We have another hot lead on a new location for the Big Nasty Hillclimb and hope to make an announcement soon. Meanwhile, we hope to see you at our 3-mile Big Nasty Obstacle Adventure this Saturday. It is baked into the Oregon National STOL airshow, starting at 10am so that STOL fans can do the Adventure and then hit the STOL event about 300 yards away. STOL is excited about us, and we are excited about them! Come and watch Nampa resident win another STOL event. His piloting skills are mind-blowing. https://rrpromotions.redpodium.com/2025-big-nasty-obstacle-adventure

The weather is going to be GLORIOUS next weekend for the X-12 Hillclimb, at least on Friday and Saturday, but it ain't looking so good for Sunday. In the past, the only thing that we have run on Sunday are the 700 and Open Pro classes. So we are going to push them back to Saturday and scrap the Sunday racing, something that a number of pros have asked us to do over the years anyway, so they can get home sooner. If you are still thinking about entering in the pro classes, they are now ALL on Saturday and we have extended the entry deadline to midnight on Tuesday, April 29. www.x12events.com. All hills are marked and ready to go next weekend. The 1,025 foot trophy hill that hasn't been made since three guys did it in 2018, has been scooted over to the left into some pretty much virgin ground, which means less whoops. Maybe someone will finally make it over that beast this year.

FINALLY, X12, the world's tallest hillclimb event, and the last hillclimb left in Utah, has a return road. A huge helmets off to Tyrel Nish for making this happen. He has been operating heavy equipment since he was a toddler, including building fire breaks on some nasty Western wildfires, so he is used to extreme terrain, but he admitted that there were a couple of times that he was puckering while building this thing. It is STEEP up there! While he was at the hill, he tricked out the pro hill start and staging area, built a new burnout spot, and smoothed out the campground. This guy is a rockstar. Entries, tickets and camping passes are wide open at: www.x12events.com

FINALLY the world's tallest hillclimb WILL have a return trail in 2025. We are still finalizing the details, but we have a construction company (possibly more than one) that have committed to build our long-awaited trail in time for the 2025 X-12 Hillclimb, set for May 2-4. These things are challenging enough to run as it is, but when you have hills that are super steep and super long, it presents a huge challenge to get up or down without a road or trail. Finally having one will improve the weekend in a dozen ways. Our timeline to get it done will be tight. As this photo shows, the hills are still covered with snow and the event is only 6 weeks away, so our window to complete it is tight, but we'll get it done. www.x12events.com
