Garmin Forerunner 610

Garmin's first touchscreen GPS sport watch, the Forerunner 610 has lots of useful features. One that's great for explorers is the back to start feature which guides you back to where your run began. You'll also love its touchscreen that lets you easily scan through functions on the fly. Plus, it tracks how far you've gone and lets you race against a prerecorded course to gauge your training progress. And when you're done with your workout, you can upload your data to Garmin Connect, their online training community, so you can track your training and share your results. It even boasts a customizable display and a rechargeable Lithium-ion battery that runs for up to 8 hours per charge.
