacons-ultra-and-trail-marathon","Beacons Ultra and Trail Marathon","2026-11-07",[87,88,89],"21.1 km","41.8 km","75.6 km",[],{"permalink":92,"name":93,"startDate":94,"city":76,"distances":95,"distanceKm":98,"ficheLocales":99},"midnight-mountain-marathon","Midnight Mountain Marathon","2027-06-12",[96,97],"26.2 mi","13.1 mi",15,[]]
