Legend Phelps to make return today

American Michael Phelps, the most decorated Olympian of all-time, will make his return to competitive swimming today.

Phelps, whose 22 Olympic medals include 18 golds, has not raced since London 2012. But he is among a star-studded entry for the Arena Grand Prix in Mesa, Arizona, with the 28-year-old Phelps set to be joined by fellow Olympic medallists Ryan Lochte and Katie Ledecky.

The three-day meet has attracted more than 500 swimmers, including almost 50 members of the United States national team.
