IRONMAN 70.3 Waco is about more than just the swim-bike-run. With so much to do in the central-Texas town—from the Cameron Park Zoo to the Mammoth National Monument fossil site—this triathlon is the ultimate race-cation in the making. But back to the important things. The swim takes place in the Brazos River and passes below the picturesque and historic Suspension Bridge before continuing onto the bike—a single-loop course through the Waco wetlands. With a gradual incline and fast descent, it's one of the more appealing 70.3 bike segments on the half IRONMAN schedule. Finally, athletes wrap up their race on the double-loop run course, which crosses over the Brazos River and through Cameron Park before finally finishing on the oldest suspension bridge in the southwest.
