When i run i feel sick
When i run at a decent pace (say 8 miles per hour) i start to feel sick after half a mile and i feel like i am going to throw up after a mile. I am a pretty athletic guy and i can run sprints very well, I play football and i lift weights, but long distance running makes me feel like i am going to throw up. I drink enough water and i eat long enough before a run and i have tried every breathing technique in the book.
