The pack test
Every wildland firefighter on the line passes the Work Capacity Test (WCT) each year. The arduous level, known as the pack test, is the one most people mean: a timed walk with a weighted pack. Here are the standards, what happens on test day and how to get ready.

The short answer
The pack test is a 3-mile walk on level ground carrying a 45-pound pack, finished in 45 minutes or less. That is a steady 15 minutes per mile, about 4 mph. You walk the whole way; running is not allowed. Fireline positions such as FFT2 and FFT1 require it every year.
The three Work Capacity Test levels
| Level | Test | Distance | Load | Time limit |
|---|---|---|---|---|
| Arduous | Pack test | 3 miles | 45 lb | 45:00 |
| Moderate | Field test | 2 miles | 25 lb | 30:00 |
| Light | Walk test | 1 mile | None | 16:00 |
All three are walked on level ground. Arduous is the level for fireline work: running, hiking and climbing, and carrying 45 pounds or more for long stretches over rough ground. Moderate and light cover support positions with less physical demand. The level your position needs is listed with it in PMS 310-1.
What happens on test day
- Health screening first. Most agencies have you fill out a health screening questionnaire before you test, and may ask for a medical exam depending on your answers.
- A measured, level course. Often a track or a flat road loop. The administrator gives the start and calls out times.
- A weighed pack or vest. The 45 pounds is checked before you start. Many test sites provide weight vests; ask whether you can bring your own.
- Walk the whole way. Running or jogging is not allowed. Keep a steady pace from the first lap rather than speeding up at the end.
How to train for the pack test
Start at least four to six weeks out, longer if you do not train regularly. The goal is to make a 15-minute mile under load feel comfortable.
- Find your starting pointWalk 3 miles on flat ground with no pack and time it. Under 40 minutes with no load means the pace is there; the work is carrying weight.
- Add weight graduallyStart around 20 to 25 pounds and add 5 pounds a week until you train at 45. Two or three loaded walks a week is plenty; rest days are when you get stronger.
- Train the paceOnce a week, walk the full 3 miles at test weight and test pace. Check your split at each mile: 15:00 or faster.
- Build the legs and backHiking hills with a pack, step-ups, lunges and core work make the flat test feel easier, and are what the job demands anyway.
- Wear what you will test inTrain in the footwear and pack or vest you will use on test day, so blisters and rubbing show up in training, not at mile two.
- Back off before the testKeep the last two or three days light. Eat, sleep and drink water the night before like it matters.
This is general fitness guidance, not medical advice. If you have a heart condition, an injury or other health concerns, talk to a doctor before you train or test.
Questions
Can you run during the pack test?
No. The test is a walk, and running or jogging is not allowed. Long strides and a fast, steady walking pace are how people pass.
What pace do I need to pass?
45 minutes for 3 miles is 15:00 per mile. Aim to train at 14:00 to 14:30 per mile so a slow stretch or a turn on the course does not cost you the test.
How often do you take the pack test?
Every year, at the level your position needs, to keep your qualifications current. You also take it before your first Red Card.
What happens if I fail the pack test?
Retest rules are set by your agency or employer, including how soon you can try again. Ask before test day so you know your options.
Is the pack test harder at high elevation?
Yes, and the standard accounts for it: NWCG applies altitude adjustments to the time at higher elevations.
