Seonaid; I started in June after a gap of thirteen years, and on the first morning I seriously could not run across the road! Now, nearly three months later, having run three times each week since, I can run 1.5 miles and hit a personal best this morning of 14 minutes, just slightly more than a 9 minute mile. I've discovered there aren't any easy answers - some mornings it feels really easy, and other times (like today), I truly feel like I am going to collapse. Some things that have helped me are:-
singing a song in my head to keep my rhythm going....... counting my breathing; breath in for two strides, breath out for two....... not looking ahead (it can be too daunting), but concentrating on the small are of road in front of me.......... drinking less alcohol! And do keep in touch with everyone here - they are SO motivating, and I'm sure will have much better help for you than I do. Good luck! Just keep doing it!
