I started this on 9th Nov and today, on my 53rd birthday, I have graduated. I am absurdly pleased and completely staggered at the progress I've made over this time. I've only just started posting here, looking for tips on moving forward, but it was all the posts and inspiration from here that got me to do it in the first place. So thank you all!
My first run, I didn't tell my husband I was going to start (in case I didn't get into it), but came back as red as a beetroot sweating ketchup, and had to fess up as I clearly looked a state! But I kept at it, and started to feel like a runner around week 7 and 8, and have really enjoyed week 9. I run very slowly, but that's ok. Going to consolidate now for the next few weeks - and with the brilliant suggestion of Zaza0309 - I'm going to graduate again and again, rotating through all the different coaches for variety! I still feel I need that voice encouraging me along, and will slowly work on my pace.
To anyone thinking about doing this - just get started - if I can do it, anyone can. I can't recommend it enough. It is a minor miracle what can be achieved.
