EP- Fred Whitton need entering on the day the entries are released (around about new years day if I remember correctly) and even then with snail mail you never know... Dales Etap is similarly tough and a bit later in the year entries on line but get up in the early hours to enter or you won't get in. A bit less popular but still a great race is the Grand Fondo Cymru which starts and finishes in Bala, there is a choice of distances and you can opt to cut it short or go longer at a point in the course which might be a comfort.
