The Map-Equipped Treadmill That Can Recreate Any Hike On Earth

Dreaming of running up Mt. Kilimanjaro? Do it today. The NordicTrack X7i Incline Trainer raises and lowers itself to mimic the dips and hills of real-world topography.

The X7i downloads maps over Wi-Fi from a Web site called iFit, which lets you pick popular routes like San Francisco’s Golden Gate Trail, as well as treks you’ve designed on your computer across any territory covered by Google Maps. As you run, a seven-inch screen scrolls the map and shows snapshots of passing landmarks. (The “scenery” will help distract you from the burning in your legs—the machine cranks to 40 degrees upward or six downward.) Afterward, the console sends workout data to the Web, where you can analyze it and plot your next run anywhere on the planet—or beyond, since Google Moon is open for hikes, too.

H20 Holder

Stay hydrated without strapping a bulky water bottle to your hip. The Platypus reusable, flexible nylon and polyethylene pouch squishes to stow in a pocket and shrinks as you drink. When empty, it rolls up for easy storage, and a bacteria-fighting lining means it won’t get skunky.
