I also liked the addition of Garmin Coach, a new on-device workout program that lets you enter your current workout schedule and pace per mile to pick a running plan that will increase your endurance and speed. The Forerunner 245 Music took just seconds to lock onto a GPS signal when my colleague Mike Prospero launched a run, but the Forerunner 45, which we tested in both LA and Washington, DC, took between 15 and 30 seconds every time we started a workout. The Forerunner 45 is a solid fitness companion, but it's not as fully featured (or as fast) as its more expensive siblings, the 245 and the 945. You'll have to toggle up and down using the buttons on the left of the case, and a button on the top left turns on the watch's backlight for easier viewing in the early morning or evening. A stop-start button on the top right of the case launches a workout and also stops it. The five buttons are clearly labeled so you don't have to fumble around trying to find the right one with sweaty fingers on the go. Like the rest of the watches in the Forerunner lineup, the 45 uses button-based navigation, three on the left and two on the right, instead of a touch screen, to make it easier to use while running.
