This is the first time the queen has been spotted riding since her five-week break from the public eye in December and January after suffering a "heavy cold."
Her Royal Highness made her first appearance since recovering form her illness in early January, as she attended church at St. Mary Magdalene in Sandringham, England, with her husband, Prince Philip.
