I wouldn't think so. It makes your heart beat faster meaning that you can't push yourself harder without running the risk of heart trouble. It also interferes with your concentration and the effects don't really last that long and you quickly build up a tolerance.

If you were looking at something that lasted longer then you'd go with meth or ordinary amphetamine.
