So I've been getting back into running. Trying to make sure I don't develop much chub from eating so much! Just wanted to share a couple odd things that have been happening with my body after being at such a high altitude for so long. 1. My heart rate is extremely low. I also feel really out of shape and when I run for 20-30 minutes I feel so exhausted, yet, my heart rate still remains below 100 bpm. Weird. 2. My breathing, even when I'm tired and exhausted while running, is super slow. It's strange because my muscles are cramping easily, which although it makes sense because they are asking for more oxygen, my body isn't breathing harder. I guess it's used to breathing a lot at altitude, and down here since there's a ton of air, it doesn't try at hard. Anyways, I don't know. But it's strange.
