The Spring Fling Criterium Series is an annual series of training races taking place at Clinton Lake near Lawrence, Kansas. The Spring Fling is one of the longest running crit series in America and the longest in the Midwest. The Spring Fling is a fun, safe, and well run event that is beginner friendly.

The race director for the Spring Fling Criterium Series is Revolution Racing owner Jim Whittaker.

Due to a late-winter snowstorm, the opening round of the series has been postponed, and each race has been pushed back one week. New dates are March 5, March 12, March 19, March 26, and April 2.
