What Badwater 135 does to feet.
Every line below is computed from published course data or written by PR Run and labeled as such.
- Ground heat through the soleRoad surface temperature in Death Valley cooks the bottom of the foot. Thicker soles, lighter colored shoes, and regular cooling stops all buy time.PR Run field call
- Road camberHours on a cambered shoulder load one side of each foot unevenly. Switch sides of the road when it is safe to do so.PR Run field call
- Heat and sweatJuly highs reach 125 degrees F. Sweat saturates socks, skin softens, friction climbs.Course data
- Hours on feet135 miles inside a 48 hour limit. Every hour adds shear, swelling, and sock saturation.Course data
- Long aid gaps32.2 miles between stations at the widest gap. Carry what you need to fix a hot spot alone.Course data
- Night hoursA 48 hour window means hours of taping in the dark with cold hands. Practice it that way.Course data
- Downhill shearMile 54.5 to 65 drops 3,350 ft at 6 percent average grade. Toes hit the front of the shoe, heels lift.Course data
- Technical groundTechnicality 6/10. Rock strikes, side loading, and constant foot correction grind the same spots.Course data

- 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.

- 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.
Shoes
What survives this course.
Matched on terrain, technicality, and distance. Fit still beats every spec, so try them on a long run first.
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
- One hundred percent pavement at up to one hundred twenty five degrees. The road conducts heat straight through the sole.
- This is the race where blisters come from heat rather than rub. Cooling the foot matters as much as taping it.
- Crew vehicle access is continuous. There is no excuse for a foot problem going unattended for hours here.
- Educational only. Test every tape, sock, and shoe combination on long runs before race day.

FAQ
Badwater 135 foot questions.
- 01
What size shoes for Badwater 135?
Most finishers go up a full size, sometimes more. Heat and one hundred thirty five miles of pavement swell feet badly. Bring multiple pairs in increasing sizes and let your crew hand up the next one.
- 02
Where should I stop for foot care at Badwater 135?
Panamint Springs at mile 72.3, Lone Pine at mile 122.3. Those stops carry the most ground and descent behind them, so a sock change and a tape check pay for the minutes they cost.
- 03
Which section of Badwater 135 wrecks feet?
Mile 54.5 to 65 drops 3,350 ft at 6 percent average grade. That is where toes meet the front of the shoe and heels start to lift. Pretape before it, not after.
- 04
How do I keep my feet dry at Badwater 135?
July highs reach 125 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.
- 05

Plan one at every foot stop you have access to, and carry one spare pair beyond that. 135 miles inside 48 hours is long enough that dry socks are faster than the five minutes they cost.
