I'm convinced the architect of the Dallas (DFW) airport didn't ride bicycles, had never learned to ride a bike as a child and in fact was unaware bicycles existed. The terminals straddle a purpose-built freeway...with left exits!...that provide the only roadway access. You might possibly ride from the terminals - a few folks have and most lived to tell the tale.
No matter. There are light rail trains running from near Terminals A/B, which one can reach via airport shuttle buses and internal circulator trams, to both Dallas and Fort Worth. From the Dallas line you can catch the "A Train" north to Denton to start your ride pretty much out of the megalopolis (locally called the Metroplex). From Fort Worth you can catch the Heartland Flyer Amtrak train north as far as Oklahoma City (with stops along the way) if you wanted to start that way.

You could pick this up in Purcell, Oklahoma if you go with the Amtrak Heartland Flyer option.
