SALT LAKE CITY — A Texas high school student came to the rescue of an exhausted runner last weekend at the BMW Dallas Marathon.

Seventeen-year-old Ariana Luterman ran as a pacer at the marathon. Luterman said in an interview with the Dallas Morning News' SportsDay that she joined Chandler Self for the last two and a half miles of the race. Then a nightmare came to life.

"I'm not really sure what happened," Self told SportsDay. "My legs started turning to Jell-O at mile 24. ... Then at mile 25.5, they turned to Jell-O so much that every step I took, they were giving out from under me."

"The only thing I could think of to do was to pick her up," Luterman told SportsDay.

With the finish line in sight, Luterman helped Self to her feet at every stumble. Self finished first in Sunday's race with a time of 2 hours, 53 minutes and 57 seconds.
