Totally different and complimentary. Field events are a chess match, virtuoso performance punctuated by periods of silence, and allow the viewers total focus on a single athlete and what they can do, every aspect of prep and technique. The sense of competition is defined by the position of the bar or mark which represents the leader, except in Mondo's case where there hasn't been any such competition for years and he operates a purely exhibition event. But Milty, Tara etc don't get to do that.
Running is moving drama in which the tension is created by constant relative movement between athletes, sometimes screening the viewers in distance races, and rarely, mostly in JIngy's or Keely's cases now, a duel with the clock but still against the ghosts of Komen, Kratch etc.
The Pre meet particularly thrives on this juxtaposition and differential absorption. Despite the aura and centering of distance running, the Pre crowd certainly knows their field marks and is totally into e.g. Crouser and Kovacs or Taylor and Claye.
