Available for Life, Forward, Endure, Advanced, and Stirling

Stair Conditioning

This Challenge must be completed three times on three separate days, within the 12-week training cycle. Completion on fewer than three days does not meet the requirement.

We recommend spacing your efforts once per week over a three-week period. This cadence supports better adaptation and consistent conditioning over time.

Challenge Purpose

• Physical Conditioning
  Climbing stairs under load builds full-body strength, trains your stabilizing muscles, and improves power and cardiovascular endurance, all of which support performance in longer endurance events and high-output movements.

• Mental Conditioning
  Extended stair climb efforts demand pacing, grit, and presence. This Challenge prepares you for the kind of sustained discomfort you’ll face in both standalone stair climb events and multi-hour evolutions during endurance events.

Challenge Parameters

The Firefighter Challenge must be completed using consecutive flights of stationary stairs or an approved gym stair-climbing machine. A weighted ruck must be worn for the entire duration. (See Challenge Weight Requirements below.)

Acceptable Stair Options

• Outdoor public stairs (city centers, monuments, etc.)

• Park or playground stairs

• Bleacher or stadium stairs

• Parking garage stairwells

• Multi-story building stairwells

Stairs must be climbed in both up and down directions.

Exception: Stair climbing machines (e.g., StairMaster) are acceptable substitutes and are recommended for athletes managing joint concerns (e.g., arthritis, past knee or ankle injuries). These machines simulate only the upward portion of stair climbing.

Completion Criteria

To complete the Challenge, the following standards must be met:

Duration (Per Attempt):

• Life: 15 minutes

• Forward: 30 minutes

• Endure: 45 minutes

• Advanced: 60 minutes

• Stirling: 60 minutes

Each session must be uninterrupted and executed in one continuous effort.

Frequency:

• Complete the full-duration effort three separate times during the 12-week Class.

• Efforts must be spaced no less than 7 days apart (i.e., once per week minimum).

• All three efforts must meet your program’s duration standard to qualify.

Challenge Weight Requirements

• Life, Forward, Endure: No stated minimum weight, but a ruck with a challenging load must be worn at all times.

• Advanced:

  • 45 lb (dry weight) if you weigh 150 lb or more

  • 30 lb (dry weight) if you weigh under 150 lb

• Stirling:

  • 50 lb (dry weight) for all rosters

• Compete: This Challenge is not currently part of PATHFINDER Compete.

Pacing Tips

Stair work hits differently. It’s easy to go out too hard and burn out early. Treat this like a long ruck, not a sprint.

Start slower than you think you need to.
If you’re doing this outside, find a pace you can sustain for 5+ minutes without resting. If it feels too easy at first, you’re doing it right.

Build a rhythm.
Use the rail for stability if needed, but focus on smooth, continuous movement. Count steps. Use the corners of the stairwell as a breathing checkpoint. Keep your body tall, core braced, and feet fully landing on each step. Don’t bounce.

Avoid "dead stops."
If you need to catch your breath, slow to a step-by-step pace instead of standing still. This keeps your momentum alive and your legs in motion.

Train your descent.
Downstairs is where your legs will start to whine. Quads, glutes, and knees take the hit, especially under load. Take shorter, deliberate steps. Keep your foot placement quiet and stable to reduce impact over time.

If you’re using a machine:
Set a sustainable step rate and hold it. Resist the temptation to touch the rails for the full time. Your ruck should be doing the work, not the handlebars.

Mental Strategies

This Challenge is simple, but it’s not easy. You’ll hit the mental wall faster than the physical one, especially in weeks two and three. That’s where the work is.

Break it into blocks.
Don’t think about “60 minutes.” Think about 5-minute chunks. One song. One flight up. One descent. Reset your focus and go again.

Make a deal with yourself.
“I’ll reassess after the next 3 minutes.” Then go another 3. Keep moving. Make small promises and keep them. It adds up.

Remember why you’re here.
This is the kind of work that builds staying power, on the stairs, in an Event, and in real life. Nobody stumbles into stair endurance. You earn it. 

Qualifying Mileage

Mileage from this Challenge may be counted toward your program’s total mileage requirement. However, GPS tracking is often unreliable in enclosed spaces like stairwells and garages due to interference from concrete and steel.

To calculate mileage manually:

1. Count your total steps climbed.

2. Multiply the number of steps by 17 inches (the standard rise and tread of a stair) to get the total inches climbed.

3. Convert inches to miles:
   One mile = 63,360 inches (5,280 feet × 12 inches).
   So, to climb a full mile: 3,727 steps (63,360 ÷ 17).

Example:
Climb 1,000 steps >> 17,000 inches = 0.27 miles.
