Ep 139: Izzi Batt-Doyle - The Australian Marathon Record Holder

Good Good Running · Nov 5, 2026 · 1h 1m

Izzi told someone close she’d run 2:20:40 - then went out and ran 2:20:38 in Chicago to become the fastest Australian woman ever over the marathon.

Izzi Batt-Doyle is back on the pod for the first time since Ep 36 to unpack the record: running the whole race side by side with fiancé and coach Riley, negative-splitting in the heat, why she ran fewer kilometres this build, and how her fuelling went from 66 to 119 grams of carbs an hour.

We also get into the Gold Coast half, why the best coaches hold you back, LA 2028 and Brisbane 2032, and her honest take on doping in the sport.

Thanks for…
