Jakob Ingebrigtsen is one of the most dominant runners on the planet: two Olympic golds, multiple world championship medals, and five world records by age 25. He's also coming back from February Achilles surgery and rebuilding toward a season that could include three more world record attempts.

Jessy Carveth sits down with Jakob for a candid, gear-nerd-friendly conversation about how he's actually training right now, what he really thinks of the "Norwegian Method" label, and how he uses lactate testing and elliptical work to keep VO2 high when he can't run. Jakob also breaks down one of the biggest shoe rotations in the sport, his hands-on role developing the Nike Victory spike that helped him break world records, and the new Coros watch he co-designed as part of the Fearless campaign.

And yes, we get into the Josh Kerr question. How real is the rivalry? Are they friends? Would they ever line up at a marathon together? Jakob answers all of it, plus opens up about why he sees himself debuting at 26.2 in his late 30s and what fearless actually means to him.
