This is the 14th annual Team Red Shamrock Trail Challenge to benefit Red Shamrock Foundation (RSF). We are returning again to Coralville Creekside Park with a 5K and 10 mile distance. 5K awards ceremony will begin around 10:00 AM and the 10 mile awards will start around 11:15. We would like 10 mile participants to finish within 2 1/2 hours but we will not pull anyone from the course. Race will be chip-timed by Nonstop Race Management.
