The 2013 Kona runner-up uses this cycling workout in his Ironman buildup.
Long-course pro Luke McKenzie completes this bike set two or three times during his preparation for an Ironman. “It is important to do it rested and to give yourself time to recover after, as it usually takes a lot out of you,” he says. The focus of the workout is on improving Ironman-specific power and cadence, and the first time you do this session is usually the hardest. “But the second and third time you will see great improvement,” he says, “and I can guarantee you will enter your next Ironman with confidence in your bike fitness.”

After finishing ninth at the 2011 Ironman Hawaii, the long-course veteran became one to watch at the biggest race of the year. McKenzie followed that up with a disappointing 24th-place finish the following year, before he broke through at the 2013 Ironman World Championship. The six-time Ironman champion was second off the bike in Kona, posting a second-best bike split of 4:22:25. He held the lead from early in the marathon until 17 miles, when eventual winner Frederik Van Lierde passed him. His 2:57 run split led him to a runner-up finish on triathlon’s grandest stage.
