Santa must've brought someone new sneakers this Christmas!

Just after the holiday, Reese Witherspoon and Jake Gyllenhaal were geared up and power walking the hills in Ojai, near Witherspoon's farm getaway.

The couple's surprise dates? Gyllenhaal's Zodiac costar Robert Downey Jr. and his wife, Susan.

"It was cute, they were all wearing hiking gear," says a source, "They seemed really relaxed. There were no kids around and they seemed like they were having a great time."

Not to fear, the couple brought Jake's dog and also squeezed in time to engage in another trademark routine: grabbing a morning cup of coffee together.
