Get ready for an exciting day of outdoor adventure at the Iowa Trail Run Series: Annett Nature Center on Saturday, August 16th, 2025! Located in the picturesque Indianola, Warren, this event promises a beautiful late summer run through the stunning landscape of Annett Nature Center, featuring gravel paths, dirt trails, and vibrant prairie grass. Participants will have the chance to choose from various race distances, perfect for runners of all skill levels.

Not only will you enjoy a fantastic race experience with clear course markings and dedicated support, but you'll also contribute to a good cause, as $3 from every registration goes to the Friends of Warren County Parks. Plus, each runner will receive a custom bib and a rotating race item, such as a BUFF, socks, or a coffee mug! If you’re looking to enhance your experience, a soft tri-blend shirt with one of our Animal Icons is available for purchase. After crossing the finish line, refuel with plenty of post-race food and enjoy games and giveaways from our generous sponsors. Don't miss out on this opportunity to connect with nature and fellow runners in a fun and friendly atmosphere!
