If you feel nervous about your upcoming race - you’re not alone. Most runners suffer from MarathonPhobia.

Talking to my running crew during our 12-mile taper run in preparation for the Chicago marathon – everyone shared their marathon anxieties, including (in no particular order):

1. Fear of letting down other people (family, friends, charity sponsors…)

2. What if I have a gastrointestinal issue?

3. Did I do enough training? I didn’t do enough hill workouts– it’s too late now

4. Will there be big lines for the Porta-Potties?
