Jamie Summerlin is running across America. He started in Sunset Bay, Oregon, on March 26^th. He'll finish on July 4th in Annapolis, Maryland. If you’re doing the math, that’s 100 days from coast to coast, on foot. If you’re still doing the math, you’ll realize Jamie is running 30-40 miles every day—more than a marathon, which is 26.2 miles—for 100 straight days. 100. Straight. Days.
