Rub roast all over with thyme paste and place on a large cookie sheet. Let roast sit for one hour to come to room temperature.

Grill for 30 minutes, flipping halfway through. Turn roast on side, place lid back on grill and grill for 13-15 minutes, turning on other side halfway through.

Let roast rest for 20 minutes or until internal temperature of 130°F is reached for medium rare.
