World record holders Michael Phelps, Aaron Peirsol, Ryan Lochte, Brendan Hansen, Ian Crocker, Natalie Coughlin, Katie Hoff and Kate Ziegler are set to make the Missouri Grand Prix sizzle. The meet, on February 15 to 18 at the Mizzou Aquatic Center in Columbia, marks the start of reality in Olympic year: gone is the small pool and the even titchier yards ponds, and here comes the first long-course outing of the year for some of those who will lead the way in Beijing come August.

The third stop of the Grand Prix Series will also feature supermom Dara Torres, and fellow Olympians Erik Vendt, Peter Vanderkaay, Mark Gangloff, Neil Walker, Scott Usher, Amanda Beard, Kaitlin Sandeno, Tara Kirk, Rachel Komisarz, Kara Lynn Joyce, Margaret Hoelzer and Carly Piper, as well as world champion Leila Vaziri.

The top scoring swimmer at the culmination of the eight-meet Toyota Grand Prix Series will be awarded $20,000, courtesy of Toyota and USA Swimming.
