Illinois-based marathon runner Joe "McRunner" D'Amico completed this past Sunday's 26.2-mile Los Angeles Marathon in 29th place after eating only at McDonald's for 30 days. Over at his blog mcrunner.com he outlined his rules—he was allowed to eat non-McDonald's water, PowerGel, multivitamins, and ibuprofen— and kept a training log and food diary. Unlike pitcher Tim Lincecum's 3100-calorie In-N-Out meal, D'Amico far from stuffed himself for someone running ten miles or more on most days. About his regular diet he says,

My diet is probably closer to the average American than the average marathoner. While I try to watch my portion size, my selections tend to be based more on convenience and taste, rather than nutritional value.

For the purposes of this blog, I'll point out that he didn't eat burgers every day—about two out of three days he ate at least one hamburger (the smallest burger option on McDonald's menu) specifically without pickles. He also ate lots of grilled chicken sandwiches/wraps and hotcakes.

While training for the marathon, D'Amico raised over $28,000 for Ronald McDonald House Charities. He's still taking donations at firstgiving.com.
