Well , overweight and over 50 but still managed it.
In fact, just left my phone at home and run until I felt like walking, and pretty sure I ran at least 4 miles...actually enjoying it now.
So,for anyone who starts off running in the dark because you don't want anyone see you in lycra....guess what, nobody cares! The only thing that matters is that you are getting fitter.
So...to all the more rubenesque people out there...you are not alone.....you can do it. If I can, anyone can .
Good luck everyone, and....finally the world won't end if you get stuck on a week, just repeat it until you are ready to move on.
