Garmins can cost a pretty penny. But good news for runners looking for a deal: the excellent Forerunner 255 is down to $250 ($100 off) for Cyber Monday.

SAVE $100: As of Dec. 2, the Garmin Forerunner 955 is on sale at Amazon for $399.99, that's a 20% discount on the list price.

However, as a cyclist, I am used to endless data after my exercise. My bike computer tells me my power, my left/right leg split, my cadence, my heart rate, live segment times, current and average speeds. It even predicts my Vo2 Max. If I wanted to I could have my core body temperature measured, my sweat, or even my coefficient of drag.

The ultra-affordable Garmin Forerunner 55 dropped to a rare and tempting price just in time for Cyber Monday. Get yours on Amazon and save.

The Forerunner 55 is Garmin's entry-level running watch and even at full price a more affordable option. But, to add to its appeal this is the lowest price I've seen it at. The Forerunner 55 is a reliable run tracker that suggests workouts each day to help you get fitter, and you can get any color at this price in Amazon's sale.

We've seen plenty of great smartwatch deals over the past few days, but if you're looking for a Garmin smartwatch that has a beautiful display, offers more than a week of battery life, and isn't going to cost over $200 — then the Vivoactive 5 is going to be the way to go.
