Summary
Enter Oliver Horton, the high school Colorado phenom everyone will be talking about this season.
At just 17 years old and a high school junior at Coronado High School (in Colorado Springs), he is already a state champion, a sub-14:30 performer, and a name climbing the national rankings, having just become the 2025 Colorado 4A state XC champion.
He didn’t just become the first Colorado runner to break 15 minutes on the tough Norris Penrose course in Colorado, he obliterated the previous course record, clocking 14:48. (For comparison, 2024 NCAA 5,000 National Champion Parker Wolfe ran 15:10 in 2020).
He has benefited from the consistency of running for coach Lisa Rainsberger for the previous 10 years.
Oliver’s PR on the grass is a sizzling 14:23.9, which he ran this past September. On the track he ran 4:08.93 in the mile outdoors and 8:54.94 in the 3200m.
Every generation has its defining runner. For Colorado, for 2025, and maybe for the nation, Oliver Horton is making his case.
The records speak. The rankings confirm it. But the story behind it all? That’s what we’re digging into.
