The Podcast-series he co-hosts have been moved to behind a paywall (unlike the ones co-hosted w ex-LR Intern Alex), so I have no way of checking if he's still doing them because obv I'm not paying to hear Matt F talk
You are right about the IG though. Amusing and completely expected from Matt who loves to ruin relationships. Maybe Matt realised training for the Mile then only doing a 6 week Marathon build isn't going to work? Maybe Max didn't agree with Matt selling Sweat Elite to a new acquisition?
Either way Matt just said he was going to run 4:05 for the Mile, never looped in shape for it, ran 4:17 and then loosely blamed it on his Aunt dying in his strava caption.
