Keep your chest higher.

Run – Walk Combination

It’s best to start with a run-walk routine. A good place to start is with a 3-4 minute slow jog, followed by a 3-4 minute walk. Every day or so, gradually increase the running time while deceasing the walking time until you reach say 12 minutes running to 3 minutes walking. At this point you should notice a marked difference in your ability to run without getting out of breath. If you still are a little breathless, chances are you are running too fast. Slow down!

You should soon reach the stage where you can run 20 to 30 minutes without needing a break. Your anaerobic threshold is increasing! Depending on your current fitness level, age, weight etc it could take anywhere from 2 weeks to two months to reach this point. Don’t give up though - it will happen!

Nose or mouth?

Many people ask whether you should breathe through your nose or your mouth when you are running. As you start out you will be trying to get as much oxygen as possible and most people at this level breathe with both their nose and mouth. As you get fitter you’ll find that you will naturally inhale mostly through your nose and exhale through your mouth.

Deep Breathing?

Don’t try to breathe too deeply as you run or you’ll run out of oxygen. There’s a general rule of thumb that says you should be able to carry on a conversation while you are running. Again, as you get in better shape this should happen naturally.

Conclusion

Your fitness level and breathing pattern are closely related. It takes some time before you’ll be able to run consistently without getting out of breath. Simply be patient and monitor your progress to see the improvement. Keeping a running log is a great way to do this. See the link in the author bio’ below.

Try to let your body naturally sort out the breathing, but if you need to make a conscience breathing pattern, in through your nose, out through your mouth.

When I first got into running, I could only run 100 meters(1/4th of the track) I just kept pushing. I would run 1 minute, walk 1. A few days later I went 2 minutes, walk 1. Pretty soon I could run 5 then walk 1. Then I started running straight, 15, then 20, 25, 30. Now I run a 6 minute mile and I just completed my first road race(5k) with the top time and placing for my age group(and got a nifty medal!!)

Haha, so just keep practicing and train in intervals like I said:)

In economics, the terms “short run” and “long run” are relative. In the short run, there are fixed costs that do not change. In the long run, all inputs are variable, and firms and investors can move funds around to where they will be the most productive. Depending on the industry and the capital requirements, the long run could be several years, or could be as little as a few weeks. Generally, one year is considered the limits of what could be considered the short run, but there are cases in which it could stretch on longer. In the short run, there are any number of reasons that a firm might operate at a loss. It could be a strategy to win market share, or drive other competitors out of business, or it could be due to overall economic conditions. For some period, a company could even be generating cash while operating at an accounting loss, if they decide not to invest back into the business. Without some cash inflow, however, they will not have the means to replace capital equipment and make investments necessary to remain a viable concern in the long run. In the long run, a firm must generate positive cash flows if it is to survive. If it throws off less cash than consumes, it will run through the initial cash invested. Without some promise of future profitability, no new investors will step in to fund it. Eventually, all firms have to invest in their fixed capital and equipment or risk becoming unable to operate.

The biggest way to start running longer distances is by conditioning your body. You just need to build up to longer runs rather than trying to go full force right off the bat. But here are some things that really help me out every time I go running:

1. I get really bad side aches. If you train your body to breath on your left side rather than your right; this will help out a lot. If you haven't noticed, most people breath in when their right foot hits the ground and then breath out on that same foot...I guess this causes added pressure on your liver. If you start breathing in and out when your left foot hits the ground it will ease that pressure. If side stitches persist, try breathing out a couple times really hard, like you're blowing birthday candles out. This takes some getting used to, for a while I really had to concentrate on breathing like this.

2. If you get shin splints, make sure you're running flat-footed, rather than heal to toe. This will keep you from hurting your shins.

3. Take shorter, but quicker strides, rather than long ones.

4. Try running to the beat of music. This REALLY helps the time pass and keeps me from thinking "omg I've been running for 5 minutes and it feels like 5 hours!!!" Now if you're not too good at breathing on your left yet...doing that AND running to a beat is quite hard. I couldn't do it for the first couple weeks lol, but you get the hang of it.

Hope these help.

***edit***

I know someone mentioned a run/walk method; based on my personal experience, this doesn't work well for me. Yeah the thought of walking when I'm running sounds really good to me ... but I've found that if I actually stop and walk for a bit, it's so much harder for me to start back running again. That's when my side aches are the worst and seem harder to get rid of. Not sure if you prefer the run/walk method, but for me I'd rather run the whole way. I think it's the fastest way to build endurance anyway because if I run 3 miles straight once...I should be able to do it again.

just keep running, i know this sounds silly, but keep running even if you feel like your knackered keep running. there is a physical point in which a runner will reach where they will then be able to run on a high, known as a runners high, which is where it becomes easier for the runner to keep going, and be physically happy meaning that they do not feel the pain.

OR

if you cannot reach this, keep running past your point to extend you level of fitness, meaning next time you run you can run to this new level and then run longer, increasing your time running.

ALSO

listen to music, upbeat songs will give you the energy and will distract you from your tiredness.

AND

have something to eat 1-2 hours before, like a bannana, or pasta/bread (carbs) or sugar to give you energy which is released slowly (carbs) or quickly (sugar)

good luck x
