I am in my 6th week of the C25K program and finished my first 5K this past weekend! Only had to stop twice to take a short walk to slow my breathing and am blessed that I had my husband by my side the entire time encouraging me. It took me 43 minutes but I FINISHED. I have problems controlling my breathing which I know is wearing me out quickly, but I know this will improve with time. 56 pounds down since my lifestyle change and this program is a wonderful addition! Thank you Zen Labs!!
