Mark McCabe wrote triathlon into his social calendar in 2020, stayed stuck at a 5:45 for four years, and then decided to find out what would happen if he actually gave the sport what it was asking for. Two and a half years of consistent work later — including a build block that got replaced by 23,000-step days in Italy, a Zoltar fortune machine in a casino, and instructions from his coach that scared his wife — he finished Ohio 70.3 in 4:11:50, jumped from the 62nd percentile to the top 8% of his age group, and posted a 21-minute PR. This is the conversation about what actually caused that. Chris and Mark go through the volume data, the carb-loading protocol, the race-week preparation, the emotional regulation that kept the run from unraveling, and the mindset shift that made doubles feel like a gift instead of a punishment. Along the way, Chris shares his own breakthrough race — Ironman Canada 2011 in 97-degree heat — and the decade of volume that preceded it. If you have been stuck at the same result for longer than you would like, this is the episode to listen to.
