This week Michael, Alex, and Katelyn dig into the mailbag for some of the toughest questions runners face: how much you can realistically improve in six months before a goal marathon, whether it's insane to run two World Marathon Majors a month apart, finding a super shoe that won't aggravate a bad knee, and more. Plus, Michael gets called out (fairly) for some inaccurate comments about the Glass City Marathon.Chapters:0:00 Intro6:34 Momentous Sponsor8:42 Back from the break9:20 Mailbag: super shoes for a bad knee33:12 Lagoon Sponsor34:51 Back from the break35:24 Voice note: running two World Marathon Majors in a month52:48 Join Marathon Handbook RunClub56:12 Back from the break56:26 Mailbag: chasing a sub-3 marathon1:22:52 Mailbag: a comfier race day shoe1:30:46 Correcting our Glass City Marathon comments1:37:16 Mailbag: adding volume to a sub-20 5K plan1:43:17 Wrap upSUPPORT OUR SPONSORS:This episode is presented by Momentous.
