1 event in Urbandale, Iowa

Run along the picturesque shore of Saylorville Lake through Jester Park on a variety of trail surfaces including gravel, dirt, and grass. New in 2026, we're doing an enduro! How many times in 10 hours can you do the 3.1 mile loop?

Or get ready for a great 5K or 10K and don't forget to wave at the buffalo as you run by!

The Iowa Trail Run Series is not about spending a bunch of cash for no reason. You'll get a great race with clear marking and course support, with basic timing, a cool custom bib, and a rotating race item such as a BUFF, socks, a stocking cap, coffee mug, and aluminum water bottle. Signing up for the entire series includes a series gift! Do you want a really soft and comfy tri-blend shirt with one of our Animal Icons? Great! Add one during your registration. We know some people have enough stuff in their closet and others may want to commemorate the day! Plenty of post-race food to refuel! Games!
