Key Takeaways

  • Build up your trail running fitness and test gear on overnight trips before embarking on a fastpacking adventure. Start slow on familiar routes.
  • Pack light – under 15 lbs (6.8 kg) – with versatile essentials like a running vest/pack, moisture-wicking clothes, trekking poles, water filtration, and an ultralight sleep system.
  • Master efficient fastpacking techniques like quick foot strikes, power hiking uphills, shorter strides downhill, and using your arms for stability on descents.

What is Fastpacking?

Fastpacking is an exciting fusion of trail running and ultralight backpacking. It traces its roots to the 1990s ultralight movement, enabling adventurers to cover more ground quickly with speed and endurance.

Fastpackers typically aim to keep their backpack weight under 15 pounds (6.8 kg), sometimes even less than 10 pounds (4.5 kg). Fastpacking can be undertaken unsupported, self-supported, or supported, offering various challenges.

Getting Started with Fastpacking

Here’s how you can begin your first adventure:

  1. Build Your Fitness: Fastpacking is more enjoyable when you’re physically prepared. Start by getting comfortable with trail running without a backpack. Challenge yourself with long runs over rough terrain and consecutive hiking or running days to get used to being on your feet.
  2. Dial in Your Gear: You’ll be running with a loaded pack, so pick gear that works for you. Get to know your stuff before your first trip. Do a test overnight camping trip to make sure your gear is good and practice hiking and running with the backpack you’ll use. Ultralight gear costs a lot. But you don’t need to buy it all at once. Start with some must-have items.
  3. Partner Up or Seek Advice: New to fastpacking? Team up with someone who has experience. They can keep you safe and give tips. Don’t have a partner? Look online for hiking or trail running groups. Ask them for advice. Facebook is an easy way to find groups.
  4. Start Humble: Begin your fastpacking journey by running your favorite local routes with the same weight and backpack you intend to use. This helps you address any gear issues close to home. For your first experience, stick to familiar terrain or well-traveled routes.
  5. Be Realistic About Pace: Carrying gear on the trail will slow you down at first. Be realistic about your pace. A good average pace is around 14-15 minutes per mile. But this depends a lot on the terrain and is hard to estimate.

Fastpacking Techniques

Learning efficient fastpacking techniques will make your time on the trail more enjoyable and help you cover more ground. Here are some tips:

  • Use a light, quick foot strike when running. Land on your mid-foot instead of heel striking.
  • Walk uphills and run the flats and downhills. Use trekking poles for stability.
  • Take shorter, quicker strides down steep trails. Avoid overstriding.
  • Keep your arms low and bent at 90 degrees when descending. Avoid tight upper body tension.
  • Lean forward slightly and keep your eyes ahead when going uphill. Stay upright when descending.
  • Take breaks to walk when you start feeling fatigued. Don’t push through pain.
  • Power hike uphills by engaging your glutes, calves and arms. Keep your steps short and torso upright.

Practice these techniques during your training runs before your trip. They will become second nature quickly. Efficient movement makes fastpacking sustainable over long distances.

What to Take Fastpacking?

For fastpacking, pack light with essentials only. Prioritize lightweight and versatile gear. Here’s what to bring:

  1. Backpack: Your backpack is crucial; it should fit you well and allow for efficient gear storage. Some prefer hydration vests or running backpacks, while others find daypacks suitable. Test your chosen pack to ensure comfort when loaded.
  2. Clothing: Opt for lightweight, moisture-wicking performance clothing that keeps you comfortable while running. A waterproof and packable jacket, extra socks, shirt, and shorts are essential. Additionally, carry a lightweight insulated jacket for colder weather or higher altitudes.
  3. Trekking Poles: If you intend to use trekking poles, make sure to practice running with them before embarking on your adventure. Trekking poles not only enhance load stability and balance, especially on downhill stretches but can also serve a dual purpose as part of your shelter setup.
  4. Water: Know where reliable water sources are along your route and carry the necessary water filtration system. Options include squeeze-style filters, filter bottles, chemical treatments, and straw filters. Don’t forget electrolytes.
  5. Food: Choose easy-to-digest trail foods like energy bars and gels since you’ll likely crave carbs while fastpacking. But keep in mind you can only digest about 3 ounces (80 g) of carbs per hour. Eating more may cause stomach issues. For larger meals, some fastpackers go stoveless and eat no-cook foods to save weight.
  6. Shelter: Your choice of shelter depends on factors like weather conditions and personal preferences. Minimalists might prefer an ultralight tarp or a simple bivy, while others may opt for a full-coverage ultralight tent.
  7. Sleep System: Consider a backpacking quilt instead of a traditional mummy sleeping bag to reduce weight. Quilts are designed to be used atop a sleeping pad and weigh less due to the absence of hoods, bottom insulation, or zippers.

How to Plan a Fastpacking Trip?

So, you’re eager to set off on your adventure, but where to begin?

  1. Research Routes: Ask experienced fastpackers for trail recommendations and connect with online fastpacking communities. Facebook groups are a great resource. Chances are, someone has already done the route you’re planning, so tap into that experience. You can also check the popular route options listed here.
  2. Choose a Suitable Route: Choose a route that matches your fitness level and skills. If you’re new to fastpacking, pick familiar terrain to build confidence. Plan daily mileage based on how many hours you can run, considering elevation changes. Routes with the most descending are toughest on your body.
  3. Water Sources: Know where reliable water sources are along your chosen route and how far apart they are. We suggest to check topographical maps.
  4. Weather Forecast: Given that you will rely on minimal gear, checking the forecast is crucial. While you don’t have to prepare for the worst-case scenario, knowing the expected weather conditions will help you pack appropriately.
  5. Permits: Research whether backcountry permits are required for your chosen route. Contact the relevant agency for permit details and any restrictions.


As you lace up your shoes and venture into this world of running with a light pack through majestic mountains, remember that fastpacking is not just about covering ground but also about the exploration itself. It’s about pushing your limits, finding solace in nature, and discovering the incredible freedom of self-reliance.

Make your first steps into fastpacking and let each stride take you deeper into nature on exciting multi-day adventures. But don’t forget safety. If this is your first trip, it’s okay to have some fears. Start small, pack well, and work your way up at a comfortable pace.


What to bring fastpacking?

When fastpacking, it’s essential to pack light yet efficiently. Prioritize lightweight and versatile gear, including a well-fitting backpack, moisture-wicking performance clothing, trekking poles for stability, and a water filtration system. Be patient with gear selection, start with the essentials, and gradually build up your fastpacking kit. Don’t forget easily digestible trail foods like energy bars and a suitable shelter, depending on weather conditions and preferences. Consider a backpacking quilt for a lightweight sleep system. These essentials will help you embark on your fastpacking adventure with confidence and comfort.

What size pack for fastpacking?

Selecting the right pack size for fastpacking is crucial. The ideal pack size often depends on personal preference and the duration of your adventure. Many fastpackers opt for packs ranging from 12 to 30 liters in capacity. A 12-liter pack suits those who prioritize minimalism and lightweight gear, while a 30-liter pack offers more space for additional comfort items or longer trips. It’s essential to strike a balance between carrying your essentials and maintaining agility, so choose a size that fits your needs and keeps you moving swiftly through the wilderness.

How should I train for my first fastpacking trip?

Start by getting comfortable trail running long distances without a pack. Work your way up to trail runs of 10+ miles. Do some overnight shakedown hikes with your fastpacking gear to get used to weight on your back. As you get closer to your trip, do some trail runs wearing your fastpacking pack loaded up. Start small (5-10 lbs) and increase the weight. Get in the habit of running uphills and hiking downhills. Mix up hill training and lift weights to build leg strength. Work on hiking efficiently with trekking poles. The goal is to prep your body for the unique demands of fastpacking.

What are some fastpacking gear essentials?

Some basic fastpacking gear essentials include: Lightweight backpack (25 liters or less), Performance clothing that wicks moisture, Trekking poles, Water filtration/treatment system, Compact first aid kit, Navigation (map, compass, GPS device), Lightweight shelter (tarp, bivy, tent), Sleeping quilt and sleep pad, Headlamp and pocket knife. You’ll likely also want ultralight cooking gear, bear canister if required, and camera gear.

What are some fastpacking techniques?

Some helpful fastpacking techniques include: Using trekking poles for efficiency, shorter/quicker strides downhill, leaning forward uphill and staying upright downhill, power hiking uphills by engaging glutes/arms/calves. Also, take walk breaks when fatigued, keep arms bent when descending, land midfoot when running, and keep your pack weight as low as possible.

How long do most fastpacking trips last?

Most fastpacking adventures range from 2-5 days depending on the route and your experience level. Beginners should start with easier 2-3 day trips before progressing to longer expeditions. Experienced fastpackers tackle week-long thru-hikes covering over 150 miles. But any distance that challenges your abilities can be rewarding.

Where can I find others to fastpack with?

Look for fastpacking groups on Facebook to connect with others in your area. Check outdoor clubs and gear shops for trips or partners. Use apps like Strava to find and follow other fastpackers nearby. Consider joining a guided fastpacking trip to learn techniques. The community is welcoming to newcomers seeking advice.
