I am new to this site, and have never posted on any site before!! My husband and I have just completed week 5 of C2 5k. We never thought we would be able to run for 20 mins, certainly not when week one was running for one minute and it was so difficult. We are well into our 60s and a little voice is telling me to be careful...... I so wish we had done this 20 years ago. What a great programme, it has got us running, although very slowly and we are looking forward to completing it if we can.
