Trois distances partent en décalé : l'ultra de 40 miles, soit 64,4 km, à 8 h, le 20 miles (32,2 km) à 9 h, puis le 10 miles (16,1 km) à 10 h.

Le 10 miles constitue une découverte accessible pour un coureur habitué au 10 km sur route, moyennant des chaussures adaptées au terrain gallois. Le 20 miles s'apparente à une sortie longue exigeante, utile dans une préparation d'ultra. Quant au 40 miles, il demande un cycle spécifique de plusieurs mois, un ravitaillement testé et l'habitude de gérer plusieurs heures d'effort par temps changeant.\u003C\u002Fp>","fr",[23],[],[],{"lat":28,"lng":29},51.8687319,-3.2269901,{"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},"20 Mile Trail Running Challenge",32180,{"name":38,"distanceFormatted":9,"distanceMeters":39,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"10 Mile Trail Running Challenge",16090,{"name":41,"distanceFormatted":9,"distanceMeters":42,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"40 Mile Ultra Challenge",64360,[44,54,63,72,81,92],{"permalink":45,"name":46,"startDate":47,"city":48,"distances":49,"distanceKm":52,"ficheLocales":53},"beacons-marathon-and-ultra-2026","Beacons Marathon and Ultra","2026-11-09","Talybont-on-Usk",[50,51],"73.7 km","43.3 km",5,[],{"permalink":55,"name":56,"startDate":57,"city":48,"distances":58,"distanceKm":52,"ficheLocales":62},"beacons-ultra-and-trail-marathon","Beacons Ultra and Trail Marathon","2026-11-07",[59,60,61],"21.1 km","41.8 km","75.6 km",[],{"permalink":64,"name":65,"startDate":66,"city":67,"distances":68,"distanceKm":70,"ficheLocales":71},"trails-tarmac-back-yard-ultra-winter","Trails & Tarmac Back Yard Ultra - Winter","2027-02-06","Llangattock",[69],"1 h",6,[],{"permalink":73,"name":74,"startDate":75,"city":48,"distances":76,"distanceKm":79,"ficheLocales":80},"midnight-mountain-marathon","Midnight Mountain Marathon","2027-06-12",[77,78],"26.2 mi","13.1 mi",7,[],{"permalink":82,"name":83,"startDate":84,"city":85,"distances":86,"distanceKm":90,"ficheLocales":91},"beast-of-the-blacks-ultra-40-mi-plus-20-10-mile","Beast of the Blacks Ultra 40 mi plus 20 & 10 mile","2027-03-06","Crickhowell",[87,88,89],"17 km","32.5 km","65 km",8,[],{"permalink":93,"name":94,"startDate":57,"city":95,"distances":96,"distanceKm":99,"ficheLocales":100},"the-beacons-ultra-marathon-and-half","The Beacons Ultra, Marathon and Half","Brecon",[59,97,98],"42.195 km","80.5 km",14,[]]
