Example

Example: A runner may claim an FKT after completing a known mountain loop with public GPS data faster than the previous documented attempt.

Why it matters

FKT culture depends on route clarity, evidence, and honesty because there is usually no timing mat or official race director.

How runners use it

Before attempting an FKT, read the route rules, record clean GPS data, document support style, and respect access, weather, and safety constraints.
