Hi, I have been running for just over a year and completed my first 5k race for life last year. I have signed up to run my first 10k in Lincoln this April. However my training seems to be getting me no where! I have just been out for a 4mile run but just like the last few runs I have done I feel the need to stop at 2miles! I know I need to get through the barrier but my breathing causes me to stop. I am astmatic and usually take my inhaler before I begin my run. Do I need to take it again during my run? I don't want to become dependant on it. I have completed my run withr tsling it again but my breathing sounds bad. Also I am getting a lot of pain on my lower legs. I stretch well before I run but they still seem to hurt. I wear knee length running bottoms and the bottom half of my legs are freezing. Would this effect my muscles?? I am unsure what to do! Any help would be appreciated!
