hi trinity, thanks for the welcome
I've read alot of stuff about breathing techniques, shallow breathing and lack of core stability. I'm wondering whether my problem will improve naturally, as you say, by being more relaxed/increased endurance, or whether I should attempt to follow some kind of breathing pattern, or do core excersises?
It's really frustrating because my legs dont feel tired by the distances I'm currently running but I'm forced to stop before I want to by the stitch pain.
