3 years ago I couldn't run a single mile without wheezing, last week I did my first sprint tri in Naperville. But the real lesson came at mile 2 of the run when I hit that wall, I grabbed a free GU packet off the aid table and suddenly my legs came back. I had trained with gummy bears and gels from my sister's pantry, never once spent $30 on the fancy stuff. Did anyone else just fluke into their race day nutrition, or am I the only one who skipped the whole fueling plan?
