Build a system that can last six days
6-Day Races
A 144-hour fixed-time event where sustainable routines and recovery choices matter across nearly a full week.
How the Format Works
A six-day race gives runners 144 hours to accumulate distance, usually on a short measured loop with a nearby support area. Movement, meals, sleep, clothing, hygiene, and foot care all become parts of one continuous race system.
This format magnifies small failures. Sustainable effort, repeatable routines, early problem-solving, and the willingness to change the plan matter more than forcing an ideal daily mileage schedule.

6-Day FAQs
Do runners sleep during a six-day race?
Yes, runners can rest and sleep, but the timing and duration vary widely. A useful plan includes multiple safe options and changes with alertness, symptoms, goals, weather, and support rather than forcing one universal schedule.
Should a runner complete a 24-hour race first?
Prior fixed-time experience can reveal pacing, food, foot-care, and support problems at a lower duration, but it is not a universal qualification. Race rules, health, training background, and event logistics still determine readiness.
What matters most in a six-day race?
A sustainable system matters: conservative effort, repeatable meals, sleep options, hygiene, early foot care, weather management, and clear medical escalation. One ambitious daily-distance target cannot replace those processes.
