  1. Great review on the Garmin Forerunner 235,

    I am in the market for a new watch for the upcoming running season here in the Midwest. I have been looking into Garmin quite a bit lately and this review is a great bit of advice. Do you suggest anything other than the forerunner. 

    Does the forerunner have any type of memory capabilities? As far as logging a race?

    Do yo suggest a superior watch above all that will handle the test of time?


    • Hi, Nicand thank you.

      Thank you for kind words.

      The memory of Garmin Forerunner 235 is excellent. It can store up to 200 hours of activity history which mean that it is beneficial to analyze the progress and keep track of the activities.

      It will always come new and great watches. But I think that Garmin Forerunner 235 has shown that this is one of the best running watches which have been made. So it will be beneficial for a long time. But Garmin is one of the best brands in the running watches, so they have a lot of great running watches. For example, the Garmin vivoactive HR which you can see more about here.

      If I can help you with anything else, or if you have any questions, don´t hesitate to contact me.

  2. Always I had avoided using any type of watch during physical exercises because of the sweat, but right now it is not a problem. The Garmin forerunner you review seems to be genial for my fitness activities, I have seen other options but yours is great with many possibilities, also to be just a watch. Thank you for this review 🙂

    • Hi, Maria and thank you.

      Great to hear about your benefit of this article.

      About the sweat using the running watches in fitness activities, I want to recommend not to have the watch strapped to fast on the wrist. It is strong, so it’s usually not necessary either. Also, the urine is better than a few years ago, so you do not sweat like a few years ago. But it is on same time right to have in mind that people are different about issues like this so many others.

      If I can help you with anything else, or if you have any questions, don´t hesitate to contact me.
