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. Units are a display choice — leaderboards always compare like with like underneath.
What you get
Log the walk
Sync from Garmin, drop in a FIT or GPX file, or type it in. Rucking is unusually friendly to manual entry — distance, time and pack weight is the whole story.
See the log →Rank by what you carry
Leaderboards split by weight class — under 10 kg, 10–20, 20 plus — and by bodyweight and age group. A 60 kg walker never has to out-haul a 100 kg one to place.

779 km of the Camino Francés drawn on the real route. Everest by cumulative climb. Fifty-two rucks in fifty-two weeks. Progress you can point at.
See challenges →Pack it properly
Lay your gear out and get scored on load, balance and reach — where the mass sits, and whether you can get at the rain shell without emptying the bag.
Try the packer →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 row on every board carries its mark, so you always know which you are looking at.
