Choosing to DNF
The live athlete trackers make this a more challenging situation than ever before. Knowing that you are being followed by your friends, family, coach and potentially your competitors adds pressure. Some athletes enjoy the support - knowing that people are out there cheering for them. But when the trackers stops producing results - the stress level goes up for everyone. The athlete who can accept that magic doesn't happen out there on race day, and plans for an intentional DNF can alleviate a lot of pressure on themselves by making that tough decision in advance.
