Preheat oven to 400°; line rimmed baking pan with parchment paper. In small bowl, stir garlic, butter, thyme, salt and pepper; rub over all sides of beef.
With long sides of bacon facing short end of prepared pan, shingle bacon, making sure each piece slightly overlaps the last. Place beef on 1 long side of shingled bacon and roll up; place seam side down on pan. Rub bacon with brown sugar; roast beef 45 minutes or until bacon is crisp and internal temperature of beef reaches 135° for medium-rare. Transfer beef to cutting board; tent with aluminum foil and let stand 10 minutes. (Internal temperature will rise to 145° upon standing.)
