Michael Phelps looking to compete in 2016 Rio Olympics

Legendary swimmer Michael Phelps is aiming to compete in his fifth Olympics when the games are hosted in Rio de Janeiro, Brazil in 2016. 

The 18-time Olympic gold medalist will not swim in the 2015 World Championships in Russia due to a punishment handed down by U.S. Swimming's governing body.

Phelps has attended an inpatient alcohol rehabilitation program after a DUI arrest in September. It was his second impaired driving charge in a 10-year stretch.

By the time the games roll around, Phelps will be 31 years old.
