Protect the parts that end races
Feet, Injury & Recovery
Blister prevention, shoe rotation, toenail problems, chafing, sleep deprivation, and how to recover from the damage.
Feet, skin, and recovery are not side topics in multiday running. Blisters, swelling, chafing, sleep debt, and small mechanical problems can decide the race long before your aerobic fitness runs out.
Use this hub to build prevention habits before race day and a simple triage mindset for when something starts to go wrong mid-race.
Blister Prevention for Ultramarathons — The Complete Guide
Evidence-based blister prevention strategies for ultramarathons and multiday races. Covers sock systems, taping methods, lubrication, shoe fit, and mid-race blister management.
What to Focus On
Blister Prevention
Reduce friction, moisture, pressure, and late-race swelling before they become race-limiting.
Shoe Rotation
Use different shoes and sock changes to manage swelling and pressure points over long events.
Body Stress and Recovery
Understand what happens to muscles, joints, gut, brain, and immune system during long ultras.
Common Questions
When should you treat a hot spot?
Immediately. A small hot spot is easy to tape; a full blister can change your gait and create bigger problems.
Why bring larger shoes?
Feet often swell during long events. A half-size or full-size backup can reduce pressure when your normal race shoe gets tight.
Is pain always a stop signal?
No, but sharp, worsening, one-sided, or altered-gait pain deserves caution. Multiday racing rewards early problem-solving, not denial.
