IRONMAN 70.3 Chattanooga 2025
Race-day note: The swim was cancelled due to dangerously high Tennessee River flow rate (forecast to exceed 50,000 CFS, well above the safe ~20,000 CFS threshold) — a joint call by TVA, the National Weather Service, and Hamilton County Emergency Management, announced the day before the race. Athletes started with a time-trial bike start instead. swim_time_seconds is NULL for the whole field; total time is not comparable to a complete 70.3 and is excluded from Best/Avg 70.3 calculations for this reason.
