Did my first day of week1 last night with my 17 year old daughter and I am still alive!!! Managed about 56sec on 3 runs then just kept moving as briskly as I could. My lungs have never worked so hard and my face was like a tomato but I felt good at the end. Met some fellow C25K who were really encouraging as they were on week 5 and I am determined to do this!!!!
