While we won't be providing official pacing groups for the race due to our size, we enthusiastically welcome personal pacers for both the 50 and 100-Mile events. Personal pacers can join 50 mile participants after the 30 mile mark and 100 Mile runners after the 50 mile mark (approximately halfway points). Each pacer must pay a $15 fee that covers park entry, administrative costs, and an official pacer bib. Pacers need to sign a waiver and wear their designated "PACER" bib while on course. Runners are responsible for arranging their own pacers.
