Justin Homan raced AMA motocross and Supercross before moving into freestyle and riding with Metal Mulisha. He competed in Summer and Winter X Games and the Gravity Games, won the Malaysian X Games and developed the HolyMan trick. He was also among the first riders to land a backflip in competition.

He spent years taking Mulisha FMX shows on the road, including shows across the Pacific Northwest and appearances with Derek Garland. Through MX13 he put on demos as well as riding in them. He later developed the MX13 training facility in Redmond, Oregon, where he teaches motocross and freestyle, helping riders get comfortable on the bike and work up to harder jumps and tricks.
