High Quality Content by WIKIPEDIA articles! Yiannis Tridimas (born Andros, Greece on 22 February 1945) is a renowned long-distance fell runner, noted as being the first and only 60 year old to have completed an extended version of the Bob Graham Round, covering 60 peaks in under 24 hours. He completed the course on his third attempt, during the weekend of 6/7 August 2005, after his first attempt was curtailed by injury and the second by extreme hot weather. Yiannis is among a group of a few who have completed all three major 24 hour rounds in England, Scotland and Wales (Bob Graham, Ramsay and Paddy Buckley round). In addition, he completed his own 24 hour round, the Meirionnydd round in Wales, which he rates as one of his hardest challenges yet. He completed the Cuillin round in the Isle of Skye, which he rates as one of the most scenic and most challenging; not ideal for those not fond of rock climbing, as it includes both the Black and the Red Cuillin. He has completed a solo run between Snowdon and Pumlumon in Wales, taking in all the major hills in between. Other ultra distance completions include the Joss Naylor challenge in Cumbria, the Leventon line in North Wales and the South Wales traverse.
