Fasting Schedules

On level ground most bikes cruise at 15–30 km/h, while trained racers, track bikes, and steep descents can push bicycle speeds past 100 km/h.

At the Olympics, top triathletes finish the 1.5 km swim, 40 km bike, and 10 km run in about 1:45–1:55, with bike speeds near 40 km/h and run pace near 3:10

Recreational snowboarders often ride at 20–40 mph, while speed specialists on closed tracks can exceed 70 mph under controlled conditions.

Most recreational roller skates cruise around 6–12 mph, while trained speed skaters can push 20–30 mph or more on smooth ground.

Top sprinters cover the 100 metres in under 10 seconds, and current records hint that human limits sit somewhere around the mid-9 second range.

Most 9-year-olds jog a mile at roughly 4–7 mph, while short sprints can briefly hit 10–12 mph depending on fitness and practice.

A human hand can move from under 5 mph in daily tasks to around 100 mph in elite throws, with record punches near 45 mph.

Most amateur footballers run a 5K in 18–25 minutes, while top professionals often finish between 15 and 18 minutes.

To decide how long to fast, match your fasting window to your health, goal, and daily routine, and stay inside medically advised time limits.

Apple cider vinegar during intermittent fasting works best in small, diluted amounts that match your schedule, health history, and fasting style.
