The 100K runs the south shore trails above Big Bear Lake, out east to Sugarloaf Mountain and Balky Horse and back, then west over Snow Summit to Bluff Lake, Camp Osito and Aspen Glen before the Village. From alpine forest with towering pines to rolling singletrack, you get a variety of vistas of the mountains and Big Bear Lake. Finishing under 18 hours earns a 2027 Western States qualifier.
The race gives the 100K as 26 miles of dirt road, 31 miles of trail and 4.5 miles of asphalt. Big Bear sits at 7,000 feet and most of the course is higher, so the days are warm and the nights are cold: once the sun goes down the temperature can drop by as much as 35 degrees Fahrenheit. The course passes Bear Mountain twice, at miles 4.8 and 31.3, and Sugarloaf twice, at miles 10.9 and 25.2.
Kodiak runs on the trails above Big Bear Lake, in the San Bernardino Mountains a couple of hours from Los Angeles. The 100K, 50K, 21K and 10K all start and finish in the middle of the Village of Big Bear Lake, so the start line, the finish line and the festival are the same place. The courses climb the south shore trails: Snow Summit, the Skyline Trail, Bluff Lake, and for the 100K, Sugarloaf Mountain at 9,995 feet. Most of the running is above 7,000 feet, on dirt roads and singletrack through alpine forest, with the lake below you for most of the day.
The first Kodiak was run in 2013. It is now part of the UTMB World Series, and in 2026 it is the UTMB World Series Americas Major, which doubles the Running Stones a finisher collects. Finishing the 100K under 18 hours also earns a 2027 Western States qualifier.

These are other people's work and we link straight to them. Watching costs nothing and needs no account. More of them: every race we hold, on film.
Nobody sees it until we have read it. No account, no sign-in.
This changes nothing on the page on its own. Somebody checks it against the race first.
Somebody watches it before it goes anywhere near this page. What we are after is footage of this course, on the ground. If it would be just as true of any other race, it is not this.
We want the address of the file the race publishes, not the file. We download it from there so the page can say where the line came from.
We read every one of these and we write back. Every fact here carries the source it came from, and the way a wrong one gets fixed is a person checking it against what you tell us.
NavRun builds your pacing from your own training, then turns it into a plan your crew can follow: when to leave and where to park.
