The Snowdonia Marathon (Welsh: Marathon Eryri) was established in 1982 with the idea of being a dramatic alternative to the numerous city and town races that were becoming so popular. The route makes a circumnavigation of the Snowdon massif, starting and finishing at Llanberis. It is held annually in October.

In a 2007 poll by Runner's World Magazine, the Snowdonia Marathon was voted the best marathon in the UK.

A television highlights show is produced and aired by S4C. The BBC reports the news and winners on BBC Radio Wales and BBC Radio Cymru.

Since 2012 there has also been an annual Snowdonia Half Marathon, held in April, and mostly run on roads between Llanrwst, Trefriw and Betws-y-coed.
