This week is our first in a monthly series that we'll be doing on tech and gear for endurance athletes. Our resident guru is Erik Hall, who was originally with us back on Episode 127. This week, Erik addresses two burning questions: what was going on with Michelle's watch during her pacing that half-marathon last week, and what shoes should George wear for his trail 50K in January? Tune in this week--and in future episodes--to hear Erik talk about ephemeris data, which shoe he calls "The Tank," and more!
