Death by 10 meter
With a continuously running clock run 10 meters the first minute, run 20 meters the 2nd minute, 30 meters at the 3rd minute…. continue until you cannot complete the distance within the minute.
Every 10 meters touch the ground and change directions. Whatever time is remaining before the next minute is your rest.
