Jim Walmsley and Jessica Brazeau are often on the go, especially in the summer. While they live in Flagstaff, Arizona, they’re often seen running through the mountains near Silverton, Colorado, hammering out long days on the Western States 100 course in California, and finding new and unique areas to train, adventure, and explore.

Getting to these high-altitude areas often requires a pretty burly vehicle, and the nearest town is often miles away. For this couple, it turns out the best combination of rugged durability, portability, and a fully outfitted home on the go comes in the form of a 1998 Toyota 4Runner called Casper.

Jim is one of the best ultrarunners in the world, best known for his multiyear wins and blazing fast men’s course record at the Western States 100, as well as his attempt to break the world 100k record at the Hoka Project Carbon X 2. He smashed the American record, and he missed the world record by only 11 seconds.

Jessica is also a highly accomplished trail runner, having won the 2021 Ultra Trail Cape Town 21k, placed second at the 2021 Canyons Endurance Runs 25k, and won the 2020 Speedgoat 28k.

Jim describes Casper as their “forever rig,” a never-quite-complete work in progress. Jim and Jessica bought Casper in 2018 from the original owner on Craigslist, of all places. It’s rare to find a vehicle, even modified, that can handle rough mountain passes and still be comfortable enough to live in for more than a week at a time. While most couples would settle for a van, most vans can’t make it over routes like Cinnamon Pass in Colorado.

“I chose this vehicle specifically because it can go anywhere and do everything,” said Jim. “This vehicle has been the cornerstone to our summer-long adventures around going to Western States, Silverton, and exploring Northern Arizona. It gives us peace of mind to not get in over our heads going to a destination while being able to bring an entire glamping setup in our vehicle.”

One of his passions outside running, Jim has made Casper the 4Runner a real lifelong project, talking with other overland and Toyota geeks to ever improve their respective rigs. So, what’s next for Casper, Jim, and Jess?

“Casper will see a little ski trip up to Tahoe, California, during the holidays, followed by some southern Arizona exploring during the next few colder months, [but] Casper’s purpose will always be built around taking us to the San Juans in July.”
