Sarah Palin ran a half-marathon after giving a speech at a Tea Party rally in Iowa on September 4.
Palin ran unannounced in the "Jump Right in and Run" half-marathon sponsored by Storm Lake Running Club. She registered for the race under her maiden name, Sarah Heath, and listed her hometown as Des Moines.
News of Palin's participation in the race broke after Fox News' Greta Van Susteren posted a photo to her website of a runner she claimed was the former vice presidential candidate.
Hannah Campbell, webmaster of the Storm Lake Running Club, confirmed to the Des Moines Register that the runner was indeed Palin.
“No one in our planning committee knew prior to her half-marathon finish that she was even registered for the race,” said Campbell in an email to the paper.
Palin later confirmed reports that she was in Storm Lake for the race, writing a thank you to the town on her Twitter page.
"Thank you, Storm Lake, Iowa. You put on a great event & we loved meeting some great folks in your beautiful town today!" she wrote.
Palin -- who discussed her passion for running in an interview with Runner's World in August 2009 -- placed second in the 40- to 49-year old age group, finishing the race in 1 hour 46 minutes and 10 seconds.
