Every line below is computed from published course data or written by PR Run and labeled as such.

  • Alpine wet and coldCreek crossings and storms at altitude, then a cold night. Dry socks in every bag, and warm feet before taping.PR Run field call
  • Hours on feet100 miles inside a 37 hour limit. Every hour adds shear, swelling, and sock saturation.Course data
  • Downhill shearMile 15 to 21.5 drops 3,600 ft at 10.4 percent average grade. Toes hit the front of the shoe, heels lift.Course data
  • Total descent load18,100 ft of cumulative descent. Nail beds and forefoot pay for all of it.Course data
  • Heat and sweatJuly highs reach 80 degrees F. Sweat saturates socks, skin softens, friction climbs.Course data
  • Cold and numb toesLows near 25 degrees F. Wet feet plus cold is how trench foot and numb toes start.Course data
  • Technical groundTechnicality 8/10. Rock strikes, side loading, and constant foot correction grind the same spots.Course data
  • Altitude swellingHigh point near 13,104 ft. Feet swell at altitude, so shoes that fit at the start pinch by dark.Course data
  • Long aid gaps16 miles between stations at the widest gap. Carry what you need to fix a hot spot alone.Course data
  • Night hoursA 37 hour window means hours of taping in the dark with cold hands. Practice it that way.Course data

Downhill shear

Where gravity works on your toes.

Sustained descents pulled straight from the elevation profile. Pretape before these, not after.

What High Lonesome adds to the standard kit.

  • 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.
  • Extra dry socks and a towelCold wet feet break down faster than cold dry feet.
  • 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.
  • Moleskin for pressure pointsRock strikes and side loading build hot spots off the usual map.

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

  • The Continental Divide Trail section runs high and exposed, with creek crossings and afternoon weather.
  • Cold nights at altitude after a wet day is the combination that takes toes numb.
  • Educational only. Test every tape, sock, and shoe combination on long runs before race day.

A single sheet your crew reads at two in the morning: the stop script, the mandatory kit, and the calls that pull the runner. Print it, laminate it, staple it to the drop bag.

FAQ

High Lonesome foot questions.

  1. 01

    Where should I stop for foot care at High Lonesome?

    Aid 2 at mile 24, Aid 6 at mile 72, Aid 7 at mile 84. Those stops carry the most ground and descent behind them, so a sock change and a tape check pay for the minutes they cost.

  2. 02

    Which section of High Lonesome wrecks feet?

    Mile 15 to 21.5 drops 3,600 ft at 10.4 percent average grade. That is where toes meet the front of the shoe and heels start to lift. Pretape before it, not after.

  3. 03

    How do I keep my feet dry at High Lonesome?

    July highs reach 80 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.

  4. 04

    Do I need dry socks for the cold sections of High Lonesome?

    Lows near 25 degrees F. Wet feet plus cold is how trench foot and numb toes start. Put a dry pair in every bag you will see after dark and warm your feet before you tape.

  5. 05

    How many sock changes for High Lonesome?

    Plan one at every foot stop you have access to, and carry one spare pair beyond that. 100 miles inside 37 hours is long enough that dry socks are faster than the five minutes they cost.

  6. 06

    What goes in my vest for High Lonesome?

    16 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.

  7. 07

    How do I stop blisters at High Lonesome?

    Start from the biggest threat on this course. 100 miles inside a 37 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.

  8. 08

    What foot care kit should I pack for High Lonesome?

    Beyond the standard kit, this course calls for powder and a moisture barrier, pretape for toes and heels, extra dry socks and a towel, vest foot kit you can use alone, light you can tape by, half size up in the crew bag, moleskin for pressure points. Sweat is the friction multiplier on this course.

  9. 09

    What shoes work for High Lonesome?

    66% trail / 27% jeep / 7% paved at technicality 8/10 points toward Nike Zegama Trail, Brooks Cascadia 19, Brooks Cascadia 19. Whatever you pick, race it on a long run first and leave room for feet that swell over the back half.
