The Speedskating United Development Foundation, or the SUDF, was established in the summer of 2021 in Milwaukee, Wisconsin. The foundation is committed to developing the sport of speedskating in the greater Milwaukee area and the Midwest region.

SUDF provides financial and human resources to existing local speedskating teams, clubs, and elite training programs through training, camps, competitions, and related activities. The SUDF is aiming to create a long-term development plan for speedskating in the region to expand the talent pool and positive influence of speedskating in the nation.
