×Navigate. Remember.
The complete desert intelligence stack.
PreRun.io gives you the best GPS navigation ever built for off-road. Off Com gives you the community memory that makes it smarter every season.
Live field reports · Danger zone heatmaps · AI build-route matching · Permanent course intel from every team that ran it before you.
The gap nobody filled
Navigation apps show you the route.
None of them know what happened on it.
Race teams, clubs, and hobbyists spend thousands pre-running courses. All that knowledge — every washed-out section, every false flat that eats differentials, every fuel cache location — lives in notebooks, WhatsApp chats, and the heads of guys who won't be around next season.

PreRun.io
Navigate the Course
Import any GPX. PreRun auto-detects every turn, grades severity, delivers live turn-by-turn GPS guidance on race day or pre-run day.
Your Club
Report What You Find
One tap from the trail: washed-out surface, dangerous rock face, fuel available, DNF zone ahead. Live field reports shared to the whole club in real time.
Off Com
Build the Community Memory
Every field report, danger zone cluster, linked build, and race result becomes permanent community intelligence — searchable, filterable, growing richer every season.
Race Teams + Clubs
Race Smarter Every Year
AI-powered Build-Route Match tells your specific rig if it's ready for this course. Danger heatmaps from crowdsourced reports show where finishes go to die.
PreRun.io does navigation. Off Com does community memory. Use both and your team gains an edge that money can't buy — collective intelligence that compounds every season.

Words from the desert
Legends who understood course intelligence
"The desert doesn't forgive a team that doesn't communicate. Every mile of pre-run intel is a mile of insurance on race day."
Ivan "The Desert Fox" Stewart
7× Baja 1000 Champion · SCORE Hall of Fame
"I ran the Baja course more than anyone alive. That knowledge lived in my head. Now it can live somewhere the next generation can actually use it."
Rod Hall
50+ Baja 1000 Finishes · Only American to win overall in a 4×4
"Your club is your edge. When everyone on the team can see the same intel — the same danger zones, the same surface reports — you stop guessing and start racing."
BJ Baldwin
Trophy Truck Legend · Monster Energy Racing
"KOH is as much about reading the terrain as it is about horsepower. Shared intel from guys who pre-ran that wash last week? That's the difference between a finish and a recovery bill."
Shannon Campbell
3× King of Hammers Champion
