No calculator for this race

This race runs fixed time limit and a rolling sweep. A single finish estimate cannot answer both questions at once — you can stay ahead of the sweep and still finish outside the time limit, or the reverse, depending on your wave. Until the sweep anchor is verified against the published wave times, we will not compute a figure we cannot stand behind.

Use the calculator on the homepage against the 6:30 time limit, and read the sweep row above separately.

What the race publishes

Cutoff mechanismFixed time limit and a rolling sweep
Time limit6:30 on chip time sourceEvent time requirement is 6:30 start line to finish line. Official times for non-professional participants are net time. Net times exceeding 6:30 may not be recognised as official finishers. The rules hedge with "may" on all three consequences.If you miss it: may not receive an official time · may be removed from the course · loses full on-course support
Required pace at the limit14:52 per mile · 9:15 per kmDerived from the published limit over the official distance. Your own required pace depends on your start delay and planned stops.
Course sweep15:00 per mile, anchored to the last starter sourceThe official end vehicle starts following the last starter and maintains a 15-minute per mile pace. Because it is anchored to the last starter rather than the gun, an early-wave participant has more physical course access than the 6:30 net limit implies — and none of that extra room counts toward official finisher status.If it catches you: may be removed from the course · loses full on-course support
Intermediate cutoffsNot publishedSearched: Event rules page. Course closure is governed by the end vehicle rather than stated checkpoint times. 2026 participant guide not yet checked.
Start structureNot publishedSearched: Rules confirm corral assignment determines start time, but wave start times were not verified from the official race-day timeline for this record. Required before the sweep anchor can be computed.
Walkers explicitly allowedNot publishedSearched: Rules require capability of finishing within 6:30 and an approximate 15:00/mile pace, but make no statement about walking as such.
