start out slow for about a month or so and then you can intensify the running

Ive been jogging on and off for 2 years now. My endurance is half decent. My knee usually gives out before my lungs do, around the 4-5 mile mark.
Im afraid the only thing to do is be consistant and build up a tolerance to the sprints. ![]() |

i wish i had ur endurance to be able to run 4-5 miles without nearly fainting because im not taking in enouph air

). Keeps the body guessing. Switching back and forth between that and afternoons has helped.

The biggest factor in increasing your ability to handle extreme loads like sprinting is by first boosting your endurance. If you frequently run long distances for 30 minutes or more and gradually increase your speeds the more you do it, it will greatly increase your sprinting abilities.
When I was in technical training school for the air force I ran 1.5 miles 2 days on 1 day off for the entire time, trying to get my time down for the eval but my improvements were minimal because I never did any distance running. Currently I'm running 7.5 miles in 50 minutes and my 1.5 mile run is down into the 8 minute range. The distance runs basically conditioned my body to be a running machine, which benefited my shorter distance power runs immensly. With all of that said, you're puking because your body can't handle what you're doing to it, you haven't properly trained yourself for it. I see so many guys in our eval runs puke, and they're the ones I never see running in their free time. |

Depends if you're trying to improve cardio in terms of heart health or if you're trying to improve cardio so that you can go over threshold with a higher power output for exercise performance. If you're constantly driving your heart rate to 95% of its maximum over and over again for short bursts you may not get the results you're looking for.
