I’m doing my first marathon next spring, I’m just not sure if the AW is up to the job. I have it in my head that a Fitbit is good for up to 5k training, AW good up to half marathon but for marathons, ultras etc Garmin is the way to go. Even the most basic Forerunner 45 will do better than an AW for the serious runner. What’s your thoughts? Yeah the new Ultra might change things but I’m using a SE and sure as hell wouldn’t pay £800+ for a Watch, the wife would put me out if I did.
