Victor used to run marathons when he was younger, but now that he is older, he enjoys coaching a local track team. This situation is consistent with theory.

Continuity theory

Explanation: the continuity theory of aging holds that,  middle-aged and older adults attempt to preserve and maintain existing internal and external structures. In this they use strategies tied to their past experiences of themselves and their social world and as such, personality and basic patterns of behaviour of the individual remain unchanged as they grow old. Victor's situation is consistent with this theory as he maintains the same experience he had when younger which is his love for track events.
