Using the follow-on podcasts from Laura I've finally managed to get to 5k a couple fo times this week. Feels good, especially when I reflect on my starting point back in July when I was questioning how I could keep going for 3 minutes!
I recommend the follow-on podcasts. I find it easier to run to the music and ensure the steps taken are in time. For each of these I get to about 4.2km in the 30 mins so I then do a slow jog for 5 mins to get to 5k in +/-35 mins which according to my age grading is about right! Hurrah! Like the C25K podcasts the one I've used now has enough bite to make it feel a challenge. I know I need this to keep me going.
