Cruel Jewel 100 runs 106 miles in the North Georgia mountains, mostly on the Benton MacKaye Trail. 33,000 feet of climb — comparable to Hardrock vert on a single-loop Eastern course. 48-hour cutoff. Held in mid-May. The Southern 100 — and one of the most underrated, hardest 100-milers in American ultrarunning.

The course

Out-and-back on the Benton MacKaye Trail through the Cohutta Wilderness and Big Frog Wilderness. Steep climbs (some 25%+ grades), dense Appalachian hardwood forest, technical single-track, exposed ridge sections. The trail is rooty and rocky in places, runnable in others. Vert per mile (311 ft/mi) puts it firmly in mountain-ultra territory despite being on the East Coast.

By the numbers

  • Distance: 106 miles (out-and-back)
  • Vert gain: 33,000 ft
  • Vert per mile: 311 ft/mi (high mountain-tier)
  • Highest point: ~4,400 ft
  • Cutoff: 48 hours
  • Date: Mid-May

How to qualify and enter

Open registration with a 50-mile qualifier required. Lower-profile race; less competitive than the Hardrock-tier qualifiers. Worth knowing if you want a serious mountain-tier 100 without lottery wait.

The Cruel Jewel difference

The combination of vert (33,000 ft) and Appalachian terrain (rocks, roots, mud) makes Cruel Jewel as hard as Hardrock by some measures. The 48-hour cutoff is generous because race directors know how slow the course is. Most finishers run it 38–46 hours. Sub-30 is elite-only.

Gear strategy

  • Vest: 12L. UltrAspire Zygos 5.0 — long aid station gaps.
  • Shoes: aggressive lugs essential. Tecnica Magma or Hoka Speedgoat. Most finishers swap shoes 2-3 times.
  • Layers: long sleeve + light shell. May in North Georgia is humid but ridges can be cold and windy.
  • Trekking poles: highly recommended for the steep climbs.
  • Headlamp: primary + spare. Two nights potentially in play.

The Cruel Jewel experience

Most finishers describe Cruel Jewel as the most underrated 100 in America. Not as iconic as Western or Hardrock; not as commercialized. The course is genuinely punishing. The trail community in North Georgia is small, devoted, and welcoming. The race director's pre-race briefing famously begins: "This race is named correctly."
