Muir Athletes & Ambassadors 

Elite Athlete

Timothy Olson

Mindful Mountain Ultra Runner

Timothy Olson is the two-time winner and record holder of Western States 100 Mile race. Timothy enjoys long runs up mountains, challenging his body, mind and spirit. He finds inspiration in the land, trees, mountains and wildlife, connecting with them on the run, feeling their energy, allowing him to run wild and free. He believes that by being connected to our earth and living consciously and mindfully, we can create vibrations to inspire individual and collective steps to heal, care and nurture our environment and ourselves. Timothy uses a daily meditation practice and has found the value of this practice to motivate, inspire and balance his passions of family, running, nutrition and mindful lifestyle. Timothy lives in Boulder, CO with his wife, Krista, and sons Tristan & Kai. Timothy and his family enjoy their travels throughout the world – exploring new trails and experiencing new cultures while letting the adventures of the mountains guide their journey.
