  • Every entry includes a technical shirt, finisher's medal, post-race food, overall and age-group award eligibility, and on-course aid stations
  • Remote venue with no concessions at Lovell Canyon
  • runners are advised to come self-sufficient with their own food, water, shade and necessities, while on-course provisions help keep runners cool
