Zwiftalizer 2.0 Tutorial And In-Depth Analysis Video Hello everyone. Today, I am excited to share with you my brand-new video tutorial and in-depth analysis of Zwiftalizer - the free online tool for reading Zwift game log files. This video has something for everyone, from complete Zwift newcomers to level 60 pros. First, I cover the basics. Then I go over all the metrics in each chart step by step. Also, for the first time ever, I’m showing summary reports that use community data that I’ve been gathering for over two years - over two hundred activities by ten thousand users.
