Taking place in north Wales, this weekend of triathlon is not for the faint-hearted, incorporating the Snowdonia Triathlon, the second event in the Always Aim High Adventure Triathlon Series. Competitors start with a stunning swim in the lake at Plas y Brenin in the shadow of the beautiful mountains, before taking on the formidable peaks themselves in a 60km bike ride and an off-road run to the finish.
