The fastest way to lose weight is to sweat it out in 100-plus-degree weather, while bouncing up and down on hot asphalt. Torture? Yes, but you can psych yourself out if you run fast and let yourself be distracted by the view on the scenic incline of the Dreamy Draw Recreation Area. The mile-and-a-half bike path winds through shaded areas dotted with boulders where you can stop to catch your breath. Heat stroke and dehydration aren't concerns: Drinking fountains appear at frequent intervals. Dreamy Draw, open from 5 a.m. 'til 10 every night, is your shortest and most visually pleasing route to cardiovascular success.
