Where a finish time would have placed in 2026.

Slower than most US sprint triathlons
The fastest quarter of the 2026 sprint triathlon field finished under 1:31:59, against 1:24:09 in a typical US sprint triathlon, so times here run 9 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.
Around June 26 the day usually runs from 47°F at dawn to 73°F in the afternoon, with measurable rain on about 27% of days. Cold snaps dip to 39°F and hot years reach 80°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.
