TrackTown Summer Series: Championship Meet

Professional track and field teams representing four American cities (San Francisco; Philadelphia; Portland, Oregon; and, naturally, New York) meet on Randall's Island to compete for glory and more than $500,000 in cash and prizes. There's also an open 5K race on the same day; all participants get admission to the professional meet as spectators. For more information, visit gotracktownusa.com.
