I'd told myself I'd get a Garmin once I made it to Week 4 but when I saw a good deal online, I couldn't resist and clicked the button. It was supposed to only arrive in time for my W4R1 but it arrived earlier, which was a nice surprise.
My intention / excuse for buying it was to be able to track my progress over time. I also had found that the tiny screen on my fitness band was near impossible to look at while running. In this regard, it's been a huge improvement!
Happy running everyone, keep warm!
