“It was more water than I thought it would be,” Ed Carpenter said after being drenched by 10 gallons of cold water.

The only owner/driver in the Verizon IndyCar Series accepted an ALS Ice Bucket Challenge from Indianapolis Colts long snapper Matt Overton on Aug. 14 in Victory Lane at the Indianapolis Motor Speedway.

“I’ve been following (the Ice Bucket Challenge) on social media,” Carpenter said of the viral challenge, where people dump a bucket of ice water over their head to help to raise awareness for ALS, also known as Lou Gehrig's disease.  “I saw (Celtics coach) Brad Stevens do his and other various people complete it. My phone started blowing up last night when Matt Overton threw a challenge my way. I don’t know if mine was a cool as his, but my venue is way cooler.”

Carpenter, wearing a Verizon IndyCar Series firesuit and driving boots, accomplished the feat with an assist from Andretti Autosport’s James Hinchcliffe, who dressed as a member of the Indianapolis Motor Speedway Safety Patrol for the occasion. Carpenter then challenged former Butler men’s basketball star Gordon Hayward, and the Utah Jazz guard will have 24 hours to accomplish the feat or make a donation to the National ALS Society.

“It’s a funny thing that’s happening for a great cause,” Hinchcliffe said. “Ed texted me and wanted me to get in on the gag, and you know me, I’m all for a joke and laugh. The fact I got to dress in a costume was great, too.”

Carpenter, of course, is hoping his next visit to Victory Lane at the historic Speedway also will involve getting liquid poured over his head – a cold bottle of milk.

“Hopefully it’s not the last time I get something dumped on my head standing there,” he said.
