FIBArk stands for "First in Boating the Arkansas"—it's a three-day festival held in Salida, Colorado that started in the 1950s. The history actually began in 1949 when two friends bet each other who'd win a race from Salida to Cañon City on the Arkansas River. Since that race almost killed both contestants, the race was shortened in subsequent years to about 26 miles of whitewater from Salida to Cotopaxi. It became a community-wide festival. Today the festival draws over 10,000 people yearly, around the 3rd week of June, and includes a variety of events on the river and in town. The event has grown from a single boating race to now include biking, running, and other races. The portion of the river where the majority of the races are held runs through downtown Salida, keeping the event close to all of the other activities and festivities offered downtown during the festival.
From modest beginnings with only 23 competitors, this festival has grown to showcase more than a hundred competitors each year and now includes live music, foot and bike races, and a parade.
