4x6' low threshold on the way to work. It was pretty easy, despite it being difficult to stay in zone on the crappy urban loop available to me for inbound workouts. Also it was windy and cold. But the flipside of the work I've been doing up till now being (mostly) pretty easy is that I've held a negative TSB for the last two months and my CTL is at an all-time high (around 80 right now) and still climbing. And I feel fine and threshold is starting from a reasonable place. I'm excited. I think this is all going to pay off when I start really building. I hope so, anyway.
