Grayson was inured in July during a Speedflying accident. He landed on his back going 40-60 miles per hour, shattering his L4 and L5. It was the 2nd or 3rd shuttle lap of the morning and he misjudged his altitude when coming in for landing. Landed on his butt/back really hard. He leaned up after the crash but was unable to feel or move anything below his waist, and unable to get up.

Grayson describes outdoor sports as “an integral piece of [his] day to day life”. He wants nothing more to return to this active lifestyle, just in an adaptive form.
