Combat your post-Thanksgiving carb overload and turkey tiredness with a trek from the marathon-walking, stair-climbing people behind Big Parade LA. Meet at the Chinatown Metro Gold stop for a 15-mile loop over stairways, bridges, streets and over seven miles of urban dirt trail. And don't worry, there's a transit-friendly bailout halfway through for any "I've made a huge mistake" moments.
