Cool Running: Gear and Gadgets for Runners

You don't need much to become a serious runner. There's no big investment in gear or apparel required. "Running is definitely a low-cost sport, which is why it is so attractive," said certified strength and conditioning specialist Scott Greenberg. "I think it can remain that way," he said. "However, some new tools can and will definitely have an impact on those looking to maximize performance." For runners carrying smartphones, the running app market is full of possibilities for tracking, mapping and measuring runs.
