Texas Gov. Rick Perry went for a run Monday night in New Hampshire and then got a good night’s sleep ahead of Tuesday’s GOP debate.

Perry tweeted about the “great running weather” Monday night, and shared a picture snapped outside of the Lebanon Municipal Airport.

Perry’s son, Griffin, told ABC News that his father will be “well rested” for the debate. “Now [his] focus will be the debates, and when he gets focused, he can do anything,” Griffin Perry said.

Perry has fallen in the polls since the last GOP debate, less than three weeks ago in Florida, where his performance was widely panned. Tuesday’s debate is considered make-or-break for Perry’s campaign.
