Just ran for 45 min plus the 5 min warm up for a total of 50 min, which totaled 5.6k. That was run 3, week 9! Now I have officially graduated.
Thank you all for the support in this community. Now it's on to more training to prepare for my first race. Not sure when but will report back.
What an amazing program this C25k is. When I started I never believed I could do this given my previous back problems and now I did it. Way happy.
