In Our Questions for the Queen segment, Rebecca Rusch gets gross, talking about how to keep going when you have GI issues.

In our segment on The Course, we talk about road tactics on Hagerman, as what is often acknowledged as the best part of the race: Sugarloaf  Jonathan Lee’s training advice will — finally — cut you a little slack.
