Last year, over 4,000 Nashvillians took the Mayor’s “Walk 100 Miles” challenge and together walked 108,425 miles. Now with the challenge in its second year, Mayor Karl Dean will be holding regular community-based walks, but it’s up to you to walk all 100 miles and track them on this site. Everyone who completes the 100-mile challenge by the end of 2012 will receive a free Walk 100 Miles t-shirt and all the bragging rights that go with committing to a healthy, active lifestyle.
