Countdown
August
Two full days and nights of running the same 3.6 km loop. This is the long one: you run, sleep or rest when you choose, and keep adding laps.
Key facts
01Only full laps count, so a part lap at the end does not score
02Part of the loop is unlit at night, so bring your own light
03You can start later than the gun if you need to
