• Run (13.1 miles): The half-marathon course wound through downtown, with aid stations every 2 miles and strong crowd support boosting morale.
• Transitions: Time spent in T1 (swim-to-bike) and T2 (bike-to-run) is counted, often making a difference of seconds in close races.
• Qualification: Athletes earned slots through over 70 global 70.3 events, with age-group winners and top finishers advancing.
