Dr. Eric Lederhaus: PT, DPT, OCS

Eric is passionate about being a physical therapist. He is an extrovert, loves medicine, and is very curious about how to heal the body through movement. In 2009, he graduated from the University of Southern California (USC) with a doctorate in physical therapy, earning multiple awards while also co-authoring an article about posterior tibial tendon dysfunction. In 2010, he completed a year-long course for the spine at Folsom Physical Therapy, and in 2017 earned his APTA (American Physical Therapy Association) Specialist Certification. He continues to take educational courses in a variety of subjects to enhance his expertise.  

Eric has long enjoyed running, having completed his first half marathon in 2008. Throughout, he has been building his understanding of the sport, particularly injury prevention and recovery. He felt inspired to create ARC Running LLC to bring quality education to the running community.

Joshua Grubb: Running Coach

For 31 years, Joshua has nurtured a passion for distance running, competing in Cross Country (XC) and Track & Field (T&F) from middle school through college, currently focusing on running mountain trails and marathons (2:48 personal record at Boston). At Westmont College, he studied Kinesiology with an emphasis on coaching, which included building a practical understanding of injury assessment, rehabilitation, and conditioning while assisting the college athletic trainer for four years. This along with lessons from his own injury experiences has informed his holistic guidance of athletes. He continues to refine his knowledge of people and the sport through coaching and study.

In 2010, Joshua’s coaching career began as an assistant in high school XC in Colorado. The next fall, he became the head coach, guiding the men’s team to qualify for the state championship where their top runner placed 5th overall.

Returning to California, he resumed high school coaching in 2013, and in 2016 became the head coach for the men’s XC program, coaching the team to its first (and not last) state championship in 18 years. In 2017, the men and women’s teams were combined with him as program director, their roster averaging about a hundred athletes each fall. Along the way, coaching distance runners in T&F has produced numerous examples of successes, such as guiding one high school miler from a 5:46 to 4:08 within four years. Since 2019, he also coaches private clients, from middle school students to adults.

For Joshua, one gift of coaching is watching individuals fall in love with running, helping them learn how to navigate challenges with mounting self-awareness and wisdom, all the while seeing their performance improve. He enjoys many outdoor adventure activities and currently divides his time between California and England.
