It's in Edmond where he's found the coaches to take him to that next step. Head coach Carl Hawkins has helped Nixon and the rest of the Wolves immensely, but it's been LaMar Garrett who has catapulted Nixon to this spot.
Garrett, a Santa Fe and Kansas State graduate, has been the one helping Nixon learn everything there is to the long jump and high jump.
"I used to just run as fast as I could and then jumped," Nixon said. "He's really helped when it comes to technique and helping me understand why something is done."
Nixon made national news this year when he posted the second-highest decathlon score in high school history in April in California.
"He's such an inspiration," Santa Fe graduate Walter Henderson said. "He pushed me so much. You'd think you're working hard, but then you'd see Gunnar, and you'd know you could do more."
Henderson will attend Arkansas, and he credits Nixon for being a big reason that he is getting that opportunity.
Nixon isn't the lone Oklahoma being represented in the Youth Olympic Games. Edmond Memorial volleyball star Micha Hancock and Pawhuska's Sarah Tolson will also be participating. Tolson will be in the discus throw. Norman's Jessica Beed also qualified for weightlifting.
