I graduated C25k about 2 years ago - since then I have run in 3x 10K "races" and 2xHM's. I now run 5 days per week - 3 of them are by myself and I follow a Jack Daniels training plan on those days and push myself according to his plan's requirements - on the other two days Saturday and Sunday, I do "social" running at my local parkrun and local running club. This past Saturday I chose to accompany a lady runner who has some 'anxiety issues" - I think that my presence and support of her as we ran was good for her and she appreciated it (35 mins for the 5K) . On Sunday, I at age 70, and 3 others at ages 74, 69 and 83 ran 6.5Klms together - stopping and starting at times as we had to cross roads, wait for pedestrian lights and conquer hills - we chatted to one another about everything at an average overall pace of 8:30 mins per k - a slow run but still hard work which took us almost an hour to finish (followed by a convivial healthy breakfast at a local cafe with all the faster younger runners)
I am so happy that I got off the couch 3 years ago. My whole life has changed for the better.
