If Luke Littler and Mo Farah both ran a half marathon, but had to stop every KM to check out 501 on a dart board, who finishes it first?

I asked ChatGPT: Mo Farah finishes first by a mile. Even with a stop every kilometre to check out 501 on a dart board, Mo Farah starts with elite endurance, pace control, and recovery between efforts. A half marathon is 21.1 km, so that’s 21 stops—but he’d still likely be running the actual distance vastly quicker. Luke Littler might gain time on the dart-board sections because he’d solve/check out 501 instantly compared with most people, but unless the dart challenge took far longer than the running sections, the fitness gap is huge. So unless the “check out 501” stop means actually throwing darts until finishing legs for several minutes each time, it’s still Mo Farah comfortably.
