I study the possibility of constructing an observationally viable scenario where both early inflation and the recently detected accelerated expansion of the universe can be explained by using a single scalar field associated with the tachyon. The reheating phase becomes crucial in enabling us to have a consistent cosmology and also to get a second accelerated expansion period. A discussion using an exponential potential is presented.
