Amber King

After finishing up her B.Sc and B.Ed in 2009, Amber moved to the U.S.A from Canada. Drawn in by dreams of climbing perfect cracks and exploring new areas, she found herself in a few new places like Utah, Washington, and Arizona. When getting to the San Juans of Southwest Colorado - she found home. Along her journey she discovered trail running as a new found love. Completing her first half-marathon, full-marathon, and ultra-marathon within one year, she continues her education in becoming an endurance athlete. When taking a rest day, she can be found playing with her pack raft or split boarding in the backcountry. When she is working , you can find her tinkering with experiments as a high school science teacher.
