How fast is it?

About average for US sprint triathlons

The fastest quarter of the 2026 sprint triathlon field finished under 1:25:45, against 1:24:26 in a typical US sprint triathlon, so times here are about average.

  • Olympic Triathlon: Slower than most US olympic triathlons. The fastest quarter of the 2026 olympic triathlon field finished under 2:49:34, against 2:43:48 in a typical US olympic triathlon, so times here run 4 percent slower.

Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.

Typical race-day weather

Around May 9 the day usually runs from 44°F at dawn to 60°F in the afternoon, with measurable rain on about 40% of days. Cold snaps dip to 36°F and hot years reach 73°F.

Based on 75 days within a week of the date over the last 5 years, from historical weather for the start area. Not a forecast.
