The Story of Nyx

In ancient Greek mythology, Nyx was the primordial goddess of the night. She lived in the depths of the underworld, a place of torment, suffering, and darkness. She was the only goddess ever feared by Zeus, as she was older and more powerful. According to the myth, Nyx was one of the original elemental gods present at the beginning of creation. Before there was anything, there was darkness, or ‘night,’ and that is how Nyx came to be.

Darkness can be symbolic of fear and suffering, but it is also the platform for growth. There are highs and lows on the quest for endurance. There are moments in both training and racing where we reach a point of suffering that seems overwhelming, and there is a choice to be made. Do we slow down, quit, or resist? Or do we find a way to keep going.


Nyx inspires us to find our power by surrendering to the deep discomfort that comes with growth. When we’re at that point where we think we can’t go on, but somehow do go on, that’s where we uncover our potential. Because if you want to break through to the light, you have to be willing to endure the darkness.
