About 500 people gathered recently outside one of the only green spaces downtown: the 1300 block of Brickell Avenue. They were the Brickell Run Club, all decked out in running shoes and workout shorts, ready to go for a run.
Once every week they run through the city. Some trips start on the corner of Southwest 13th Street and Brickell Avenue, then stretch past the Rickenbacker Causeway and back. But distance isn't the runners' only challenge. Frankie Ruiz, the club's founder, says it's hard for runners, bikers and pedestrians get through the city on foot.
At the height of the construction boom in 2006, Miami sprouted the second-fastest growing skyline in the world, behind Dubai. You could count over 70 cranes crowding each other out, like a tower of steel giraffes voraciously feeding on concrete.
