There are a couple of campsites in Beddgelert, one in the forest, one on the road out towards NantGwyanant. Quite a few nice campsites in Porthmadog too. Youth hostels at NantGwynant, Pen-Y-Pass, Snowdon Ranger, Llanberis. A few bunkhouses too - Snowdon House, Bens Bunhouse, Pete's Eats has rooms. There must be loads of other options.
It was a cracking event JB. It was great to be part of such a small, cosy event and the enthusiasm of Henry and all the volunteers really shone through - I've never felt so pampered at checkpoints! Nice route too - saw some parts of Snowdonia I've never seen before. A great day out that will live long in the memory.
I've never done this distance before, the most being 37 miles at the Old County Tops but I had an OK run. Started too fast and stayed with the lead group of four up to Beddgelert before dropping back. Eventually finished 6th in 12:08.
