- Powder and a moisture barrierSweat is the friction multiplier on this course.
- Pretape for toes and heelsLong descents load the front of the shoe and lift the heel.
- Vest foot kit you can use aloneThe widest gap is long enough that a hot spot becomes a blister before the next station.
- Light you can tape byTaping in the dark with cold hands is a different skill than taping at your kitchen table.
- Half size up in the crew bagFeet swell over the back half. A tight shoe at midnight ends races.

Crew
What your crew needs on paper.
Two plates. On the left, the race-specific notes that never make it into the standard script. On the right, the printable card your crew reads at two in the morning under a headlamp.
Race day notes
- Crux near Manoa Cliff and the muddy Tantalus ridges near mile 65. Plan foot work before the field splits.
- Surfaces: 90% trail / 10% dirt road. Match lugs and tape adhesion to the dominant surface.
- Air band 55°F to 85°F. Crew should carry dry socks and skin lube when heat or rain is in range.
- Cutoff 36 hours. Longer stops only where the schedule has real buffer.
- Educational only. Test every tape, sock, and shoe combination on long runs before race day.

FAQ
HURT foot questions.
- 01
Where should I stop for foot care at HURT?
HURT mile 61 at mile 61.2, Finish Hawaii at mile 102. Those stops carry the most ground and descent behind them, so a sock change and a tape check pay for the minutes they cost.
- 02
Which section of HURT wrecks feet?
Mile 97.5 to 102 drops 1,400 ft at 5.8 percent average grade. That is where toes meet the front of the shoe and heels start to lift. Pretape before it, not after.
- 03
How do I keep my feet dry at HURT?
January highs reach 85 degrees F. Sweat saturates socks, skin softens, friction climbs. Change socks at every stop you can, run powder or a moisture barrier, and lean forward when you dump water on your head so it misses your shoes.
- 04
How many sock changes for HURT?
Plan one at every foot stop you have access to, and carry one spare pair beyond that. 102 miles inside 36 hours is long enough that dry socks are faster than the five minutes they cost.
- 05
What goes in my vest for HURT?
20.4 miles between stations at the widest gap. Carry what you need to fix a hot spot alone. Tape, two wipes, a blister patch, and a small tube of lube covers a hot spot without waiting for crew.
- 06
How do I stop blisters at HURT?
Start from the biggest threat on this course. 102 miles inside a 36 hour limit. Every hour adds shear, swelling, and sock saturation. Fit the shoe with room for swelling, pretape the spots that have blistered on you before, keep grit out, and change socks at every stop you have access to. Blisters come from pressure, friction, and moisture, so remove whichever one this course hands you the most of.
- 07
What foot care kit should I pack for HURT?
Beyond the standard kit, this course calls for powder and a moisture barrier, pretape for toes and heels, vest foot kit you can use alone, light you can tape by, half size up in the crew bag. Sweat is the friction multiplier on this course.
- 08
What shoes work for HURT?
90% trail / 10% dirt road at technicality 5/10 points toward Inov-8 Trailfly Ultra G 300, Nike Zegama 2, Topo Athletic Ultraventure 4. Whatever you pick, race it on a long run first and leave room for feet that swell over the back half.

Train for it
Feet get you to the finish. The plan gets you there on the clock.
Foot care is one system on HURT. Climbs, descents, heat, fueling, and cutoffs are the rest of it.
