Jordan and Gerard Donnelly break down Half-Ironman training: beginners need 6-12+ months, experienced athletes can do it in 8-10 weeks. Build your bike rides past race duration (if your race is 3 hours, train up to 4), do at least two swims weekly in open water, and practice your race nutrition at full intensity before the event.

Questions this episode answers

1,900 meters

Two swims per week (three is a bonus)

Approximately 90 km, taking roughly 2–4 hours depending on athlete level (example target: 3 h; build rides to ~4 h)

Solid blocks or intervals such as 1×60–90 km, or intervals like 4×30 min / 3×40 min / 2×60 min at ~75–90% FTP

Prioritise endurance and strength (long runs longer than race time), add elevation, practice race-pace runs off the bike (e.g., 5–13 km at race pace), and include hill repeats and S&C.
