==Description==
'''Second wind''' is a phenomenon in distance running, such as [https://en.wikipedia.org/wiki/Marathon marathons] or road running (as well as other sports), whereby an [[athlete]] who is too out of [[breath]] and tired to continue suddenly finds the [[strength]] to press on at top performance with less exertion. The [[feeling]] may be similar to that of a "runner's high", the most obvious difference being that the runner's high occurs after the race is over. Some scientists believe the second wind to be a result of the [[body]] finding the proper [[balance]] of oxygen to counteract the buildup of [https://en.wikipedia.org/wiki/Lactic_acid lactic acid] in the muscles. Others claim second winds are due to [https://en.wikipedia.org/wiki/Endorphin endorphin] production, while still others believe it to be purely [[psychological]].

Documented [[experiences]] of the second wind go back at least 100 years, when it was taken to be a commonly held fact of exercise. The [[phenomenon]] has come to be used as a [[metaphor]] for continuing on with renewed energy past the point thought to be one's prime, whether in other sports, careers, or life in general.[https://en.wikipedia.org/wiki/Second_wind]
