The Austin Pride Rainbow Run is a 5K that runs right through the streets of downtown, and this year it celebrates the theme of "Love Unites" as participants cross the finish line and giving them the option to enter a "rainbow explosion," where they will be covered head to toe with "Rainbow Magic" colored powder.  After the race, runners will be able to show their pride with a post-5K party featuring music, food and a health and wellness vendor expo.
