If you're looking to take your cardiovascular endurance to the next level, don't miss this huge early Black Friday deal — the Garmin Forerunner 245 is currently 43% cheaper at Amazon, saving you a whooping $150.

This is one of the best Garmin watches we've tested, and a firm favourite with one of our team who has worn it for multiple marathons. The next generation also scored a solid 4/5 stars in our Garmin Forerunner 255 review. When we tested the 255, we loved the lightweight design, the high end software and the practical MIP display, which give it excellent outdoors clarity. It's less bulky than the Garmin Instinct 2 and cheaper than the Forerunner 955, making it a good fitness tracker for someone looking for a 'serious' tracker, without paying the higher prices premium Garmin products tend to demand.

If you're not sure a Garmin is the right smart watch for you, you can find lots more options in our round-up of the best fitness trackers, catering for a range of budgets.

The Garmin Forerunner 245 is one of our favourite running watches, and at 43% off in the early Black Friday sale, this deal is worth taking advantage of. While we're expecting to see lots of fantastic deals on Garmins, Fitbits and Apple Watches over the next few weeks, stock isn't guaranteed to last. That's why it's worth snapping up this huge $150 saving if you've had your eye on the Forerunner 245 for some time.

Features include a gorilla glass watch face, free adaptive training plans from Garmin coach, or you can create your own custom workouts. Safety and tracking features include incident detection (during select activities), which sends your real-time location to emergency contacts through smartphone.

You can also sync the watch with music streaming services, such as Spotify, to easily store and play your favorite songs right from your watch. No need to take your phone with you on your run.

Features such as the body battery and running dynamics tracking evaluates your current training status to indicate if you’re undertraining or overdoing it. Garmin also offers additional performance monitoring features, so if you're a junkie for stats and analysis, you can get into the nitty gritty information that the watch stores after each workout. Track everything from your recovery time to your stress levels and sleep.
