It looks like Jeremy Horgan-Kobelski picked up two wins at NMBS #5 in Brian Head, Utah over the weekend. He beat Geoff Kabush in both races (XC and Short Track). It was a big weekend for the entire JHK household as wife Heather Irmiger also won the women's XC race.
In the gravity events, Ross Schnell and Susan Haywood won the SuperD events (Team Motionbased has a great writeup on their experiences), while Ameil Cavalier and Melissa Buhl took the Dual Slalom. Melissa Buhl picked up another win in the DH competition, while Sam Hill took the men's.
UPDATE (08/08/06): Mountain Bike Action also has a round up.
