Rucking, measured
Carry weight.
Cover ground.
Keep the receipt.
Rucking is walking with a loaded pack. haultrek is where those walks become a record — logged, measured in kg·km, and ranked against people carrying what you carry.

The metric
One number for how far and how heavy
Distance alone undersells a heavy walk. Weight alone ignores the ground you covered. The haul multiplies the two, so a short walk under a heavy pack and a long walk under a light one can finally be compared.
haul (kg·km) = pack weight (kg) × distance (km)
Prefer imperial? The toggle in the header switches every number on the site to lb·mi — every example on this page included. Units are a display choice: the boards always compare like with like underneath.
Every ruck on the record, and a page for each one
Bring the FIT file off your watch, a GPX from anything that records a track, or type it in. Each ruck gets its own page — route, climb, haul — and moves everything else here: the boards, the challenges, the kit it was carried in.

Load ratio
612 kg·km in the last seven days against 498 kg·km in an average week. The injuries rucking is known for come from load added faster than the body adapts; this is the number that watches for it.

Three ways in

- GPX trackFrom anything that records one. The route and the climb come with it.
- By handDistance, time and weight. Counted everywhere, and marked as hand-entered.

Ranked against people carrying what you carry
A board of raw distance crowns whoever carries least; a board of raw haul crowns whoever is biggest. So there are four — overall, by weight class, per kilo of bodyweight and by age — and a 60 kg walker never has to out-haul a 100 kg one to place.

Distance × average load = haul. Check any row.
Honest boards
Verified and hand-entered, never mixed
A ruck that came off a watch and a ruck someone typed in are both welcome — they are just not the same claim. Every ruck carries its mark, so you always know which you are looking at.

Pack it right, pick a date, and do the maths first
Put your gear in a pack on screen and get scored on load, balance and reach — by physics, not a checklist. Pick an event and get a plan that fits its date. And when you want a number, the calculators show their working.

Move the Bladder, 3 L full (3.2 kg) against your back. Heavy mass down at the bottom pulls you backwards and down, and you spend the walk leaning forward to compensate.

Pandolf equation, not a flat multiplier
- Calorie calculatorHow much energy a loaded walk actually costs, from bodyweight, pack weight, pace, gradient and terrain. Built on the Pandolf equation rather than a flat multiplier.
- Pace and time plannerPick a speed and see the finish time, or pick a finish time and see the speed it demands. Splits, haul and energy cost for the same walk.
- Ruck weight calculatorHow much to carry, as a share of your bodyweight rather than a number somebody quoted you — with the 30% guidance ceiling marked.
- Rucking vs runningThe same distance, side by side: energy burned and peak force per step. Answers whether rucking really does burn as much as running, with your numbers.
- Progression plannerA week-by-week plan from where you are to where you want to be, that never adds weight and distance in the same week and holds every fourth.

Know-how
- What is rucking?Walking with weight is the short answer. Here is what makes it rucking, how it differs from hiking and weighted-vest walking, and what a first session looks like.
- How fast should you ruck?A useful pace is one you can hold without changing your gait. Use effort first, then learn what the clock means on flat ground, hills and event day.
- A four-week beginner rucking planEight deliberately unheroic sessions: learn the pack, add a little time, and finish the month ready to progress instead of ready to recover.
- Knee, shin and back pain from rucking: what to change firstThis is not a diagnosis. It is a triage guide: which training and packing variables to remove first, what should settle, and what deserves professional assessment.
Four journeys, in order
- 01Start with the walkWhat rucking is, how heavy to begin, what pace means and how to finish the first month intact.
- 02Build the weekProgress load, distance, frequency and terrain without quietly changing all four at once.
- 03Pack the loadChoose the carrying system, place the mass, adjust the harness and look after the feet inside the shoes.
- 04Stay durableTechnique, recovery, hydration and the early signals that should change the next session.

Glossary
- Haulkg·kmPack weight multiplied by distance. Sixteen kilograms carried ten kilometres is a haul of 160 kg·km. It exists because distance alone undersells a heavy walk and weight alone ignores the ground covered — the product is the smallest number that respects both.
- Weight classA band of average load: under 10 kg, 10 to 20 kg, and 20 kg and up. Here the average is weighted by distance, so a long walk under a heavy pack counts for more than a short stroll under a light one when deciding which band you are in.
- DeloadA deliberately lighter week — commonly every fourth — that lets connective tissue catch up with the muscle that adapted faster. Skipping them is how most people acquire their first rucking injury.
Put a weight in a bag and go for a walk.
That is the whole sport. We just keep score.
