How your pace lands against this race

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 structureWave 1 (+0 min); Wave 2 (+25 min); Wave 3 (+60 min) sourceOffsets are measured from the Wave 1 start at 07:35, the first start for non-professional participants. The professional start is 07:30 and the wheelchair and handcycle starts are earlier still. The sweep follows the last starter, and the last individual to cross is later than the 08:35 wave 3 gun by however long that corral takes to clear — which is not published. Using 60 minutes therefore understates the sweep's head start, which is the conservative direction.
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.
