So staying at hotels and working out can be tough. Here are some outside options that I have found: Atlanta – Tribble Mill , Lawrenceville – 10 miles or so of single track trails. There is also a couple of miles of paved path for road bike riding. Grapevine – Rockledge Park , Lake Grapevine – Single Track MTB riding and trail running. The trail is 9 or 10 miles in length, so great for long runs or rides. Fort Worth – Trinity River Trail – Miles of paved trails for riding that goes from outside Fort Worth all the way into town. Arlington – River Legacy Park – DORBA maintains a 3 mile loop of singe track trails. OKC – Lake Hefner - Lots of paved trail around the lake, water stops every couple miles. Tulsa – Tulsa Cedar Creek Trail – Tulsa maintains paved trails for riding and commuting. Very hilly portions.
