2hr half marathon training: Yasso 800s; bitter cold

Sub 2 hour half marathon training continues in January 2024. Lots of treadmill runs because of the icy conditions. I was able to get outside at least once, but it was bitter cold. Instead of a long run, I did a Yasso 800 workout on the treadmill.
