The Team Red Shamrock Trail Challenge is an annual trail running event held in Coralville, Iowa. This edition marks the 14th year of the competition, which serves to benefit the Red Shamrock Foundation. The event takes place at Coralville Creekside Park, utilizing the natural terrain of the area for its courses.

Participants can choose between two distinct trail distances:
