For Quinn Sullivan, his final high school season is about more than times and placements. It's about solidifying his legacy.
The Niwot senior has already established himself as a top contender. Sullivan finished fifth at Nike Cross Nationals last fall, took third at the Colorado 5A Cross Country State Championships and owns personal bests of 14:34.48 for XC 5K and 4:03.93 in the mile.
There is still more that he seeks to accomplish.

"This senior season to me is a chance to leave my footprint," Sullivan said. "Of course that goes for multiple things, from team to state to national, it changes. In the end though this season is where I get to give the experience I have learnt to those younger than me while also shooting my shot to leave my footprint in high school cross country and track."
Final Season At Niwot
Sullivan is already off to another flying start. Most recently, he finished third at the stacked 2026 Desert Twilight XC Invitational in 14:35.90, helping Niwot capture its fourth consecutive Sweepstakes team title.
His range was on full display last spring as well, when he finished runner-up in the 800 meters at the Colorado State Championships in 1:49.08.
Sullivan has committed to Stanford University, where he will continue his running career after graduating from Niwot. But first, he has one more season with a program that means much more to him than results.

"Running for Niwot is one of the greatest gifts God gave me in my opinion," Sullivan said. "It gave me my friends, support system, and allowed me to fully chase my aspirations."
Sullivan also credited the Niwot coaching staff for helping create that experience.
"We owe much of it to our coaches who give us their time and dedication," he said. "I wouldn't trade them for the world."
Big Goals
The goals for his final season are clear.
"This final season I'm first and foremost looking towards the team," Sullivan said. "I think we can all agree we want to win NXN. We've set that as the standard and hope to continue that best we can."
Individually, Sullivan has his sights set just as high.
"For my personal goal I would like to win NXN as well, as I'm sure many of the other top runners will be aiming to do," he said.
But even with those goals ahead, Sullivan knows some of the moments he will remember most will not show up on a results page.

"In general though I look forward to the random moments," Sullivan said. "Those really are the best because fun happens in unpredictable ways."
One final high school season. One more chance to chase big dreams with Niwot.
And the opportunity for Sullivan to leave his footprint, on what has already been a remarkable high school career.
