## Resource

We had just the right amount of Dunkin’ coffee (a barrel) before this great episode! The main topic was everything we learned at the Boston Marathon, highlighted by Jess McClain running 2:20:49 to break the American Course Record by over a minute. We break down our experience the most magical weekend! The most memorable moment for us: Around 30k, Jess fumbled a bottle (with a gel on it) right at the moment when the big moves were happening. What do you do at that moment? Jess turned around, grabbed it, and somehow bridged back to the leaders by surging under 5 min/mile pace. It was an unthinkable moment of perseverance and smarts that will go down in US running history. NO CARB LEFT BEHIND. And there were other amazing topics when we stopped being obsessed with Boston for a few seconds! Other topics: carbs in marathons, insights from marathon training, a study on cycling training that examines what overlaps with the best performances, a parallel running study, and lots more. Boston, we love you and your unexplained steam coming from the ground! History fact: Paul Revere listened to the SWAP Boston episode.
