Kennesaw resident Lance Lewin bikes in Brandon, Fla. Lewin took up jogging but became interested in mountain biking in 1996 after it was introduced as an Olympic sport in Atlanta. He started riding in 1997. Mountain biking requires the biker to sustain different topography like rocks, roots and rivers with a heavier bike than road bikes. The sport challenges the mind and body. <br> Photos courtesy of Lance Lewin
