How fast is it?
Faster than most Virginia sprint triathlons
The fastest quarter of the 2026 sprint triathlon field finished under 1:21:21, against 1:24:35 in a typical Virginia sprint triathlon, so times here run 4 percent faster.
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.
