Adventure Travel Checklist: What to Pack for a Week-Long Ultra Run

Ever tried to cram a week‑long ultra into a backpack that feels like a sack of rocks? The difference between a triumphant finish line photo and a night spent nursing a blister is often what you left behind. Below is the exact list that got me through the 100‑mile “Desert Loop” without sacrificing my sanity—or my camera lenses.

Footwear: The Foundation of Every Mile

Trail Shoes vs. Racing Flats

Most runners think “the lighter, the better.” For a multi‑day effort that’s a recipe for disaster. Trail shoes give you protection, grip, and a bit of cushioning that keeps your feet from feeling like a broken drum. Racing flats are great for a single 30‑k race, but on a week‑long grind they’ll wear out faster than a cheap pair of socks.

My Go‑To Pair

I run the Salomon S/Lab Sense 8 for the first 50 miles, then switch to a more durable pair of Altra Lone Peaks for the back half. The switch saves the soles and gives my calves a fresh angle. Pack a spare pair of insoles—gel inserts for the downhill and a firmer foam for the climbs.

Socks, Socks, Socks

Never underestimate the power of a good sock. Merino wool blends are my favorite because they wick sweat, resist odor, and stay warm when the night temperature drops below freezing. Pack at least three pairs and rotate them daily.

Clothing Layers: Stay Warm, Stay Cool

Base Layer

A lightweight, moisture‑wicking shirt (think polyester or merino) is non‑negotiable. Cotton traps sweat and turns you into a walking soggy sandwich.

Mid Layer

For a week‑long run you’ll encounter sun‑soaked mornings and sudden alpine chills. A thin fleece or a soft‑shell jacket that packs into its own pocket is perfect. I keep a Patagonia Nano‑Air 2.0 in my pack; it’s barely there until you need it.

Outer Shell

A breathable, waterproof shell protects you from rain, wind, and the occasional dust storm. Look for a “vented” design with pit zips so you can let excess heat escape without opening the whole jacket.

Bottoms

One pair of quick‑dry shorts for hot days, one pair of lightweight trail pants with zip‑off legs for cooler evenings, and a pair of insulated leggings for high‑altitude nights. All should have a built‑in gaiter or be compatible with gaiter clips to keep debris out of your shoes.

Nutrition & Hydration: Fuel for the Long Haul

Calorie Counting on the Trail

An ultra runner burns roughly 6,000–8,000 calories per day. That’s a lot of fuel, and it can’t all be in the form of gels. I rely on a mix of real food and performance products.

Solid Food: Dehydrated meals (like Mountain House or Backpacker’s Pantry) are lightweight and easy to rehydrate. I also bring a small stash of peanut butter packets, jerky, and a few granola bars for quick bites.
Liquid Calories: A 2‑liter hydration bladder plus a couple of water bottles give you about 3 liters of fluid. Add a few electrolyte tablets or a pinch of sea salt to keep sodium levels up.
Gels & Chews: I keep a handful of GU Energy Gels and Clif Bloks for the steep climbs when you need a quick surge. Don’t over‑rely on them; they’re a supplement, not a staple.

Packing Strategy

Divide your food into daily “pouches” that you can grab without rummaging through the whole bag. Use zip‑lock bags labeled “Day 1,” “Day 2,” etc. This saves time and prevents you from accidentally eating tomorrow’s lunch today.

Tech & Navigation

GPS Watch

A reliable GPS watch (Garmin Fenix 7 or Suunto 9) tracks distance, elevation, heart rate, and even offers breadcrumb navigation. Set up a “course” before you leave and enable “auto‑pause” for those inevitable rest stops.

Maps & Compass

Don’t trust a single device. Carry a printed topographic map of the route and a lightweight compass. In the rare event your watch dies, you’ll still know which way is north.

Phone & Power

A rugged phone case and a solar charger (like the Goal Zero Nomad 7) keep your communication line open. I also stash a small power bank (10,000 mAh) for emergencies. Remember, a phone is a tool, not a lifeline—don’t let it distract you from the trail.

Safety & First Aid

Basic Kit

Blister Kit: Moleskin, adhesive bandages, and a small pair of scissors.
Pain Relief: Ibuprofen or naproxen for aches, plus a few tubes of anti‑inflammatory gel.
Antibiotic Ointment: For any cuts that might get dirty.
Emergency Blanket: Lightweight, reflective, and can double as a ground sheet.

Personal Medications

If you have any prescription meds (asthma inhaler, allergy epi‑pen, etc.), pack them in a waterproof pouch and keep them easily accessible.

Emergency Contact Card

Write down your emergency contacts, the race’s base camp phone number, and your GPS coordinates on a small card. Slip it into your running vest pocket.

Optional Extras That Might Save Your Day

Gaiters: Keep rocks, mud, and snow out of your shoes. I use a pair of Black Diamond FrontPoint Gaiters for the high‑altitude sections.
Headlamp: Even if you plan to finish before dark, a bright headlamp (100 lumens or more) is a lifesaver for early starts or unexpected weather.
Camera Gear: A compact mirrorless camera (Sony a6400) and a spare battery. I love capturing sunrise over the ridge, but keep the gear in a dry bag.
Portable Seat Pad: For those inevitable “just sit and eat” moments on a rocky outcrop.
Multi‑Tool: A small Leatherman with a knife, scissors, and a bottle opener—because you never know when you’ll need to cut a zip‑tie or open a snack pack.

Packing It All Together

Backpack Choice: A 45‑50 liter trail pack with a dedicated hydration sleeve and external attachment points. The Osprey Atmos AG 50 works great for me; the anti‑gravity suspension distributes weight evenly.
Weight Distribution: Heavy items (food, water, gear) go close to your spine and centered low. Lighter items (jacket, camera) sit higher and toward the back.
Compression: Use the pack’s compression straps to keep the load tight. A loose pack wastes energy and can cause chafing.
Test Run: Do a short 10‑mile run with the fully packed bag. Adjust straps, add or remove items, and note any discomfort before you hit the trail.

Packing for a week‑long ultra is a balancing act between “I might need this” and “I’ll survive without it.” Stick to the essentials, respect the weight, and trust the gear you’ve tested. The trail will reward you with unforgettable vistas, a sense of accomplishment, and maybe a few new scars to tell stories about.
