Is crew access allowed on the 100K course?

Yes, crew access is allowed on the 100K course. Crew is allowed on the course to provide support outside of aid stations: one crew vehicle per participant, or one vehicle per group of runners. Crews must wait to assist their runners until after the official check-in, follow the instructions of aid station personnel, and keep to one vehicle per runner at all checkpoints except the start/finish area. Motor homes are not permitted at any checkpoints. Do not drive down level B (minimum maintenance) roads under any circumstances; towing fees fall on the crew or driver. A crew that disregards parking instructions, race rules, directions or requests from race officials gets the runner disqualified.

Are drop bags allowed on the 100K course?

Yes, drop bags are allowed on the 100K course. Drop bags are allowed at any of the manned aid stations. Run management carries them to those stations for crewless runners, and asks runners with a crew not to overload volunteers with unnecessary bags. Drop bags must be securely tied, labeled with the runner's name and entry number, and brought to packet pickup on Friday; none are collected on race day. Each bag must fit through a 6 by 8 inch opening and be no longer than 16 inches, one bag per aid station, no paper bags or glass bottles, no perishable items. Pacers are not allowed drop bags. Bags are returned to the start/finish area when the aid stations close, and must be claimed by the end of the event on Sunday.

Are pacers allowed on the 100K course?

Yes, pacers are allowed on the 100K course. A pacer may join starting at mile 42. Pacers are allowed after the 42-mile aid station. One pacer at a time, as many pacers as you wish over the day. Pacers may be picked up only at aid stations and approved crew points, must enter and leave each aid station with their runner, and may not carry supplies for anyone but themselves. Muling is forbidden and no mechanical or physical assistance may be given to the runner.

What is the cutoff time for the 100K course?

The overall time limit for the 100K course is 18 hours from the start.
