Event Overview
Taking place in early June 2026, IRONMAN 70.3 Des Moines has quickly become a favorite in the midwest circuit. Des Moines offers a surprisingly vibrant urban backdrop combined with the rolling greenery of Iowa’s countryside. The race is known for its incredible volunteer support and a finish line atmosphere in the heart of downtown that rivals the full-distance championships. The weather is typically humid and warm, making heat management a primary factor for success.
Course Details & Terrain
Swim (1.2 Miles): The swim takes place in Gray’s Lake. It is a single-loop, counter-clockwise course. The water is generally calm, but visibility can be low. Expect a rolling start which helps manage athlete density.
Bike (56 Miles): This is where the race is often won or lost. The course takes athletes out of the city and into the rural roads of Iowa. While people assume Iowa is flat, this course is 'relentlessly rolling.' There are no massive mountains, but the constant short, punchy climbs add up to roughly 1,800 feet of gain. The wind is a significant factor here; expect a headwind on the return leg into the city.
Run (13.1 Miles): The run is a flat and fast multi-loop course around the lake and through the downtown area. The lack of shade is the primary challenge. You will be running on asphalt, which can radiate heat during the midday sun.
Who Should Enter? (Beginners vs. Experienced)
For Beginners: The swim is very beginner-friendly due to the calm lake water. The bike course is challenging but manageable for those who have trained on varied terrain. It is an excellent 'first 70.3' for those living in the Midwest.
For Experienced Athletes: This is a 'power' course. If you can hold a high-wattage aero position on a rolling terrain, you can post a very fast bike split. The flat run course allows for a blistering half-marathon time if you have the cooling strategy to handle the Iowa humidity.
Coach Raye's Race-Day Pro Tips
- The Wind Shadow Strategy: On the bike, pay close attention to wind direction. Iowa winds are sustained. If you are struggling on the out-bound leg, don't panic—you’ll likely have a tailwind on the way back. Stay in your aero bars as much as possible to minimize drag.
- Core Temperature Control: Des Moines in June is humid. Use the aid stations on the run for more than just drinking; pour water over your head and tuck ice into your tri-suit or hat to keep your core temperature down.
- Gearing Choice: Ensure your bike is fitted with an 11-28 or 11-30 cassette. You want to be able to spin up the short rollers rather than 'mashing' the pedals, which saves your glycogen stores for the run.
