Let’s rewind to March 2nd, 2003, when the Garmin Forerunner 101 made its grand debut. This clunky, brick-like device was the very first in the Forerunner Series, paving the way for future generations of smartwatches for fitness enthusiasts. Although the Forerunner 101 looks archaic by today’s standards, it was a trailblazer in its time, offering runners and triathletes an innovative way to track their performance.

The Forerunner 101, despite its bulky appearance, packed a decent punch for its time. It came equipped with built-in GPS, maps, various training features, and even a modest grayscale display. However, it was far from perfect. The FR 101 required two AAA batteries to function, and with a mere 14-15 hours of battery life, users found themselves constantly changing batteries or investing in rechargeable ones. Additionally, the watch lacked essential features we now take for granted, such as a heart rate monitor and water resistance.

Looking back, it’s hard not to chuckle at the Forerunner 101 and its primitive design. Yet, it’s essential to remember that this watch was a groundbreaking device in its time, setting the stage for the wealth of advanced features and sleek designs we enjoy in modern Garmin Forerunner watches. The 101 may have been a far cry from the sophisticated wearables we know today, but it was a necessary first step in the evolution of the Forerunner Series, and its legacy still resonates in the wearable tech world.

2. Early models: 201, 301, 205, 305 (2004-2006)
