Oh my goodness! This morning was insane. I went for my assessment run this morning and almost died. I run over twice the distance than yesterday (so I thought), but it was only about 70% further. Micoach (the adidas app I am using) couldn't gets good read out because I had to keep take walking breaks instead of starting out at a jog and build up to a sprint over 10 minutes.
Friday's run should be much tamer and easier for me to do at my level.
