Course, distances and logistics

  • 100 miles : 13,615 ft gain
  • 50 miles : 5,395 ft gain
  • 30 miles / 50K (listed also as 32 miles) : 3,332 ft gain

Start/finish locations are split by distance: the 100-mile is associated with New Ipswich, NH; the 50-mile with Rutland, MA; the 50K / 30-mile with Spencer, MA. The race uses wave starts and seeds runners by estimated pace to manage on-course support; aid station cutoff times are based on this model. Organizers state they may hold runners who are outrunning race support to ensure food, water and medical coverage at aid stations. The main event mailing address is 1180 Turnpike Rd, New Ipswich, NH 03071. Registration details and course maps are provided by the event organizers.
