Will your pace beat the cutoff?

Some races enforce their cutoff on the gun clock rather than your chip time. Check what your race says, then see where you land against whichever clock it uses.

Already know your race? See what it publishes about its cutoff, sweep and walker policy.

Your pace
Show pace in
Walking pace
The pace you can hold for the whole distance, not your best mile.
The race
Published cutoff
Your number, not ours. Use your corral's published offset. If the race uses waves and you don't know yours, ask them — don't enter zero.
Checkpoint cutoffs
Intermediate cutoffs are often buried in the participant guide. A race can be comfortable overall and still pull you at mile 20.
Your assumptions
Almost nobody walks the measured racing line. This is our assumption, not race data.
Toilets, aid stations, photos, shoelaces. Spread evenly across the distance for checkpoint arrivals.

What this calculation assumes

    This is arithmetic on a constant pace. It does not account for fatigue, heat, hills, injury, or anything else that happens after mile 18. Treat the buffer as the best case, not the expected case.
