Joggers (or as they like to call themselves these days, “runners”) often get into trouble when away from home. Stray too far from your hotel and you could wind up more lost than the plot of Lost. The Leikr ($279) is a GPS-powered smartwatch with a 2-inch, 320 x 240 color screen protected by Gorilla Glass. It features built-in GPS, Wi-Fi, and Bluetooth, and it can store 8GB of OpenStreetMap information. The Leikr also shows you vital stats like time, distance, speed, pace, and calories burned.
