Climbing one flight of stairs burns roughly five to ten calories, so 100 flights can torch 500 to 1,000 calories while challenging your lungs, legs, and heart.
Why people chase 100 flights
Many see 100 flights as a measurable badge of fitness, a way to test endurance, build lower-body strength, and compress a long cardio session into a steep vertical journey.
Because stair climbing spikes your heart rate quickly, it feels like a shortcut to the sweaty, breath-burning zone that many equate with an effective workout.
What your body is actually doing
At a vigorous pace, each step drives you upward, demanding power from your quads, glutes, and calves while your cardiovascular system works hard to deliver oxygen.
The repeated concentric pushes and controlled descents create a demanding interval style stimulus that can improve stamina, but also increase impact stress on joints and tendons.
Comparing 100 flights to other workouts
In terms of time, 100 flights might take twenty to forty minutes depending on pace and recovery, similar to a long run or a circuit of weighted step-ups in terms of effort, but far more joint friendly than pounding concrete for hours.
Conclusion: Is it worth it
If you are healthy, gradually build up to 100 flights of stairs a good workout, mix in walking breaks, use proper shoes, and respect warning signs, this vertical challenge can be a powerful, time efficient addition to your routine while remaining one demanding flight at a time.
