Tessa Barrett is the best high school female distance runner in the nation.
An achievement so difficult to achieve, yet so simply stated.
Seizing the moment at the midway point of the Foot Locker National Championship meet in San Diego, Calif., the Abington Heights senior ran away from the pack of regional champions and qualifiers and sprinted to victory.
About five meters from crossing the finish line, the future Penn State runner lifted her arms, breaking the tape for the 5,000 meters (3.1 miles) in 17 minutes, 15.4 seconds to earn the high school girls National Championship on a sun-soaked Saturday on the west coast.
"This is really surreal," Barrett said. "This is the best moment (of my career) by far. Never in my wildest dreams could I have imagined being a national champion.

"It's just an incredible, incredible feeling."
Already the PIAA Class AAA champion and the Foot Locker Northeast Regional champion, Barrett chose to use her endurance, but more importantly her speed, to overtake the lead group of fellow champions at roughly the first mile-and-a-half mark.
"I wanted to make sure that the first mile I was comfortable," Barrett said. "I felt good and thought that at a mile-and-a-half this was a good point to pick up the pace and see where everybody would go and who would go with me.
"I got out and then got one more challenge later in the race, and that was important to push me even more."
Once ahead, no runner could catch the fleet-footed Barrett.
With the fast pace and 70-degree temperatures wearing on the competitors, her turnover increased and her determination carried her into a steep hill in the final 800 meters. When Barrett reached the crest and Hanna DeBalsiof Westport, Conn., who battled her at the Northeast Regional race, tried to close, she turned into a sprinter.
Picking up speed down the hill, Barrett cruised to the finish, beating DeBalsi by almost 10 seconds.
"I kind of forgot about that hill, but I said to myself that it's not as tough as the hill of the Hershey course, so I just swept up into it," Barrett said. "Then I picked up the pace and felt very strong. You just try to keep pushing because you never know what strategy the other runners used and who may becoming up on you."
Nobody came up on her and the victory capped a remarkable cross country career filled with peaks and valleys that included adversity and success.
Last season, a leg fracture during the District 2 Class AAA cross country meet prevented her from earning a coveted gold medal during a record-breaking year.
After earning championships and shattering records through the indoor and outdoor track and field seasons, she carried her momentum and motivation into this fall. Barrett built on her incredible legacy by breaking course records during each regular-season cluster meet in the Lackawanna League, in capturing the District 2 Class AAA race and in winning the PIAA championship.
She qualified for the national race by winning the Northeast Regional in 17:32.3.
"This is indescribable," Barrett said. "I never thought anything like this could ever happen. It goes to show you that hard work can get you places."
Dallas senior Regan Rome placed 28th with a time of 18:21.2.
With Barrett's and Rome's contributions, the Northeast team won the championship with 26 points, outdistancing the West, which had 49 points.
