3 laps, 18 miles/lap according to my garmin (2 miles short)
Based on 54 miles, actual pace was 19.5mph
First half of the course was relatively flat, second half was hilly, with quick drops and immediate climbs back up. More hills than I'm used to as I mostly have slow gradual climbs and decents in central IL. The last 5-6 miles was into the wind.
