Running endurance?

You need to slow down. The slower you go, the further you go. Speed really doesn't matter to begin with, just try to keep going, no matter how slow it is. Walk if you need to.

I found using jog/walk worked for me. To begin with you jog for a minute and walk for a minute alternating for 30 mins and, over a few weeks, increase the jogging time until you can jog for 30 mins without stopping. You can't imagine that is possible but it is.

You could look up the couch to 5k programme which you can get in many different formats. Start off at a point you feel you can cope with and keep at it.

Breathing is often the aspect of running people struggle with the most as opposed to their legs tiring; especially if you are quite heavily built. The key is to relax as much as possible, keeping a tensed core will make breathing much more difficult and often results in sore lungs or a stitch. Try getting into a breathing pattern that your body can get used to, when running fast I inhale everytime my right foot strikes the floor or every other time if jogging.

I would say yes keep pushing yourself if all you are doing is gasping or your lungs are burning a little bit, eventually you will get better. However, becoming light headed is a sign of over exertion and you must stop running at that point as it can become very dangerous to use anymore energy (you could completely black out as your body tries to conserve energy).

Definitely keep up the work. I was right there with you at the beginning of the year. Do take walking breaks when you are having trouble breathing but try to keep it brisk. I had to retrain my body after not running for over 6 years.

If you are starting to get dizzy or seeing spots be wary that you are overdoing it. Try to hydrate regularly bot just on days you run and eat plenty of protein to keep your energy up.

It took me about 4 months of running and speed walking to get breathing back to normal I have to say lifting weight also helped me to learn how to breath too. I used to be a running snob but have to give credit to actual lifting to helping me get back out on the pavement. I highly recommend it for preventing injuries if you haven't ran regularly in a long time or ever.

your cardiovascular fitness is not very good, but will improve. Just relax, run easy.

Continue running you will get better,and running will become easier.

If you are consistent you should notice running becoming easier in less than a month.
