How Long Does a Thru-Hike Take?

If you are excited at the thought of taking on the challenge of a thru-hike, welcome to the club! Completing a thru-hike can be a life-altering accomplishment, but it is critical to be prepared before attempting, for safety's sake!

Most thru-hikes take weeks or even months to complete and can require extensive planning and preparation. You need to research your chose trek to determine how many miles per day you intend to hike, the time of year, and the climate. Then you can plan your gear, food, and water needs, locate campsites, and towns to resupply.

Most hikers can comfortably and safely hike between 10 and 16 miles per day. If you want to take your time and stick to around 10 miles per day, divide your chosen route's total length by ten. For example, The Pacific Crest Trail is 2638 miles long. If you hike 10 miles per day, it will take you about 27 days to complete just the hiking portion. Add one day in town for every three days on the trail to get restocked, and you add another 9 days, for a total of 36 days.

These days in town are important to allow you to resupply, rest, and eat a few hot meals. While you may not need to stop every three days, you should incorporate some stops into your trip. Every 3 to 5 days is normal, except for extremely remote portions of trails or for hikers trying to break a record.

American Discovery Trail- 6800 miles

The ADT is a unique hiking trail, as it is comprised of multiple other trails joined by connector routes, not all of which are through the wilderness. While most traditional hiking trails tend to stay in nature, even when winding near a town or city, the American Discover Trail actually passes through towns, farmland, and wildlands on its coast to coast route.

Starting in Cape Henelope State Park, Delaware, and ending in Pt. Reye National Seashore, California, the American Discovery Trail passes straight through the heartland of America. There are actually two routes, the more northerly route is 4834 miles, and the more southerly is 5057 miles. They both begin and end at the same places, but you can choose which one you would prefer. The 6800-mile figure combines the mileage for both routes in the total.

This trail takes about one year to complete on average, so a thru-hike is definitely going to be a commitment, both personally and financially.

Great Western Loop- 6875 miles

It winds through 10 states and two deserts, the Mojave and the Sonoran.

It has only been completed by two hikers: Andrew Surka, in 2007, and Jeff Garmire in 2018, who completed it in 208 days.


Eastern Continental Trail- 5400 miles

The Eastern Continental Trail is another massive undertaking! It starts in Key West, Florida, and ends in Quebec, Canada. It encompasses several hiking trails, including the Appalachian Trail in its 5400 miles. It crosses 16 states and 3 Canadian provinces.

What do you need to pack for a thru-hike?

Knowing what to pack is essential to the success of your thru-hike. While the specifics will vary depending on each hiker, some items are mandatory for success. Remember, whatever you choose should be extremely durable, high-quality, and ultra-lightweight.


This should be in the form of a lightweight and easy to pitch waterproof tent or a hammock. This one-person tent from ALPS is only 4.2 lbs and is super easy to set up.

Getting adequate rest is important to your hike's success, and you will be exerting yourself to the max every day. A good quality bedroll or sleeping pad provides warmth and insulation between you and the cold ground like this one.

While you won't be carrying food to supply you for months, you will need to bring supplies for 3-5 days between stops to restock. Hiking burns a lot of calories, so it is important to pack nutrient-dense, high-calorie foods to keep you fueled. Protein bars, trail mix, and meals that have been dehydrated that you can add hot water to are great options.

First Aid Kit

On the same note, you should also carry a small first aid kit, like this one. If it doesn't have bug spray and sunscreen, be sure to add them to the mix as well.

Navigational Tools

While modern society has become accustomed to using our cell phones to get us where we need to go, there are many places in the wild where there is no service, so it is important to have alternate means to find your way. YOu should have hard copies of a trail map or guidebook, and a good waterproof compass at the very least.

Water Purifier

For most hikes, depending on the time of year, finding water in the wild is not an issue. However, it is ideal to purify the water before drinking it, so you don't get sick.

Fire Starter

The ability to make fire is crucial for cooking food, keeping warm, and warning away wildlife. Carry a waterproof firestarter, as you will inevitably be caught in the rain.

Which Thru-hike is the hardest?

The most difficult of these trails is the Great Western Trail. Not only does it have some difficult terrain, but the time constraints to complete it in season are not for the inexperienced hiker.

How Much Does it Cost to Do a  Thru-Hike?

The average cost for a thru-hike is between $1000 and $1200 per month, plus travel expense and gear.

What is a Flip Flop Thru-Hike?

Sometimes it does not make sense to start at one end of a trail and hike straight through to the end. The Appalachian Trail is a good example of this, as there are a lot of hikers. If everyone started in Georgia in February, then the crowds would be horrible, plus the masses of people would create environmental issues. A flip-flop thru-hike is where you chose to start at a point in the middle of the trail, hike to one endpoint, then travel back and do the other part of the trail. You still get to see the entire trail, but just in a different order.


Committing to completing a thru-hike can be an enormous undertaking, but if you are up for the challenge, it can be life-changing!
