Hop into a costume, saddle up your bike and pedal over to Ann Morrison Park for the annual Tour de Fat, New Belgium Brewing's traveling celebration of all things bicycle—and beer. Along with a parade, fashion show, races, games and contests, catch live music from groups like Sister Sparrow and The Dirty Birds, Fire Leopard, Honeymoon Cabaret and more. Of course, there will also be plenty of food and beer on hand with special tappings of New Belgium brews. Entry is free, but donations benefit Boise Bicycle Project. Donations can be given by preregistering online, with Tour de Fat patches, sunglasses and frog lights offered as thank-yous. Merchandise sales benefit the Treasure Valley Cycling Alliance and beer sales go to the Southwest Idaho Mountain Biking Association.
