Garmin 405CX

Whoa. Just noticed that today’s Deal of the Day at Amazon is for the Garmin Forerunner 405CX GPS watch with heart rate strap for only $149. Some of you may be aware that Murdoc is a runner, and one of the biggest things he’s done to improve his training is to use a GPS.

I use the 305, myself, but a lot of guys I know use the 405. If you run (or bike) and have been thinking about getting a GPS, here’s a good chance to get one pretty cheap.

Also makes a great Christmas present for the runner in your life. Seriously. Highly recommended by Murdoc.

Hurry, because I don’t know how long the deal lasts.

UPDATE: Looks the one-day sale is over, but it went up to only $159. Murdoc still thinks that’s a good deal. See the comments section for some more info on using these when working out.

I’m not super fast by any means, but I cannot overstate how much of a benefit one of these has been to my training and racing. It’s also very useful on the bike.

    1. It is a HUGE training aid.

      First, you’ve got an accurate measure of how far you’ve gone and how fast you’re going. In real time. This is great because you are no longer limited to known routes and you get instant feedback about how you’re doing.

      Secondly, it has a lot of features which allow you to set up workouts with specific goals. Things like “run so far at such and such pace, then so far at so and so, etc. etc.”. And it can be set to let you know when you’re running too fast or too slow. Great for interval workouts and such.

      With the heart rate monitor, you can also base your workouts on heart rate, which is a pretty good measure of “effort,” which in turn is often a better standard to use than simple time/distance goals. (Though I don’t do this all that much.)

      Finally, it’s a great tool for during a race. Makes it much easier to stick with your plan, particularly early in long races when you’re likely to go out too fast.

      And it’s just plain cool to upload your workouts and analyze them on a map. Good stuff.

  1. Do you trust the customer reviews? The ratio of low (1 star) to high (5 star) reviews on the 405 is significantly higher than on the 305. I have never seen these items in person, so I can’t vouch for the accuracy of the reviews.

    1. I haven’t read through the reviews. I use the 305 and I have heard that a lot of people like it a bit more than the 405, mostly because the larger size of the 305 allows for a bigger antenna (better/quicker GPS) and slightly longer battery life. I think the very first 405s (not the CX model, if I understand correctly) had a few issues with the touch bezel thing but I’ve heard that it’s better on the newer ones.

      The 305 is much larger. I’d prefer a smaller one like the 405 but it’s not all that bad once you get used to it.

      The 305 still has a lot of fans, but I think it’s mostly because it’s so much cheaper. Not the case now.

    2. Another thing which the 405s have but the 305s don’t is the ability to just set a pace and go.

      For instance, you can set the 405 for, say, 8:00 miles. You press START and start running, and the Garmin will show you how far ahead or behind an 8:00 pace you are in feet. Such as, you’re 127 feet behind where you would be if you were running 8:00 miles. I can’t explain why, but this type of measure seems more motivating to me on hard workouts than just seeing that I’m running 8:05 instead of 8:00.

      To do this on the 305 you have to set up and save a workout with a distance and pace target. On the 405 you just set a pace target and go, which is quicker and doesn’t clog up your saved workout list.
