RICHLAND, Wash. — Sarah Palin is taking a Thanksgiving break from her book tour to spend time with family in Washington and join a 5K run to benefit the Red Cross.

Palin detailed her plans Wednesday on Twitter.

“Much 2 b thankful 4 as Americans, most free people on earth! More opportunity 4 happiness/health/prosperity thx to our liberating Constitution,” she wrote.

About 25 Palin relatives had registered for the annual Turkey Trot on Thursday at Kennewick’s Columbia Park, said Heather Filbin of the Benton-Franklin Chapter of the American Red Cross.

About 2,300 people had pre-registered, with 3,000 runners expected to take part in the fundraiser.

Palin plans to have dinner at the Richland home of her aunt Katie Johnson, a sister of Palin’s mother.

She intends to resume her book tour Sunday, signing copies of “Going Rogue” at a book store in Richland.

Palin’s grandparents, Clem and Helen Sheeran, came to Richland in 1943 so he could work at the Hanford nuclear reservation.
