Welcome Renee, you'll be in shape as you stick to the discipline of it.
Well I just completed W1D2, and the first half was great! The second half, uh, well, I sorta hit a wall. It felt like the wind was knocked out of me. But I kept going and was glad to finish.
It was kind of funny because when the lady's voice came on and said, "You have just two runs remaining and then you're finished", I wanted to say, "you aren't kidding!" Maybe they should change her text to say, "You have just two runs remaining and then will have completed your running for the day" :).
Keep it up everybody, let's do all 9 weeks!
