About Dave


Dave, based in Chiswick, West London, has been immersed in triathlon and endurance sport for the last thirty years, competing in a range of events from grassroots 5k’s to world championship Ironman events and Ultras including the iconic Marathon des sables desert race.


His Journey into sport started at a very young age, but it wasn’t through clubs and formal events, but racing his BMX around building sites. jumping off things he shouldn’t have been jumping off, trying to deliver newspapers as fast as he could on his racer, or trying to beat his PE teacher on the weekly cross country run, and failing miserably.


Way back in 1988 there was no internet, no mobile phones, and no clever GPS watches. Jogging was becoming a cool thing, and with a pair of HiTec silver shadow trainers, Dave began to enter the world of endurance sport. In 1998 he ran his first marathon in London, which proved to be a challenging day off the back of one 16mile ‘training’ run, but nevertheless that emotional finish line feeling sowed the seed for many forthcoming years of fun racing. After dabbling in a few local triathlons, Dave entered his first UK Ironman in 2006. He built his TT bike from eBay bits, bought a used wetsuit that had the arms chopped off and hobbled his way around to the finish line in a time of 11:38. The Triathlon bug truly took a grip and his journey of becoming a coached athlete began.


Over the last 5 years Dave has been coached by one of the UK’s leading Triathlon and multi-sport performance coaches within TTT. During this time he has been exposed to evidence based coaching principles that have allowed him to become one of the UK’s elite age groupers and a well known character in the triathlon community


Dave lives in Chiswick, West London, with his wife and two daughters. His professional career as a dentist and dental practice owner spans many years and he understands first hand, how busy lives can leave aspiring triathletes with limited amounts of training time. With highly effective and bespoke coaching, Dave has learned what it takes to be a time efficient and successful endurance athlete. Dave firmly beleive’s that being coached should be a fun and enriching experience, that dovetails perfectly into busy lives.


Meet Dave


‘Triathlon and endurance sport has given me so much throughout the years. As my own journey continues, i’ve realised that whilst race results and day to day metric's are important, one overlooked aspect is the social connection that we make with others. The giggles, the friendly banter and the championing of each other is the real reason i have stuck around for so long. As a coach there is nothing more satisfying than guiding a beginner or a more experienced athlete along a journey that enriches their lives and expose's them to a tribe of like minded individuals. I will be every bit as ambitious about your own journey as I am my own. ‘
