RunThrough Trails
RunThrough Trails put on trail races across the UK and the Alps, built to the same shape wherever they are: a base camp, an ultra, a middle distance and something short, all starting and finishing in the same field. The UK calendar runs from the Lake District and Snowdonia through the Peak District, the South Downs and the Surrey Hills to the Dorset coast at Lulworth. Aid stations are stocked, the ultras carry GPS trackers, and the mandatory kit list is spot-checked at bib collection rather than taken on trust. Entry is through Let's Do This.
