What this experiment does
This experiment multiplies a curated film-marathon runtime by the speed implied by your pace.
Runtimes are approximate theatrical (or extended) totals — entertainment constants, not Blu-ray specs.
How it works
Speed (km/h) = 3600 ÷ seconds per kilometre. Distance = speed × movie duration in hours.
Assumes continuous running at even pace. Bathroom breaks, intermissions, and Ringwraiths are ignored.
Frequently asked questions
Are the runtimes exact?
No. They are rounded entertainment totals for popular film marathons. Swap titles if your cut differs.
Can I share the result?
Yes. Use Share Result to copy a link that recreates your movie and pace.
