I am referring the the 97 switchbacks between Trail Camp and Trail Crest, which are the most challenging switchbacks on the Whitney Trail. With some altitude training, most hikers are able to reach Trail Camp without many problems. However, the 97 switchbacks take hikers through the 13,000+ elevation level, where they are more prone AMS and simple altitude sickness. These 97 switchbacks are also a psychological challenge because you can see Trail Crest from Trail Camp and realize the switchbacks are going to be a real pain in the ass. Conversely, reaching Trail Crest is a psychological boost as the trail from that point, even though more technically challenging, is less steep and you know you are closer to the summit. The pace card allowed my team to really take time to enjoy the mountain as we knew we were on pace to summit by noon and begin our descent before any afternoon storms claim the mountain. I began counting switchbacks out loud and my team quickly told me to shut up. I think most hikers find counting switchbacks counterproductive.
