A podcast episode (How To Actually Improve In Triathlon) featuring Gerard Donnelly and a co-host analyzing the year-long turnaround of an athlete named Justin. Key themes: consistent, focused practice; measurement and re-testing; execution (holding narrow power zones on the bike) produced big race gains; and athlete self-review/engagement with data. Notable outcomes reported: swim 1km PB within an endurance session (from ~1:46/100m to ~1:36/100m), 20-minute power test improved from ~250 W to 273 W, bike race of 40 km at 39.8 km/h, and running improvements to a 5k at ~3:37/km and 10k off the bike at ~3:55/km. The hosts emphasize trust in long-term consistency, focused practice, measuring execution (time in target power zones), and athlete investment in their data.
