Heat oven to 350 degrees F. Place roast in shallow roasting pan.
Combine thyme, olive oil, mustard, minced garlic, salt and pepper; spread mixture over meat. Roast meat about 2 1/2 hours (see cooking times below**). Remove meat from oven, place on serving platter, tent with aluminum foil and let stand 15 minutes.
Prepare the gravy by removing all but 2 Tablespoons fat from pan drippings and set aside. Set pan on stove top straddling two burners set on medium heat.
Whisk flour and broth together until smooth and slowly add to pan drippings; cook for 1 minute, whisking constantly. Add remaining pan juices and red wine; bring to boil stirring until mixture has thickened. Serve gravy with roast.
