Tour de Fat Nothing goes together like bicycles and beer. At least that’s what New Belgium Brewing’s traveling tour wants us to think. The fest features a costumed bike parade, the famous car-for-bike swap, circus performers, and music from the Roots, not to mention tons and tons of beer. Proceeds benefit West Town Bikes. Sat 7/29, 4-9 PM, Hunington Bank Pavilion, 1300 S. Linn White, newbelgium.com/tour-de-fat, $25, free for kids 12 and under.
