This week on the Marathon Handbook Podcast, Katelyn Tocci and Alex Cyr pull back the curtain on their personal 5K training journeys — and the result is one of the most detailed, practical running conversations we've had on this show. An ultra runner who resisted speed training for a decade. A half marathon specialist chasing a collegiate dream time. Both took on a 12-week 5K build at the same time, and both have a lot to say about what happened.

How do you go from job-hunting after college to a 2:05:54 marathon, run in Toledo, in one year? Vinny Mauri did it, and now he’s one of the most talked-about American runners at the 2026 Chicago Marathon. Alex Cyr caught up with Vinny at the Chicago Marathon athlete availability, two days before his first big-city marathon. Vinny explains the 45-mile day that capped his build: 2 x 50 minutes in the morning and 4 x 20 minutes in the afternoon, both on the treadmill. He also explains how he picks his workouts by asking friends and Instagram followers to “pick a number one to four.”

Nike has announced three new race day shoes, and the headliner is the Nike Apex: a zero drop super shoe with 40mm of stack in both the heel and the forefoot, built to challenge the Adidas Adios Pro Evo 3 at the front of the world's fastest marathons. Alex Cyr and Michael Doyle break down the Apex, the Alphafly 4 and the $145 Swooshfly. We sat in on Nike's briefing with the executives and designers behind these shoes and draw on conversations from this summer with Nike athletes and with Brett Schoolmeester, the VP who has helped lead Nike's super shoe program from the start. We cover the Apex's specs and $350 price, whether Nike's athletes will embrace a zero drop racer, how hard it may be to buy a pair, why the Swooshfly is aimed at beginners and at China's booming marathon scene, and whether Nike now has the best running shoe lineup in the sport.
