01·Course Characteristics
Conquering Louisville demands mastering a hot, non-wetsuit swim, a shifting-heavy bike leg, and an undulating run through oppressive Kentucky humidity.
There's still hope!
The ideal build for this course is 16 weeks, and you have 5. We'll compress the essentials into your remaining time, prioritizing the demands that matter most on this course to get you to the finish line.
02·Course by Section
A point-to-point, downstream swim in the murky green Ohio River utilizing a rolling dock-start. Sighting is straightforward through downstream bridge structures, but look out for river debris and potential wind-induced surface chop.
A single-loop lollipop course through scenic Kentucky horse country featuring continuous rolling climbs, including Halls Hill which peaks at an 8.6% gradient. The route is highly gear-heavy and finishes with a windy return leg down River Road.
A single-loop run starting on flat, exposed roads before looping through the shaded but highly undulating Scenic Loop in Cherokee Park. The course returns to a flat downtown finish featuring a final steep ramp.

Personalize this timeline04·Race-Day Execution
Prepare for temperatures rising to 34°C with a heat index up to 39°C. Utilize ice and cold water at every single aid station, and leverage the air-conditioned cooling buses along the course to drop your core temperature.
With high humidity and sweat rates, target 700 to 1000 mg of sodium per hour. Consume 60 to 90 grams of carbohydrates hourly on the bike, utilizing the on-course Maurten nutrition to prevent cramping.
Pace the rolling hills of Oldham County conservatively to avoid blowing up. Save your running legs for the steep, undulating segments of Cherokee Park by holding back on the initial flat, exposed streets.
Wear a high-performance swim skin as warm water temperatures make wetsuits illegal. Arrive at transition early to navigate the exceptionally long transition chutes at Waterfront Park.
