Slower than most Tennessee sprint triathlons

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 July 31 the day usually runs from 70°F at dawn to 86°F in the afternoon, with measurable rain on about 47% of days. Cold snaps dip to 66°F and hot years reach 92°F.
