Preparing for Boston Marathon

Why it matters:

With Boston just days away, this is the episode you didn't know you needed. The course is deceptive — the downhill first half destroys legs that aren't managed carefully, and by the time you hit the Newton Hills, it's too late to fix your mistakes.

Scott and Brian Rosetti of V.O2 go mile by mile so you know exactly what's coming, when to hold back, when to push, and how to fuel and hydrate for one of the most demanding point-to-point marathon courses in the world.
