The first race of the season is Chico Classic and will take place at Black Butte Lake the first weekend in May. Black Butte lake is located west of Interstate 5 at the Orland exit. The course features long windward/leeward legs and a short tight reach across the north end of the lake. Winds are either northerly or southerly, blowing down the axis of the lake. Three or four races are held on Saturday, and two races on Sunday. The course is shortened for light winds. For further information go to Chico Classic - May 1-2.
