At age 34 Canadian Brent McMahon attempted his first Ironman in Arizona. Previously, he was a 2004 and 2012 Olympian, and 2014 was going well with four Ironman 70.3 wins. On the starting line he didn't have a time goal, nor had he even pondered a finishing time before this race. He followed a race plan crafted with Lance Watson, his coach of 20 years. That included a caloric intake of roughly 500 calories per hour on the bike while ignoring his competitors. When a couple contenders passed him early in the bike he started to ride with them but backed off when he realized it required a greater power output than he planned to ride. He finished the bike in third after a 4:21 split. He ran the first half of the marathon in 1:20 and finished with a 2:43 run, giving him a 5 minute margin of victory and a 7:55 final time, the fastest Ironman debut in history. Despite competing at a level far above most triathletes, his race execution tips are golden and helpful to all triathletes. Links Brent's Twitter account @tribrentmcmahon
