Hall-of-Famer George Brett will captain one of three fundraising teams that have formed for the MLB All-Star Game Charity 5K & Fun Run presented by Nike, set to take place July 8 in downtown Kansas City.

Brett, whose No. 5 jersey was retired by the Royals after he spent his entire 21-year career in Kansas City, will lead the "Brett 5 Team." Meanwhile, the two other teams will be anchored by three-time All-Star pitcher Jeff Montgomery ("Monty's 5K Crew") and five-time All-Star and current MLB Network analyst Mike Sweeney ("Sween Team").

Major League Baseball will donate all of the net proceeds from the event to a trio of charities supporting cancer research -- Prostate Cancer Foundation, Stand Up To Cancer and the Greater Kansas City Affiliate of Susan G. Komen for the Cure.

The team aspect of the race comes into play for participants who register online by June 20th. Each participant that enters a team code -- "Brett", "Monty" or "Sween" -- will receive a $5 dollar discount off the original registration cost of $30 for adults or $25 for children 12 and under.

The event will be an officially-timed race, beginning at 7:30 a.m. CT in Kansas City's Power and Light District. A family-friendly one-mile Fun Run will begin a half hour later. All registered finishers of the races will receive a commemorative All-Star medal and T-shirt. The course will feature appearances by MLB legends, mascots and celebrity guests.

This will mark the third such event, with All-Star Game Charity 5K & Fun Run events also taking place previously in St. Louis (2009) and Anaheim (2010).
