How fast is it?
Slower than most Wisconsin sprint triathlons
The fastest quarter of the 2026 sprint triathlon field finished under 1:45:01, against 1:29:49 in a typical Wisconsin sprint triathlon, so times here run 17 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 September 19 the day usually runs from 57°F at dawn to 74°F in the afternoon, with measurable rain on about 28% of days. Cold snaps dip to 47°F and hot years reach 83°F.
