Iowa Trail Run Series: Yellow River State Forest

The driftless region of Iowa is like no other place in the state. Run with us at Yellow River State Forest to experience a variety of terrain and beautiful views of the surrounding valleys. We'll have a half marathon, 10K, and 5K to challenge all abilities of trail runner!

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 an exclusive 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! Giveaways from sponsors!
