Coming October 16, 2015. A weekend of fall foliage, running, and more with the Runner’s World Half Marathon and Festival. Held in Bethlehem, Pennsylvania, you’ll have 3 courses to choose from: 5K, 10K, and half marathon. Or be ambitious and choose the Hat Trick (all 3 distances!) or the Five and Dime (both 5K and 10K on the same day). This is peak fall foliage season, so it should be a colorful race with some hills and cool weather. There will be loads of informative seminars related to running, pre-race warmups, a dog run and a trail run, as well as a health and fitness expo.
