Beginner's guide

So you're getting into ultrarunning

Anything longer than a marathon counts, and 50k is the usual first step. The gear is a different stack from trail running: a real vest, a headlamp that lasts all night, poles, and a fueling plan. Here is what to buy, and what to skip.

The 60-second version

If you only buy 3 things to start:

  1. ADV Skin 12 Set — Salomon ADV Skin 12: the vest most ultra runners start in. Stable, bounce-free, and holds a full race kit.
  2. ACTIK CORE — Petzl Actik Core: bright, rechargeable, and long-lasting enough for a night section.
  3. Endurance Fuel (Berry, 30 servings) — Tailwind Endurance Fuel: calories and sodium in one bottle, so fueling stays simple past mile 30.

Before you buy anything

A few things worth knowing first

Run a 50k before you buy a vest for a 100 miler. Your first ultra is long enough to teach you what you actually carry. Buy an 8-12 liter vest, load it on training runs, and only then decide whether you want smaller or bigger.

Check the race's mandatory gear list before you spend. Most ultras require a headlamp, a waterproof shell, an emergency blanket, a whistle, and a cup. A vest with room for that list matters more than the brand.

Use the trail shoes you already trust. The best ultra shoe is the one that has not blistered you on a three-hour run. Do not debut new shoes, socks, or a vest on race day.

The gear

What you actually need

Running Vests

A vest replaces the handheld bottle once you pass about two hours. Look for soft flasks on the chest (easy to reach and refill), a snug fit that does not bounce, and 8-12 liters of room for the mandatory kit. Try one on loaded with water. A vest that rubs at mile 5 will wreck mile 30. Size by chest measurement, not by how you wear a t-shirt.

Best starter
Salomon

ADV Skin 12 Set

$$$

Our rating

The Skin 12 is the vest you will see in the start corral at most ultras. Stretchy mesh panels hold it close to the body, the two 500 ml soft flasks sit on the chest where you can drink without breaking stride, and there is room for a shell, headlamp, and food. Flasks are included. Price moves with size and color: about $105 on this listing, up to about $170.

What we like

  • Two soft flasks included, no extra purchase
  • Stretch mesh fit stays put at ultra pace
  • 12 liters holds a full mandatory kit

What to know

  • Runs snug, and sizing is unforgiving
  • Flasks can leak if the caps are not seated
Specialty pick
Ultimate Direction

Race Vest 6L

$$$

Our rating

This is the minimalist option for runners who race with aid stations every 8-10 miles. It weighs about 6 oz, has a lot of easy-reach pockets, and comes with two soft flasks. Buy it second, once you know your race kit and how little you can carry.

What we like

  • Very light at about 6 oz
  • Soft flasks included
  • Nine exterior pockets for fast access

What to know

  • Too small for remote races with big gear lists
  • Smaller capacity means careful packing

Headlamps

Most 100k and longer ultras involve running in the dark, and many 50ks start before sunrise. You want a lamp that runs six or more hours on a medium setting, sits stable on your head without bouncing, and is bright enough to read trail at running speed. Carry a spare set of batteries or a backup light. Rechargeable lamps are great until you forget to charge them.

ACTIK CORE Best starter
Petzl

ACTIK CORE

$89.00 as of Jun 22, 2026

Our rating · Only 3 left in stock - order soon.

The Actik Core pairs a rechargeable CORE battery with the option of three AAAs as a backup. It is bright enough to run on technical trail, has a red light for aid stations, and a comfortable headband that doesn't slip. Around $80.

What we like

  • Rechargeable, with AAA backup in an emergency
  • Red light mode for aid stations and crew
  • Comfortable band stays put on a run

What to know

  • Heavier than race-day headlamps
  • High mode drains the battery fast
Spot 400 Budget pick
Black Diamond

Spot 400

$$

Our rating

The Spot 400 is a proven, simple headlamp at about $70 that takes AAA batteries (and a rechargeable pack as an optional extra). It is rated waterproof and dimmable, with a red night-vision mode. Plenty for a first 50k.

What we like

  • Cheaper than most trail-ready headlamps
  • Waterproof and dimmable
  • Easy to swap batteries during a race

What to know

  • Less bright than rechargeable 600-lumen lamps
  • Needs spare AAAs for long nights
Upgrade pick
Petzl

SWIFT RL

$$

Our rating

The Swift RL adjusts its beam automatically to the terrain, which extends battery life and means fewer button presses with cold fingers. It is a favorite of runners who do all-night ultras. Wait to buy until you know how long you'll spend in the dark.

What we like

  • Reactive lighting adjusts brightness automatically
  • Very bright for technical night trail
  • Rechargeable and light

What to know

  • Expensive compared with a basic headlamp
  • More features than a daylight racer needs

Trekking Poles

Poles save your legs on long climbs, and they are allowed (and common) in most mountain ultras. They are not for flat or fast courses, and a few races ban them. Learn to use them on training climbs first. Folding poles pack small enough to stash on your vest, and most runners prefer them to telescoping shafts. Check your race's rules before you buy.

Best starter
Cascade Mountain Tech

Carbon Fiber Folding Trekking Poles

$$

Our rating

A budget-friendly set of folding carbon poles that gives you the benefit of poles without a $195 commitment. They fold to about 17 inches, include a carry case, and lock with quick-lock tabs. A good first pair to learn pole technique.

What we like

  • Lower price than premium carbon poles
  • Folds small to stash in a vest
  • Carbon shaft cuts weight on long climbs

What to know

  • Quick locks can slip if set loose
  • Heavier than premium ultra poles
Upgrade pick
Black Diamond

Distance Carbon Z

$$$

Our rating

The pole most ultrarunners end up carrying. Three-section Z-fold design snaps together in a second, weighs under 6 oz per pole, and stows against your vest. Fixed length, so measure first: the common range is 110-130 cm.

What we like

  • Z-fold deploys in a second
  • Ultralight carbon shaft
  • Stows easily on a vest

What to know

  • Expensive for a first pair
  • Fixed length: no fixing a wrong size

Fuel and Electrolytes

Past marathon distance, the usual cause of a bad day is fueling, not fitness. Aim for roughly 200-300 calories an hour, and drink with sodium. Drink mix is the simplest way to start: one bottle gives you calories and electrolytes, and your stomach tolerates it better than gels late in a race. Test everything in training. Never try a new product at mile 40.

Best starter
Tailwind Nutrition

Endurance Fuel (Berry, 30 servings)

$$

Our rating

Tailwind is the drink mix most ultra runners start with: it packs carbs and sodium into one flavor and a simple rule. A scoop per flask, sip every few minutes. A 30-serving bag runs about $30.

What we like

  • Calories and electrolytes in one scoop
  • Easy on the stomach
  • Vegan, gluten free

What to know

  • Sweet flavors get tiring over hours
  • Lighter on calories per hour than gels alone
Specialty pick
SaltStick

Caps

$

Our rating

Salt capsules for hot days or heavy sweaters. Each capsule has about 215 mg of sodium plus potassium, calcium and magnesium. Take one every 30-60 minutes when it's hot. A bottle of 100 is about $25.

What we like

  • Targeted sodium for hot-weather races
  • Small and easy to carry in a pocket
  • A bottle lasts many long runs

What to know

  • Easy to overdo if you also use salty drink mix
  • Pill swallowing mid-run takes practice

Chafe and Blister Care

Skin problems end more ultras than muscle problems. Hours of repetitive friction raise blisters and chafe in places you never noticed on a 10k. Apply anti-chafe balm to every place that rubs (thighs, underarms, pack-strap contact, feet) before the start and again at aid stations. Tape any hot spot as soon as you feel it, not once it's a blister.

Best starter
Squirrel's Nut Butter

Anti-Chafe Stick

$

Our rating

An ultrarunning favorite: coconut oil, cocoa butter, beeswax. It stays on through hours of sweat. A 1.7 oz stick runs about $15 and goes on cleanly without getting your hands greasy.

What we like

  • Stays on through hours of sweat
  • Natural ingredients
  • Stick applicator keeps hands clean

What to know

  • Can melt in a hot pack
  • Costs more than basic balm
Budget pick
Body Glide

Original Anti-Chafe Balm

$

Our rating

A cheap, widely sold balm that works for most runners. Dry, invisible barrier that does not stain clothing. Under $10, and a good first thing to try.

What we like

  • Cheap and easy to find
  • No greasy residue
  • Water and sweat resistant

What to know

  • Wears off over very long distances
  • Can be slightly sticky in heat
P Sports Tape Specialty pick
Leukotape

P Sports Tape

$

Our rating

The tape ultrarunners use to prevent blisters on known hot spots. Rigid, strong adhesive, and stays stuck through sweat and stream crossings. Apply it before the race on spots that blister, and keep a few strips in your vest. A roll is about $13.

What we like

  • Sticks through sweat and water
  • Prevents blisters on hot spots
  • One roll lasts many races

What to know

  • Hard to remove
  • Needs pre-cutting before the race

Your first 12 weeks of ultrarunning

Going from a marathon, or even a 10k, to a 50k is mostly about patience, fueling, and time on your feet. Here is what the first twelve weeks look like, and what to ignore.

An ultramarathon is anything longer than 26.2 miles, and the usual first one is a 50k (about 31 miles). The surprise for most beginners is that it isn’t a faster, harder marathon. It is a slow, long day outdoors where eating, drinking, and staying calm matter as much as fitness.

This is what the first twelve weeks look like if you can already run about 3-5 miles comfortably.

Weeks 1–4: Build time on your feet

Stop thinking in pace and start thinking in hours. Run most days at an easy, conversational effort, and add one long run each weekend. Start the long run at 90 minutes and add 10-15 minutes per week.

Walk the hills. Every ultra runner does. Power-hiking a steep climb costs far less energy than running it, and you will be doing a lot of it on race day. Practice it now.

Skip speed work. At this stage, easy miles do more for you than intervals.

Weeks 5–8: Add the vest and fueling

Start carrying your vest on every long run, loaded the way you will on race day: two flasks, a shell, a headlamp, and food. Notice where it rubs and adjust the straps.

Now practice fueling. Aim for 200-300 calories an hour, starting in the first 45 minutes, before you feel hungry. Drink mix is the easiest place to begin, then add real food like pretzels, potatoes, or sandwiches. Your stomach is trainable, so test everything on long runs.

Try one back-to-back weekend: a long run on Saturday and a moderate one on Sunday. It teaches your legs to run tired, which is what the second half of an ultra feels like.

Weeks 9–11: Peak, then test your kit

Do your longest run, 4-5 hours, about three weeks before the race. Use it as a full dress rehearsal: same shoes, socks, vest, food, and anti-chafe balm. If anything rubs or upsets your stomach, you have time to fix it.

Run one session in the dark with your headlamp so race-morning starts aren’t a surprise. If your race allows poles and has big climbs, use them on a training climb or two.

Week 12: Taper and plan

Cut your mileage by about half and keep a few short, easy runs. You will feel restless and a little sluggish, which is normal. Lay out your gear, read the course profile, and write down when you plan to eat and drink.

On race day, go out slower than feels right. Most beginners who struggle in an ultra started too fast. Walk the hills, eat early and often, and treat aid stations as a pause, not a rest.

What to ignore

  • Fast pacing. Nobody holds a marathon pace for 31 miles. Slow is the plan.
  • Fancy gear. A comfortable vest and a reliable headlamp matter more than carbon poles or a premium watch.
  • Perfect training. Missing a week doesn’t ruin a 12-week block. Showing up healthy to the start line does.
  • Comparing yourself. Finishing is the goal for a first ultra.
Save your money

What you don't need yet

Beginners get pressured to buy a lot of stuff that doesn't help them play better. Here's what we'd skip on day one.

  • A carbon-plated or ultra-specific shoe — Your current trail shoes are fine for a first 50k. Switch only if they cause foot problems in training.
  • A GPS watch with 40+ hour battery — A basic running watch works for a first 50k. Battery life matters from 100k up.
  • Compression sleeves and recovery gear — There's little evidence they matter. Sleep and easy days do more.
  • A drop bag full of gear — Most 50ks have no drop bags. Learn what you need to carry first.

FAQ

Common questions

What counts as an ultramarathon?

Anything longer than a marathon (26.2 miles). The usual distances are 50k (31 miles), 50 miles, 100k, and 100 miles.

How much should I spend to start ultrarunning?

About $215-270 beyond shoes, at the lower vest price: a vest ($105-170), a headlamp ($70-80), fuel ($30-55), and chafe care ($10-30). Poles add $70-195 if your race has big climbs.

Do I need trekking poles?

Only for mountain races with long climbs. Flat or fast courses don't need them, and a few races ban them. Check your race's rules first.

How is ultrarunning gear different from trail running gear?

Trail running gear is built for runs of a few hours. Ultra gear adds a vest with more capacity, a headlamp for the night, a fueling plan, and chafe and blister care that matters past mile 30.
