Martin Yelling - Martin enjoys running on the trails and roads around his Dorset home and struggling to keep up with 2x Olympic marathon runner and wife, Liz. His competitive running background includes representing England at road and cross country running, a AAA's medal over 1500m, a top ten finish in the National cross country, some sub 30min 10k performances and a half marathon of 66mins. After snapping an achilles tendon in 1998 he switched to multisport and won the elite National duathlon championships twice, represented GB at world and European championships, recorded a sub 4hr half ironman and a 9.14 ironman and cracked the big one, the ironman world championships in Kona, Hawaii.  Martin 'retired' in 2007 and but has since run under 3hrs for the marathon and still enjoys running most days whilst not chasing around the house looking after new daughter Ruby. Martin's sister is 2x European cross country champion Hayley Yelling.

Martin holds a BSc in Sports Science and a PhD in physical activity promotion.  He's worked in departments at Loughborough and Demontfort University and is a regular writer and coach for running and triathlon magazines and websites including Running Fitness, Triathlon Plus, London Marathon News and Run247.com.  He has worked with marathon runners at all levels from total novices who think they can't do it(but actually can), to experienced campaigners.  He runs his own endurance sports coaching and consultancy company helping individuals and teams achieve their running, triathlon and health & fitness goals. He likes smiling. He's not as clever as Tom. (www.yellingperformance.com)
