How fast is it?
Slower than most Wisconsin sprint triathlons
The fastest quarter of the 2026 sprint triathlon field finished under 1:39:22, against 1:29:49 in a typical Wisconsin sprint triathlon, so times here run 11 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.
