In this episode, Matt speaks with Mihailo Vukojičić about his journey from being over 100kg with unhealthy habits to becoming a 2:26 marathoner. Mihailo shares how he started running in 2022, ran his first half marathon in around 1:41-1:42 at 93kg, and later missed the Athens Marathon because his passport was stuck at the US Embassy.
They discuss his simple weight loss approach, technique changes from heel striking to forefoot running, using a 130 BPM heart rate cap to build aerobic fitness, and his 2:47 first marathon in Berlin 2023. Mihailo also explains how his fueling evolved from minimal race intake to 110-120g of carbs per hour in Copenhagen, and how he handled an injury-disrupted buildup with variable weekly mileage while relying heavily on confidence, perceived effort, and belief over device metrics.
The conversation also covers nutrition structure, the HEXIS app, legal supplements, lactate testing, HRV, training flexibility, doping debates, the Enhanced Games, WADA, and Mihailo's long-term goal of potentially reaching 2:13 and chasing a national record.
