I am new to running and now been running for 3 weeks. Can anyone can give me any useful tips on how to breath properly while running, what I should be eating (trying to lose about 8lbs - a stone in weight) and how long after eating should I leave it before I go out running. I seem to be really struggling with breathing in through my nose and out through my mouth. At the moment I am managing to run for just over 3 miles 4 nights a week (not very fast I might add, doing this in about 35mins give or take a few minutes either way). My breathing is ok for the first 15 mins and then its like I am doing a Lamar’s class (quick short breaths) Any tips would be really useful.
