George Kittle says he’s running 16 mph in his rehab

49ers tight end George Kittle has targeted a Week 1 return since tearing his right Achilles in a Jan. 11 playoff game against the Eagles.

Less than three months from the season opener, Kittle is on track to do just that.

“I got a run today, hit over 16 miles an hour,” Kittle said on the Pardon My Take podcast over the weekend, via David Bonilla of 49erswebzone.com. “That was pretty sick.”

Kittle said the workout was held in cleats on a field, another positive sign in his return.

“I’m 21 weeks out, and I’m running over 16 miles an hour, so I’m having a great time,” Kittle said. “Single-leg box jumps. We’re cutting again. We’re having some fun.”

Kittle made a seventh career Pro Bowl last season despite playing only 11 regular-season games due to hamstring and ankle injuries.
