In this Field Notes episode, Siegfried “Sig” Tiegs shares how his first backyard ultra ended in an ambulance. Two miles into lap 6, his vision blurred and the nausea hit. A few hours later, he was in the ER with rhabdomyolysis, aka rhabdo. Sig breaks down the story, his numbers, what rhabdo is, how athletes end up with it, and the perfect storm he walked into without realizing it. He does hard things so you don’t have to.
