- Up to 13 hours of battery life in GPS mode
- 7 days in smartwatch mode
At this price, you’re ideally looking for a running watch that will last you a week of training on a single charge and one that has enough single-session juice to cover a long marathon. The Garmin Forerunner 45 does both easily.
In our tests the watch managed a full week with hour-long runs daily and then a 2-hour long run on the Sunday. We did, however, switch off the smart notifications out of preference and this may have extended the life a little. But there’s ample battery here.
Running watch tech has taken some giant leaps forward in the past few years and this richly-featured Forerunner shows that entry level runners can now expect some of the brilliant tracking smarts we once only saw in the flagship models.
The Garmin Forerunner 45 is a clever, compact and cost-effective device that has more than enough for beginner runners.
All in all, it's a solid option that’s punching well above its price tag.
Who’s this for?
The Garmin Forerunner 45 is a running watch for beginner runners who want to track their miles, and keep an eye on their everyday activity and health, but don’t want to spend their monthly pay packet on doing so.
But it will also suit those who prefer to keep their run-tracking simple and don’t need the extra frills and features that come on some do-it-all higher end devices.
If you run for fitness, are a weekly 5km-er or you’re training for a first half marathon and are not sure if that will be all you ever want to do, then this is your watch.
Should you buy it?
This is one of the best value running watches out there right now. You’ll be hard-pressed to find a more comprehensive device for this price. So, yes, if you’re the runner we described above, we think you’ll enjoy it.
