Austin Gray is a Ninja coach from Longmont, Colorado.
Prior to competing, Gray had given away one of his kidneys to his lifelong friend, Kaylee Adams. Kaylee had suffered from Focal segmental glomerulosclerosis. Her kidneys were scarring over and no longer filtering blood.His motto is "Share Your Spare" to encourage kidney donation.
Austin first competed in Minneapolis in American Ninja Warrior 10. In qualifying, he failed to scale the Mega Wall, and was also unable to scale the regular Warped Wall. He still advanced to the city finals, placing 15th.
In the city finals, his run was digested but he fell on Iron Maiden and missed out on hitting the buzzer again, he still placed 12th overall and moved on to Vegas.
In the national finals, Austin ended up hitting his very first buzzer, finishing Stage 1 with 33.89 seconds left. He was also the first person that night to do it, as well as the first to hit a buzzer on Stage 1 that season to do it altogether.
He returned in Tacoma for his sophomore season. He was expected by several to go farther after a breakout rookie year. However, in a shocking disbelief, he stumbled on Broken Bridge, and was unable to recover, quickly ending his season.
- Gray is one of two competitors in American Ninja Warrior 10 to fail the Warped Wall in qualifying, with the other being Venn Johns. In both cases, this was due to the rule that season that failing to scale the Mega Wall would result in only one attempt on the 14'6 wall, which both were unable to do.
