Zabriskie seriously injured his left leg and wrist in 2003 while descending Mill Creek Canyon near Salt Lake City when a vehicle pulled into his lane and collided with him.

Before Zabriskie had fully recovered from his crash in the Tour de France, a swinging glass door at a restaurant injured his hand badly enough to end his 2005 season.

Zabriskie's 2006 season started out well, with a strong 2nd-place finish in the February stage race Amgen Tour of California, 29 seconds after the winner, countryman Floyd Landis.

Following several mountain stages, including a ride up the Mont Ventoux, Zabriskie finished the race in 32nd place, behind winner Levi Leipheimer.

In February 2009, thieves entered Zabriskie's home while he was away competing in the Tour of California and stole thousands of dollars worth of racing equipment and Olympic memorabilia[10] and his Marvel action figure collection.
