Herbold was born in Denver, Colorado.[1] He won the first dual slalom race at Mammoth Mountain in 1987. A year later, "Over the 1989 Labor Day weekend, September 2–4, around 1,500 mountain bike aficionados united under a blazing sun at Big Bear Lakes, CA, home of the NORBA National Championships... By Monday, the morning of the downhill race, many of the riders had gone, leaving the steep, technical 1,200-foot descent to the daredevils. Greg "Hair-ball" Herbold careened down the chute of deep ruts and shifting dust with hidden rocks to finish first with a time of 2:28... Herbold, on that fine line between finesse and out-of-control, also won the dual slalom event."[3]
He appears in the videotape "Battle At Durango: First-Ever World Mountain Bike Championships" produced by New & Unique Videos of San Diego and released in 1991.
After retirement from racing, Herbold worked in the cycling industry, at RockShox and later SRAM.[2]
