There is no cut-off point in the 5-mile race.

Runners who miss the time limit at 14 km (12:05 PM), 15 km (12:14 PM), or 16 km (12:23 PM) will be picked up by a sweep bus.

Anyone finishing after the 1:15 PM time limit must remove their race bib and stop racing.

Delaying after passing the second cut-off point is particularly prohibited.

Eligibility is half marathon: runners aged 18 or over who can finish within 2 hours 30 minutes;

for the 5-mile race, participants must be high-school age or older and able to finish within 1 hour.
