This is an official affiliate race organised independently by Zathan Simpson rather than by the championship organisation.
It starts at 10:00 a.m. on Saturday 24 October 2026 at Waters Farm in West Sutton, Massachusetts. Note that the official affiliate list gives the location as Millbury; the registrar’s West Sutton address is the current one. Entry is $125 for the 100 standard places; registration closes on 21 October. No age minimum, crew or pacer policy is published for this race, though the format’s global rules apply — no pacers, no non-competitors on the course, and no personal aid during a yard.
