Get ready to hit the trails at the Team Red Shamrock Trail Challenge on April 4, 2026, in scenic Coralville, IA. This long-standing event, celebrating its 15th anniversary, offers a unique opportunity for runners of all levels with 10-mile, 5K, and a celebratory 1500-meter fun run distances. Typical race day conditions in early April feature pleasant highs around 59F and lows near 37F, with only a 13% chance of precipitation, creating ideal trail running weather.

The Team Red Shamrock Trail Challenge takes participants through Coralville Creekside Park, utilizing a diverse course of grass, dirt single track, and paved trails, including the Cross, Flow, Clear Creek, and Woodpecker trails. The 10-mile distance is an out-and-back route, with the most challenging section being an ascent up the grassy Cross trail in the first mile. Leashed dogs are welcome to join their owners on the course, adding to the community atmosphere.

Beyond the challenging and picturesque routes, this event is a cornerstone of the No Coast Trail Series and serves a vital cause: benefiting the Red Shamrock Foundation, which supports pediatric cancer survivors. Aid stations offering water and snacks will be available at the start/finish area and near the Tom Harkin trailhead on the 10-mile course, where runners will also find flush toilets and running water. Pediatric cancer survivors receive free entry, highlighting the race's core mission. After conquering the trails, runners can enjoy a post-race gathering at Field Day Brewing Co. in North Liberty.
