How fast is it?

Slower than most US sprint triathlons

The fastest quarter of the 2026 sprint triathlon field finished under 1:44:05, against 1:24:09 in a typical US sprint triathlon, so times here run 24 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 June 12 the day usually runs from 62°F at dawn to 74°F in the afternoon, with measurable rain on about 19% of days. Cold snaps dip to 57°F and hot years reach 81°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.
