2013 race (Saturday October 26th)
Race starts from just outside Llanberis. The route follows the A4086 and climbs to the top of the Llanberis Pass (Pen y Pass 1,100ft).
Dropping down to the Pen Y Gwyryd junction, the race then follows the old road along to the campsite until it joins the A498. The first 2K are track, downhill, then the surface returns to tarmac. There is a short, sharp uphill back up to the main road at the campsite. The route then continues to Beddgelert (200ft) and then continues along the A4085 to Waunfawr. From here it is a rapid climb to about 1,200ft at Bwlch y Groes (a short length is unmetalled) and then downhill to the finish in Llanberis.
