Wicked stoked that we got to talk to Lou Serafini this week. He's been making the podcasting rounds lately because he just recently broke 4:00 in the mile at BU. In addition to being an elite runner, he is also the Community Manager at Tracksmith, a Boston-based running brand that we're big fans of. We talked to Lou about his running, his working, his memories of Sir Roger Bannister and his takes on World Indoors, plus your listener questions!

You can find Lou at @louisserafini on Twitter, @louserafini1 on Instagram and on Strava. As always, we're at @1609pod everywhere. Thanks for listening!
