I'm currently on Wk5 and planning to do run 2 tomorrow night after yesterday run 1 of week five I've developed muscle ache across the backs of my shoulders about half way down my shoulder blade. I'm guessing its from swinging my arms whilst jogging I have been doing leg stretches religiously after each run but nothing for my upper body.
Has anyone else experienced this? Can anyone recommend any stretches that might help?
Thanks in advance Allie
