Snowdonia Marathon



Join Snowdonia Marathon
The Brooks Snowdonia Marathon has been voted best British marathon twice. The demanding and spectacular route, encircling Snowdon, Wales’ and England’s highest peak, gives the event a unique place in the annual marathon calendar.
The inaugural Snowdonia Marathon was held in 1982, and was conceived as a dramatic alternative to the numerous city and town races becoming so popular. The demanding and spectacular route, encircling Snowdon, Wales’ ad England’s highest peak, has given the event a unique place in the annual marathon calendar ever since.
In a 2011 poll by Runners World Magazine, the Snowdonia Marathon was voted the best Marathon in the UK for the second time. This is somewhat ironic since it is also regarded as one of the most difficult! Our success has been credited to three things; the beautiful scenery, the runners that organize the race and the hospitality of the local people.
Course highlights
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 Cwyryd junction, the race then follows the old road along to the campsite until it joins the A498. This 2km section is farm track, downhill, then the surface returns to the tarmac. There is a short, sharp uphill back up to the main road at the campsite. The route then continues to the 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.
