Adapts to your fitness, schedule & recovery every week.
Temperatures can soar above 32°C, making active cooling essential. Utilize every aid station to grab ice and cold water to keep your core temperature down, especially on the highly exposed run.
Fuel & hydration
Aim for high fluid intake of 700 to 950 ml per hour, supplemented with significant sodium and electrolytes to combat the heavy Texas heat and prevent cramping during the run.
Pacing
Conserve energy during the assisted downriver swim. Pace yourself conservatively on the outbound bike leg to manage the southern headwind, reserving strength for the steep Cameron Park hill.
Gear & logistics
A versatile mid-depth front wheel is ideal to handle windy crosswinds on the exposed country roads. Book accommodations near Indian Spring Park early to secure easy access to the transition area.
Frequently Asked Questions
What is the water temperature and wetsuit policy for the IRONMAN 70.3 Waco swim?
The water temperature in the freshwater Brazos River typically hovers between 70°F and 80°F (21°C to 26.6°C) on race day. Depending on seasonal cold fronts, this makes it a borderline wetsuit-optional or swimskin-required swim. The 1.2-mile, point-to-point course is beginner-friendly as it flows downriver with a gentle, supportive current.
How hard is the IRONMAN 70.3 Waco bike course?
The bike course is moderately challenging, featuring a single-loop route with rolling hills, false flats, and approximately 2,081 feet (634 meters) of total elevation gain. You will face heavy wind exposure, typically with a strong headwind or crosswind from the south on the outbound section, and a few steep sections on Highway 77 that require your small chainring. Keep an eye out for rough shoulders, crack lines, and potholes around the 6.3-mile, 8.1-mile, and 13-mile marks.
What is the run course profile and elevation for IRONMAN 70.3 Waco?
The run is an exciting double-loop, 13.1-mile course along the Brazos River that crosses historic bridges five times and gains between 471 and 736 feet (143 to 224 meters) of total elevation. You will encounter a short but notoriously steep and challenging climb in Cameron Park. While the park offers some tree cover, much of the pavement near the river and stadium is fully exposed to the midday sun before you finish on the historic Waco Suspension Bridge.
What weather conditions should I expect at IRONMAN 70.3 Waco?
You should prepare for warm and potentially very hot conditions, with historical afternoon highs ranging from 89°F to 94°F (31.7°C to 34.4°C) and morning lows between 53°F and 76°F (11.7°C to 24.4°C). High morning humidity during the swim often transitions into a dry, windy heat on the bike and run. Due to these high temperatures, maintaining a high fluid intake of 24 to 32 ounces per hour and supplementing with substantial sodium is critical to prevent cramping.
How should I plan my travel and lodging for IRONMAN 70.3 Waco?
The most convenient airports are Dallas-Fort Worth International (DFW) and Dallas Love Field (DAL), both located about a 1.5 to 2-hour drive from Waco, though Waco Regional Airport (ACT) also offers regional flights. Once there, staying near Indian Spring Park in downtown Waco is highly recommended for easy, walkable access to the transition area. You should book your accommodations as early as possible because local hotels fill up rapidly due to the race and nearby Baylor University events.
