"All events will be scored the same. New for 2010, racer’s 2 worst scores will be dropped. This will keep the competition hot throughout the season. The winners of the 2009 Iowa Cup will receive free entry into the Iowa City Road Race and, beginning with the State Fair Criterium, the leaders of each category will receive free entry to the next race on the schedule (or next 2 races if it’s a weekend of racing)."

Cody McCullough has the early lead in Master's 40+ by being the highest placed Iowan after the first weekend of the series.
