Everyone knows about the calf at this point but the details in this interview are wild. He said he didn't even feel it tear - just thought his legs were dead. Described it as "running through sand" the last 100m. Didn't put it together until after when it was still killing him. Got the MRI and yeah, confirmed strain.
The kicker: he's never had a muscle injury before. Ever. So he's basically figuring this out as he goes. Sounds like USAs and indoor worlds are up in the air. I hope he can fix it. That WR shape could win Gold at worlds.
