What to Expect at Hanging Man

Hanging Man is a Half Ironman (70.3 mi) ironman 70.3 held in Danbury, NC, US. Based on 5 years of historical weather data, athletes can expect median race-day temperatures around 58°F.

Temperatures at Hanging Man typically range from 47°F to 68°F. This falls in the favorable range for endurance performance. Standard fueling and hydration targets should work well, though individual sweat rates still vary — a sweat test gives the most accurate picture.

A 70.3 sits in a nutritional sweet spot: long enough that fueling matters, but short enough that gut fatigue rarely becomes the limiter. Front-load calories on the bike and shift to a lighter fueling approach on the run. Most athletes target 60–80g of carbs per hour on the bike and scale back slightly for the half marathon.

We do our best to keep race details accurate and up to date, but things can change and occasionally we simply get something wrong.
