CHARLOTTE, N.C. -- Hours after he was too ill to get back in his flawed race car Saturday night, Kasey Kahne of Enumclaw ran a Sunday 5-kilometer race for his charity in a shade over 22 minutes.
"That was the slowest I ever ran a 5K," Kahne said. "I'm definitely feeling the effects."
Kahne was physically sick Saturday night, and said he vomited once after his accident 124 laps into the Bank of America 500 NASCAR Sprint Cup Series race at Charlotte Motor Speedway.
Kahne was also sick of his race car, frustrated with running poorly and disgusted his brakes had failed for the third time this season -- and second time in three races.
Had he not been sick, Kahne said Sunday, he might have returned to the car after his Richard Petty Motorsports crew repaired some of the damage.
By that time, though, he was about 100 laps down. He was queasy, annoyed with the brakes and angry at criticism from an unnamed RPM employee.
So Kahne said no, he couldn't continue, and the team tabbed J.J. Yeley to finish the race.
"I was told that I needed to start doing my part, [that] is what one guy told me last night after the race," Kahne said at the finish line of the Kasey Kahne Foundation run that raised about $30,000.
"I'm not going to say names, but I was told that I need to start doing my part. I can't control the issues I've had this year. I don't know how many parts I've broke. If I really thought about it, I could come up with all kinds of stuff. You can't control that as a driver. I'm doing my part. I just need the car. I work as hard as anybody out there."
Kahne signed to join Hendrick Motorsports in 2012 this spring and will move to Red Bull Racing next year as a one-season holding spot before he makes his eventual move to Hendrick.
Kahne confirmed crew chief Kenny Francis will move to Red Bull with him, and that Francis will have the option of staying at Red Bull or moving to Hendrick in 2012.
Kahne seems miserable at RPM, where a year after making the 12-driver Chase, he is winless in 31 starts and ranked 21st in the standings. Kahne said he had never been so mad in a race car as he was Saturday.
"I lost it," he recalled. "I was just mad. I came into the race thinking we had a shot to win, thinking we had a good car in practice, we had a good shot. It went green. We were a little bit tight, but still actually passed cars and really felt good and then boom, my brakes are gone.
"It's not like you have half-brakes, like you can pump them. Your foot goes to the floor. It bottoms out. It's a joke."
Kahne said he thinks the problem is the brake fluid RPM is using.
