Cameron Hörst recently completed the hardest route of his climbing career: Big Bone (5.15a/9a+), a king line out Utah's massive Fynn Cave.

What makes his first ascent especially compelling isn't just the grade—it's the journey. Big Bone was a project that demanded years of training, 60+ working goes and redpoint attempts, countless setbacks, and a level of patience few climbers ever develop.

In this episode of the Training for Climbing Podcast, Cameron unpacks the entire process. We dive into the physical, mental, and tactical challenges of working a multi-year project, the breakthroughs that finally moved the needle, and the lessons any climber can apply to their own long-term goals—whether you're projecting 5.10 or 5.15.

One of the most fascinating takeaways is that the breakthrough wasn't a sudden gain in finger strength or power. Instead, it came from years of accumulated training adaptations, comprehensive energy system development, improved recovery, refined tactics, and learning when not to climb. Cameron shares how he finally broke through a plateau that had stalled his progress for multiple seasons.
