You were definitely right about breathing through the nose and out the mouth. I trimmed almost 45 seconds off my run time, when I tried that today. I figured my breathing was holding me back, it does not feel natural but works surprisingly well. My leg muscles did not feel anywhere near as tired as they usually do. I could not keep up that breathing the whole time, a little more practice and I should be able to run a bit faster. Thank you for the help!
Figure I will add my update today after reading this at work.. I cannot agree with you any more bro... I did the exact same thing today and got the same results.. The breathing felt a little abnormal but I did not feel nearly as winded or fatigued as I usually do nor did I feel the cramping in my calves as much.. Instead of doing an all out jog/time run like I usually do I did alot of sprints... I would sprint a few hundred feet then walk some..alternating.. I definitely felt more energy and felt that I could do more. For my workout I took Jynx's advice and hit up some leg exercises at very low weight but high reps... My calves feel awesome right now (By awesome I mean god damn are are the sore haha) But in the good way... I think I am going to hit the track again tommorow and try for 3 miles or maybe go hit up a swim! Thanks for the help guys.. I am def. on the road to improvement
