TRAINING PROTOCOL
100-Mile Training Protocol
Distance-specific preparation, with shared foundations and explicit evidence limits.
Build on the Ultra Training Framework
01 · Editorial practice · not a validated protocol
The night changes the problem
Estimate time in darkness and the possibility of a second night, not just the distance. The plan must still work with slower movement, reduced appetite and impaired attention. A fast daytime 100K template cannot supply those decisions.
Context and evidence
02 · Editorial practice · not a validated protocol
Train repeatability, not sleep deprivation
Build manageable training around the course demands. Familiarize yourself with lights and night navigation in a short safe outing. Deliberately exhausting sleep before a long run is not a necessary proof of readiness.
Context and evidence
03 · Editorial practice · not a validated protocol
Test systems with an exit
Use a route that allows shortening the session while testing carrying, food access and planned walking. Back-to-back days can expose logistical issues, but are not established as a compulsory qualification for this distance.

Budget downhill strain
Look at where descents occur, especially after the likely onset of fatigue. Progress terrain exposure with recovery room and consider how poles, if permitted and practiced, affect your ability to manage kit and food.

Set a sleep and caffeine boundary
Map the likely first and second nights by actual cutoff and terrain. Locate staffed rest points, a safe way off course and who can check attention. Ultra sleep observations do not yield a universal nap schedule: if you cannot stay awake, repeatedly miss turns or cannot move safely, stop and seek help. A familiar caffeine plan cannot certify safe judgment.

Respond while a hotspot is small
Make dry socks and familiar supplies reachable. Inspect a developing problem at a safe stop rather than accepting hours of worsening friction. Tape is not a universally proven solution and damaged skin may need qualified care.

Arrange the journey home
Have a safe transport and sleep plan that does not depend on driving while exhausted. Leave the next training or race decision open until recovery can be assessed. Persistent or serious symptoms require professional attention.

Evidence and limits
This is an editorial planning guide, not a validated distance-specific training prescription. Shared research is discussed in the linked topic pages with source checks and limitations. Exact weekly volume, sleep timing and run/walk schedules remain individual and incompletely studied. No personal race experience or independent expert review is claimed.
