OH Andi and Jill- I am just 2 days behind you (tomorrow I will finish week 1)!!
It is going really well so far, much harder than the first time I did it 2 years ago for the obvi reasons.
**for those that dont know, I had a serious bicycle accident in Sept, Surgery to repair my nose and sinuses in Oct, and due to the risk of hemmorage, I could not elevate my heart rate until mid January. So basically I am just starting to build my endurance back now.
However, I did find that day #2 was much easier on me than day 1, so we shall see!
