Garmin Forerunner 235 vs. 245: Is the Update Worth it?

garmin forerunner 245

The Garmin Forerunner 235 is basically the holy grail of entry-level GPS watches—you’ll find it on the wrists of runners who specialize in all kinds of distances, from 5k to marathon. In April 2019, Garmin released the updated version of the classic watch, called the Forerunner 245. The Forerunner 245 comes with a sleeker design, a music option, and greater tracking features—but is it worth the extra $50-$100+?

If you’re wondering whether to upgrade from the Forerunner 235, or are just deciding between the two watches, here’s what you should consider.

Note: I don’t own either watch, but I tested both at one point. I actually ordered the Forerunner 235 in December 2018, thinking it would be my first GPS watch, but I wasn’t totally satisfied and opted for the Vivoactive 3 instead. I had the chance to test the Forerunner 245 for a month in November 2019 for a GPS watch comparison between it and the Vivoactive 4.

Also, as a quick background, I’m a distance runner (mostly half and full marathons) but have also dabbled in triathlons and actually cross-train most of the week.

Garmin Forerunner 235 vs. 245: Should You Upgrade?

Things in Common

The primary function of both the Forerunner 235 and 245 is to track running (what a surprise haha). You’ll also get fitness stats like heart rate, step count, VO2 max, and sleep. One of the major drawbacks of both watches is that there’s no barometric altimeter, so you won’t be able to see the flights of stairs you’ve climbed daily, and your elevation gain stats will be based on GPS, and are therefore less accurate.

With both watches, you’ll also get smartwatch features: you can see texts, calls, calendar reminders, and other notifications from your smartphone. There’s also LiveTrack, which allows your friends and family to follow your activity in real time.

Price Point

This post contains affiliate links, meaning that I may earn a small commission on any purchases you make. It doesn’t cost you any extra, and it’s a great way to support my blog if you found this post helpful! Even just clicking through them helps 🙂

On the official Garmin website, the Forerunner 235 costs $250. The Forerunner 245 costs $300 (no music), or $350 for the music version.

On Amazon, the Forerunner 235 costs anywhere from $120-200 (this is the official Garmin listing on Amazon—other listings may be slightly cheaper or more expensive, so look around). The Forerunner 245 typically costs $250-300 (no music), or $300-350 for the music version.

The Forerunner 235 obviously wins on price, being around $50-100 cheaper than the Forerunner 245. You can even get the Forerunner 235 for under $200 on Amazon pretty consistently, and that’s a great deal for a solid GPS watch.

You may also want to check other retailers for pricing:


The Forerunner 245 is much sleeker in appearance, and way more comfortable to wear. Unlike the heart rate monitor on the Forerunner 235, that on the Forerunner doesn’t jut out and stick into your wrist. The Forerunner 245 is also 3.5g lighter, and doesn’t feel as “cheap” and plastic-y (it’s still primarily made of plastic, but it’s a nicer-looking matte plastic, rather than the shiny kind).

If you’re planning to wear your watch only for running, than appearance and comfort don’t matter as much. But if you want to use your Garmin as a daily fitness and sleep tracker too, I’d recommend the Forerunner 245.

Battery Life

On smartwatch mode, the Forerunner 235 lasts 9 days vs. the Forerunner 245’s 7 days.

On GPS mode, the Forerunner 235 only lasts 11 hours to the 24 hours for the Forerunner 245. With GPS and music, the Forerunner 245 lasts 6 hours.

The Forerunner 245 is definitely a stronger choice if you plan to be running for a long time, or if you don’t like to charge your watch often.

Extra Features of the Forerunner 245

Incident Detection—alerts your emergency contacts with your location if an incident is detected (you must be connected to your phone, though).

Stress—monitor your stress levels throughout the day

Body Battery—basically the amount of energy you have left

Music—you can download and play music from your watch using Spotify Premium and Deezer, as long as you’re connected to Bluetooth headphones or a speaker. (There is a non-music version of the Forerunner 245 though, so make sure you get the music one if this feature is important to you).

Training Status and Training Load—whether your training has been productive, and if your training is at a smart level

UltraTrac—a tracking mode that periodically shuts off GPS to conserve battery; especially helpful for longer races like ultramarathons, but it does compromise accuracy a bit

Swimming—the Forerunner 245 tracks swimming (distance, strokes, pace, swim efficiency); you also get underwater wrist-based heart rate. The swimming stats have always been slightly off for me (10-15% more distance than reality), so just know they aren’t super accurate, especially if you like to vary your stroke in the middle of a lap.

Cardio tracking and other activities—you can track Strength, Cardio and Elliptical Training, Stair Stepping, Indoor Rowing and Yoga; there’s also automatic rep counting for strength training

Pulse Ox—blood oxygen saturation—how your body absorbs oxygen, which can be helpful for sleep stats

Navigation—you can use point-to-point navigation on your watch, and see a live bread crumb trail of your route

The Bottom Line

The Forerunner 235 still remains a great entry-level GPS watch for under $200 on Amazon. If you:

  • Will primarily use the watch for running, and don’t care to track swimming or other cardio
  • Don’t plan to wear it all the time as a fitness tracker or smartwatch
  • Aren’t looking for a watch with a music feature
  • Don’t need super long battery life for longer events like ultramarathons
  • Won’t use the extra fitness data like Training Status/Load

I’d recommend the Forerunner 235 over the Forerunner 245 to save you some money.

If you do want any of those features, and they’re worth the extra $50-100+ to you, then go for the Forerunner 245.

I personally didn’t love the Forerunner 235 myself, as I wanted a more comfortable watch to wear all the time, swim tracking, and more accurate elevation stats (and stair tracking). That’s why I went with the Vivoactive 3 in the end. I did quite like the Forerunner 245 though, and would’ve considered upgrading to it at some point, if it weren’t for the lack of barometric altimeter.

  1. I’m so interested in the Forerunner 235 or 245, but neither have barometric altimeters, which I find so weird. If they had that feature they’d both be the perfect entry level running watch for basically any runner.

    I only run and am looking for a barometric watch that provides many options for training, such as data options and recovery. Do you recommend anything? Sorry, that is a very open ended question, but any guidance you could provide would be great.

    Btw, love your blog! I find the reviews very helpful. Thanks.

    1. Hi Peter! It’s no problem, happy to recommend something, and thanks for your comment 🙂

      I also find it weird that the Forerunner 235 and 245 don’t have altimeters, especially the 245. You might consider the 645 instead, which has the training stats and an altimeter. It’s often $200-$300 on Amazon, so it’s in a similar price range. Here’s a review of the 645 vs. 245:

      Otherwise, if you’re willing to go with a different brand, I recommend the COROS APEX. It also has training stats and an altimeter, and the battery life is insanely good! Here’s a review of the APEX vs. Forerunner 245: I plan to upgrade to the APEX after my Vivoactive 3 Music dies (which is also a fine option if you want a more budget watch – it has an altimeter, but doesn’t have more advanced training stats).

      Let me know if you have more questions!

  2. I have a 235 and I really like it and wear it all day long, I have found out that the heart rate its not as accurate as I need it. Does the 245 has a better heart rate sensor to make worth the upgrade or they are comparable? I’m a beginner runner by now doing 5 runs a week.

    Thanks for any insight.


    1. Hi Laura! The 245 does have the latest HR sensor, so it should be more accurate than the 235. The general consensus seems to be that it is generally food, but that it struggles with accurate tracking when recovering (like during intervals). Unfortunately, optical HR sensors will never be 100% accurate, so I’d recommend a chest strap if you want truly accurate HR data. That would be cheaper than buying a new watch too 🙂 Hope this helps!

  3. Hi! I have a 235 now, and I’m wondering how the vibration and sound tones on the 235 compare to the 245. The 235’s tones sound very mechanical and the vibration isn’t especially smooth. Sometimes when I’m running, I don’t even notice the mile lap alert tone. What are these features like on the 245? Are they improved?

    1. Hi Katherine! I don’t own either watch, and I tested them several months apart, so I don’t have a good answer for you. I don’t remember having a problem with either the vibration/tones of the 235 or 245. I tried asking in a Garmin FB group for you, but got no response since this morning. One thing that may be helpful to know, however, is that if you have the music version of the 245, you can get audio prompts through bluetooth headphones. I wish I could help more, I’m sorry!

    1. Hi Adrian! No, unfortunately it is not possible. If you want to download golf courses, you’ll want a gold-specific Garmin (the Approach series) and not the Forerunner series.
