You can ballpark it using typical stair-climb speeds and some reasonable assumptions.

Quick Scoop

For most reasonably fit adults, climbing 110 flights of stairs without long breaks would likely take around 25–45 minutes , depending heavily on fitness, pace, and whether you stop to rest.

Step 1: Turn flights into time

We need two estimates:

  1. How many steps is 110 flights?
    • A common average is about 15 steps per flight , though real buildings vary.
 * 110 flights × 15 steps ≈ **1,650 steps total**.
  1. How long per step or per flight?
    • Health and fitness tests often use short stair bursts; for example, one protocol times people on 20 stairs (about 2 flights) in 6–17 seconds for healthy adults going quickly but not running.
 * Another heart-health test suggests **4 flights (about 60 steps) in under a minute** as a “good” effort, which is roughly **1 step per second** at a strong but sustainable pace.

If you extend that pace to a longer, steady climb (and slow it slightly so it’s sustainable):

  • At 1 step per second (strong, athletic pace):
    • 1,650 steps ≈ 27–30 minutes , allowing for a few brief pauses.
  • At 0.7 steps per second (moderate, still continuous):
    • 1,650 steps ≈ 40 minutes.

What it feels like at different fitness levels

These are rough, story-style scenarios, not strict rules:

  • Highly fit / used to stairs or hiking
    • Might climb close to 1 step per second with short pauses every 10–20 flights.
    • Total: about 20–30 minutes if they push, maybe 30–35 minutes at a calmer pace.
  • Average, somewhat active adult
    • Likely to start fast, then slow and insert short breaks.
    • Realistic total: 30–45 minutes , often with “mini-rests” every few flights.
  • Deconditioned or with heart/lung issues
    • Needs frequent breaks and a much slower cadence.
    • Could easily stretch past 45–60+ minutes , and may not be safe without medical clearance, especially at high rise heights.

Safety and practical tips

Because 110 flights is a lot, treat it like a serious workout, not a casual stroll:

  • Watch your heart and breathing. If 4 flights leave you gasping or dizzy, that’s a red flag; a heart-health study specifically uses 4 flights as a screening test.
  • Break it into chunks. For instance, 10–15 flights, rest 1–2 minutes, repeat.
  • Hydrate and cool down. Long stair sessions can be surprisingly intense; stair climbing for even 15–25 minutes is often recommended as a solid daily workout.

A simple rule of thumb

If you just want a quick mental shortcut:

  • Estimate 15 steps per flight ,
  • Assume 1,500–1,700 steps total ,
  • Pick a pace between 0.7–1.0 steps per second ,
  • Expect 25–45 minutes plus rest, depending on how fit you are and how hard you push.
