What this experiment does
Unlike the Fun famous-distance tool (race rescale into marathons and track laps), this experiment uses geographic city-to-city distances.
Run Somewhere auto-matches your year. Famous Journey lets you choose the destination.
How it works
Yearly km = weekly × 52. Percent of route = yearly ÷ journey km. Years to finish = journey km ÷ (weekly × 52).
Great-circle kilometres, not driving or hiking routes. Steady weekly volume assumed.
Frequently asked questions
Is this the Fun famous-distance calculator?
No. That Fun page rescales kilometres into marathons, 5Ks, and track laps. This experiment times geographic journeys.
Where do the city distances come from?
Rounded great-circle figures curated for the experiment catalog — good enough for jokes, not for navigation.
