Yesterday I came back from South-America. It was now a week ago since I have been in high altitude so therefore I was curious how many red blood-cells were still in my system. This morning I went for a 5k run along the creek in Nieuwstadt. As usual after not running for over 3 weeks the first few hundred metres go very easy since the body has no clue what actually is already happening to it.
I didn’t want to kill myself within the first kilometer, so I changed back to moderate speed. Strange enough my heart didn’t beat in my throat. My legs started to wonder what I wanted to do, but my breathing was normal. I really enjoyed the run and I hope that this next week I will still feel the extra oxygen.
