It also provides an estimate of VO2 max—the amount of oxygen your body can use during intense exercise—and a number called “Body Battery” that estimates your energy reserves based on your heart rate, stress and activity that day. A higher number means you have more fuel left in the tank, while a lower number means you’re running on fumes.
Along with a guess at the calories you burn and sleep monitoring, the Forerunner 45 has plenty of stats to keep you busy. Our tester says the numbers (and intuitive interface with Garmin’s compatible app, Garmin Connect) are fun to dive into, but ultimately it’s the watch’s basic functions that make the 45 a great value.
“I’m not an ultramarathoner or triathlete, so I don’t really need anything more than the 45 has,” he says. “It has enough data to keep me busy if I want to read into it, but it also just shows me how far and how fast I run, which is enough for me.”
To check all the data, the watch pairs easily with a cell phone for automatic syncing via Bluetooth. You can watch real-time stats, like heart rate and steps, in the Garmin Connect app while you’re wearing the watch.
Once it’s paired with your phone, you can choose to get notifications on your wrist. Texts and calls show up on the watch face, and you can answer a call by pushing a button on the watch (although you can’t talk through the watch—you still need your phone for that). But never fear, you can also turn notifications off if you don’t want your watch blowing up during group texts.
The Garmin Forerunner 35 was a sleek and capable running watch for years. But the Forerunner 45 is even better.
Garmin updated the entry-level 45 with a refreshed round face and a new bag of tricks that includes customizable watch faces and personalized training plans from Garmin Coach. The improvements make the 45 an ideal GPS running watch for new runners, runners on a budget or experienced runners who only want to track their distance, pace and time.
