Anyone know of some long continuous hills with good height again which does involve long drives from Shrewsbury - training for Cader and Snowdon in Summer. I've been using Shropshire Hills (and the usual Shropshire Series Races) but the maximum height gain i can get is around 300m in one continous run (then i have to come down to make another climb).

Someone mentioned the Berwyns or the Cambians but i dont know the area
