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 to bring quality education to the running community.
Apart from being a health nerd, Eric loves the outdoors in any setting, exploring new places, and spending time with his family. He currently lives in the San Francisco Bay area of California.

Joshua Grubb: Running Coach
For 32 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 with numerous accolades. Along the way, coaching distance runners in T&F has produced many examples of success, 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 in local races to adults completing major marathons (e.g. Chicago, New York). So far, he has coached over 300 runners through multiple competitive seasons.
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.

Testimonials
A third of the way into half marathon training, I started feeling persistent calf pain. I didn’t know what else to do but call my doctor who just confirmed that I had a calf injury and to lay off it for 2 months—without any other guidance. Encouraged by Eric’s response in a Facebook group to a woman who also had an injury, I found my way to arc-running.com. Eric helped identify my injury as a calf strain and gave me a plan to recovery. He was there every step of the way. After we got my calf under control, I worked with Joshua who helped me develop a safe training plan to get me to the finish. Not only did I finish my race, I felt great after—with no pain! I learned so much about how to better strengthen my body for running and new ideas for training. I now continue strength training influenced by ARC Running exercises and, with Joshua’s help, have returned to my goal of a sub 2-hour half marathon! Thanks ARC Running!
I don’t consider myself a runner, though I did participate in some high school track and cross country before some back injuries became too limiting. Year later, I was very hesitant to take up running again, but I completed a running form analysis with the ARC Running coach, Joshua, a couple months before my marathon. Joshua gave me great feedback and tips on how to train and incorporate different exercises before my runs. Unfortunately, it wasn’t my back that ended up hindering my training, but major foot pain. I felt defeated. That’s where ARC Running came to save the day. Its physical therapist, Eric, deduced that my pain was from cuboid syndrome, and gave me a list of exercises that I completed religiously. Gradually, my foot began to feel better! Ultimately, with the support of ARC Running, I was able to finish my marathon! I’m so grateful for Eric and Joshua!
I began to experience knee pain while training for an ultra. About a month out from the race, I reached out to Eric for guidance. He directed me to one of the ARC Running recovery pathways, which helped me get to the starting line without further issues. I like how the pathways were very step-by-step with the instructions, pics, and videos helping a lot. Now the knee is doing great. I appreciate the help, and am still doing some recommended exercises to keep up mobility as I have a big race coming up soon.
I came to ARC Running because I was having consistent knee pain every time I ran. I also have four small kids and getting to a physical therapist multiple times a week isn’t really an option. I met with Eric virtually soon after reaching out to ARC Running. After going through some assessments, Eric figured that I had a slight hamstring strain that caused the knee pain. I would have never been able to self-assess that! We started physical therapy exercises and increased them each week, eventually leading to short, slow runs. In a few months I was completely pain free! The whole process was so easy and informative. I was even able to finish my marathon!
I recently experienced calf pain while training for a half marathon. I took a few days off and slowly ramped activity back up, but had no improvement. Without understanding what the actual problem was, it was a challenge to rehab appropriately. My partner, a runner and personal trainer, suggested I reach to ARC Running to get an informed opinion, which seemed much easier than trying to schedule a session with a local PT, navigate insurance, etc.
The initial virtual consultation with Eric was really easy to set up and proved insightful. Eric identified that the pain was related to some nerve tendinopathy, provided some action steps, and checked in weekly to ensure my progress and to increase the complexity of the rehab exercises. It’s been over a month, and I’ve not had any recurrences of the issue since being back into half-marathon training!
Having navigated a few injuries over the years, one of the key differences in working with ARC Running is that they are knowledgeable not just about physical therapy, but about running. Working with someone who understands runners really sets up the recovery for success—not just for getting back to pain-free running, but successful training. I highly recommend the services they provide, and will definitely reach out if I have issues again in the future.
While training for the New York City Marathon, I pulled my hamstring. This was painful, not just because it hurt, but also because it looked like I would not be able to run the marathon. I heard about ARC Running and scheduled a session with Eric who showed me the problem. He evaluated my flexibility and right away noticed that my quads were very tight—basically hard as a rock—which put more stress on my hamstring. The solution was to foam roll the quads, stretch, and complete some loading exercises. After a few weeks of this, the quads become much less tight. I still do this regimen and I have had no problems since.
When I reached out to ARC Running, I had just signed up for the Chicago Marathon and didn’t know where to start. I never really considered myself an athlete, despite having completed several half marathons, and usually experienced knee pain during the training cycle. One training cycle went so poorly that I took two years off running to rehab. So, I knew that if I was going to complete the marathon, I needed the help of a coach.
I reached out to several coaches, and the passion, experience, and general vibe of ARC Running’s Joshua Grubb seemed like a good fit. I started with a gait analysis and was advised on several changes to mitigate the recurring knee pain. As training progressed, Joshua set up personalized plans tailored to my lifestyle and goals. Any question or concern that I had along the way was met with thoughtful responses. Within a few months, I felt stronger than ever and was pain free! Later that year, I completed the Chicago Marathon feeling strong from start to finish. I learned so much this past year about how to improve my running form and safely progress loading to prevent knee pain. I am so thankful I found ARC Running!
