Power Hiking for Ultras: A Guide
Power Hiking for Ultras: A Training Guide¶
You trained for months. You nailed your long runs, dialed your nutrition, and showed up to your first 50-miler feeling ready. Then mile 26 hit a 2,000-foot climb and you tried to run it. By mile 35 your quads were shredded, your pace had cratered, and you spent the last 15 miles in a survival shuffle that turned a 12-hour goal into a 15-hour slog.
The runner who passed you on that climb? They were walking. Fast, deliberate, arms pumping, poles clicking. They looked fresh. They finished two hours ahead of you.
That is the difference power hiking makes.
Power hiking is the deliberate, trained skill of walking fast on steep and technical terrain. It is not giving up. It is not slowing down because you are tired. It is a calculated decision to use the most efficient locomotion for the gradient, and it is the single most undertrained skill in ultrarunning.
In this guide, you will learn:
- Why power hiking is often faster than running on steep grades
- The exact grade threshold where hiking beats running
- How to train your hiking speed so it becomes a weapon, not a fallback
- Form fundamentals that add 2-3 minutes per mile to your hiking pace
- How to build power hiking into a structured training plan
Why Hiking Beats Running on Steep Grades¶
Here is a fact that surprises most road runners: on grades above 15-20%, the fastest ultrarunners in the world are walking. Not because they are tired. Because it is faster.
The biomechanics are straightforward. Running requires a flight phase where both feet leave the ground. On steep terrain, that flight phase costs enormous energy for almost zero forward progress. You are bouncing up, not moving forward. Walking eliminates the flight phase entirely. Every step pushes you forward.
Research on uphill locomotion shows that the crossover point — where walking becomes more metabolically efficient than running — occurs around 15-20% gradient for most trained runners. Above that, running costs more oxygen per meter gained for the same or slower speed.
But the real advantage is not just efficiency on one climb. It is what power hiking does to the rest of your race. A runner who hikes the climbs arrives at the top with a heart rate 15-20 beats lower than the runner who ground it out. That means faster recovery on the descent, more energy for the flats, and legs that still work at mile 80 when everyone else is falling apart.
The math of ultramarathons is simple: the runner who slows down the least wins. Power hiking the climbs is how you slow down the least.
When to Hike vs. Run: A Decision Framework¶
The biggest mistake runners make is deciding to hike based on how they feel. By the time you feel like you need to hike, you have already burned matches you cannot get back. You need rules, not feelings.
Here is a framework you can use on race day:
Grade-Based Rules¶
- Below 10% grade: Run unless you are in the back half of a 100-miler and managing fatigue
- 10-15% grade: Run if the climb is short (under 5 minutes). Hike if it is longer
- Above 15% grade: Hike. Almost always. Even if you feel strong
- Above 25% grade: Power hike with poles if you have them. Running here is wasting energy
Heart Rate Rules¶
If you wear a heart rate monitor, use this as a secondary check:
- If your heart rate exceeds 85% of max on a climb, you are running too hard. Switch to hiking
- If your heart rate does not drop below 75% of max within 2 minutes of cresting a climb, you were pushing too hard on the ascent
Time-of-Race Rules¶
- First third of the race: Hike anything above 15%. Bank energy
- Middle third: Hike anything above 10%. Protect your legs
- Final third: Hike anything that feels hard. Ego is the enemy here
The best ultrarunners pre-study the course profile and decide before the race which sections they will hike. They do not make the decision in the moment. They have a plan.
How to Train Your Power Hiking Speed¶
Power hiking is a skill. Like any skill, it improves with deliberate practice. Most runners never train it, show up on race day, and hike at 25-30 minutes per mile when they could be hiking at 16-18 minutes per mile. That difference adds up to hours over a 100-mile race.
Here is how to build hiking-specific fitness:
Dedicated Hiking Workouts (2x per week during build phase)¶
Workout 1: Steep Hike Repeats
Find a hill with a 15-25% grade. Hike up as fast as you can for 5-10 minutes. Jog or walk down for recovery. Repeat 4-8 times. Focus on maintaining arm drive and a quick cadence. This is the power hiking equivalent of hill sprints.
Workout 2: Long Hike Endurance
On your long run day, choose a route with sustained climbing. Hike every climb above 10% grade at race-effort intensity. The goal is time on feet at hiking pace — building the muscular endurance in your calves, glutes, and hip flexors that power hiking demands.
Treadmill Option¶
Set the treadmill to 15% incline, 3.5-4.0 mph. Hold that for 20-30 minutes. It is brutal and boring, but it builds hiking-specific fitness faster than anything else. Increase speed by 0.1 mph each week.
Strength Work That Transfers¶
Power hiking loads your calves, glutes, and hip flexors differently than running. Add these to your strength routine:
- Calf raises (3x15, weighted): The calf is the engine of the power hike
- Step-ups (3x12 each leg, weighted): Mimics the hiking stride on steep terrain
- Hip flexor marches (3x20): Drives knee lift and cadence
- Glute bridges (3x15, single leg): Stabilizes your pelvis on uneven ground
Progressive Overload¶
Like running, hiking fitness builds through progressive overload. Start with 2,000-3,000 feet of dedicated hiking elevation per week. Build by 10-15% weekly until you reach 5,000-8,000 feet per week in your peak training block. This is on top of whatever elevation you gain while running.

Power Hiking Form: The Details That Matter¶
Good hiking form is the difference between an 18-minute mile and a 25-minute mile on the same grade. Small adjustments compound over hours.
Posture¶
Lean forward from your ankles, not your waist. Your torso should angle into the hill so your center of gravity stays over your feet. Bending at the waist loads your lower back and kills your hip extension.
Arm Drive¶
This is the single biggest form change most runners need. Pump your arms aggressively, elbows at roughly 90 degrees, hands driving forward and up. Your arms should be working as hard as your legs. On steep grades, push your hands against your thighs on each step for extra drive — this is called the "thigh push" technique and it adds measurable speed.
Cadence¶
Short, quick steps beat long strides on climbs. Aim for 50-60 steps per minute (count one foot). Long strides overextend your hip flexors and force your calves to work through a larger range of motion, which accelerates fatigue.
Foot Placement¶
Land on your midfoot or forefoot, not your heel. Heel striking on steep grades wastes energy because your foot has to roll through a longer ground contact before pushing off. Place your foot flat and push straight down.
Trekking Poles¶
Poles are not required, but on courses with extended climbing (10,000+ feet of gain), they distribute load to your upper body and can reduce quad fatigue by 20-30%. If you plan to use poles on race day, train with them. Pole technique is its own skill — practice the rhythm of plant-push-step until it is automatic.
Reading Your Hiking Data¶
One of the psychological barriers to power hiking is that your data looks "bad" afterward. You see a 22:00/mile split on Strava and your brain screams failure, even though that split was on a 20% grade where 22:00 is genuinely fast.
Context matters. Here is how to read your mixed run/hike data:
What Good Hiking Splits Look Like¶
| Grade | Good Hiking Pace | Elite Hiking Pace |
|---|---|---|
| 10-15% | 18-22 min/mile | 14-16 min/mile |
| 15-20% | 20-26 min/mile | 16-20 min/mile |
| 20-25% | 24-30 min/mile | 18-24 min/mile |
| 25%+ | 28-35 min/mile | 22-28 min/mile |
If your hiking splits fall in the "good" range for the grade, you are doing it right — regardless of what your overall average pace looks like.
Elevation vs. Pace¶
The metric that matters for hiking is vertical speed — feet gained per hour. A strong power hiker gains 1,500-2,000 feet per hour on moderate grades. Elite mountain runners hit 2,500-3,000 feet per hour. Track this number instead of pace and you will have a much better picture of your hiking fitness.
NavRun's analytics dashboard shows your elevation data alongside pace and heart rate, so you can see exactly how your climbing efforts break down across a run.
Race-Day Execution¶
Training the skill is half the battle. Executing it under race pressure is the other half.
Pre-Race: Study the Course Profile¶
Before race day, identify every climb on the course. Mark which ones you will hike and which you will run. Write it down. Share it with your crew if you have one. The decision is already made — you are just executing the plan.
Aid Station to Aid Station¶
Think in segments, not miles. "I will hike from aid station 3 to the top of the ridge, then run the descent to aid station 4." This approach breaks a 100-mile race into manageable pieces and gives you natural checkpoints.
The First Climb Test¶
Your first significant climb is a calibration opportunity. Hike it at what feels like a moderate effort and check your heart rate. If you are above 80% of max, slow down. You need that heart rate data from the first climb to set your effort ceiling for the rest of the race.
When Others Are Running, Let Them¶
This is the hardest part. At mile 10, you will watch other runners charge up a climb while you hike. Your ego will scream at you to run. Do not listen. Those runners will be walking — not power hiking, just walking — at mile 60. You will be the one passing them.
Common Questions About Power Hiking¶
Q: Will power hiking make me slower overall?¶
No. In most ultras with significant elevation gain, a run/hike strategy produces faster finish times than trying to run everything. You lose a few minutes on the climbs and gain far more on the descents and late-race flats because your legs are not destroyed.
Q: At what distance does power hiking become important?¶
Power hiking matters for any trail race with significant climbing — even a hilly 50K. It becomes critical for 50-milers and essential for 100-mile races. The longer the race, the more the energy savings compound.
Q: Should I use trekking poles?¶
If your race has more than 10,000 feet of elevation gain, poles are worth considering. They reduce quad load, improve stability on technical terrain, and give you something to do with your arms on long climbs. But train with them first — poles you have never used are poles that slow you down.
Q: How fast should I be able to power hike?¶
A good target for a trained ultrarunner is 15-18 minutes per mile on a 15% grade. If you are above 22 minutes per mile on moderate grades, you have room to improve and dedicated hiking training will help significantly.
Q: Can I train power hiking on a treadmill?¶
Yes, and it is one of the most effective ways to build hiking-specific fitness. Set the incline to 15% and walk at 3.5-4.0 mph. It is not exciting, but 20-30 minutes twice a week will transform your hiking speed within 6-8 weeks.
Q: How do I transition smoothly between running and hiking?¶
Practice the transition in training. Many runners lose 10-15 seconds every time they switch from running to hiking because the gear change feels awkward. The key is to start your arm drive before your legs fully transition. Arms lead, legs follow.
