While I enjoy running in general, it constantly and painfully reminds me of my physical limits. Despite my almost life-long relationship with running, I am embarrassingly slow and technically bad.

As the stubborn and competitive person that I am, being slow and bad at running does not stop me from occasionally reaching for the sky. My recent participation in the Green Power Hike, a 50km trail running race over the full length of the Hong Kong trail, across the rocky backbone of the island was an example for me testing my limits. The 24th edition of the iconic trail running event was my fourth participation. How would my lack of training, five years of age, and five kilogram body weight since my personal best in 2012 affect my performance?
