GREAT WORK IS MULTI-FACETED
MAGNUM OPUS COACHING
Strategic, high-touch coaching for runners ready to tackle big goals without sacrificing their health or their enjoyment for running.

WELCOME TO THE WEB
Like the threads of a web, performance is interconnected.
Training, recovery, fueling, strength, stress, sleep, and everyday life don’t operate in isolation. Pull on one thread, and the others respond.
That’s why we coach the whole athlete.
At Magnum Opus, we help ambitious runners understand how these pieces work together, so you know when to push, when to adapt, what needs attention, and what doesn’t.
Because durable performance isn’t built by perfectly executing a training plan. It’s built by creating a system that can adapt to real life while continuing to move you toward big goals.
Your magnum opus, "your great work", is bigger than a single race or finish time.
It’s the athlete you become along the way.

Integrative Run Coaching
You have ambitious goals. You also have a full life. Your training needs to account for both.
We coach runners from middle-distance track to 100 miles, but distance isn’t what defines the athletes we work with.
Our athletes want to find out what they’re capable of. They care about getting faster, stronger, and more durable, but they don’t want to sacrifice their health, relationships, careers, or love of running to get there.
You might be chasing a PR, a Boston qualifier, your first ultramarathon, or a finish line that currently feels just beyond your reach. You’re willing to work hard. You just want to know that the work you’re doing is the right work for you.
That’s where coaching becomes more than a training plan.
We consider your physiology, training history, injury patterns, fueling, strength, recovery, stress, sleep, mindset, and the demands of your actual life. Then we continually adjust the pieces as you adapt.
The goal shouldn't be to execute a perfect plan. Our goal is that you become the kind of person and athlete who can keep progressing through imperfect circumstances.
HOW WE PROVIDE INTEGRATIVE RUN COACHING
Meet Coach Nelle



I’m Nelle, an endurance athlete, integrative performance coach, mother-runner, and founder of Magnum Opus Coaching.
I’ve spent more than a decade training and racing while navigating the same puzzle I now help my athletes solve: How good can I become without losing myself, or the rest of my life, to the pursuit?
My own running has taken me from road races and marathons to 100-mile finishes, podiums, setbacks, injuries, health challenges, and seasons when performance had to take a back seat to simply becoming healthy and strong again.
Those experiences shaped the way I coach.
I don’t believe better performance always comes from doing more. I believe it comes from understanding the athlete in front of me: their physiology, history, mindset, recovery, fueling, stress, responsibilities, and goals...and knowing which thread to pull or mend at the right time.
I coach ambitious runners who want to discover what they’re capable of and build a body, mindset, and relationship with running that can carry them there for years to come.
Intentional Training. Meaningful Results.
Reflections from athletes inside the Magnum Opus Coaching community.

KELSEY KADOW
Runner
Nelle is so helpful getting people prepared for races. While I have never been the fastest runner, I started going to run group in order to train for my first half marathon in 2022 and have now successfully done two full marathons since. I always look forward to the encouraging group runs on Saturday and have made some great friends since moving to the area because of it!

CASEY LUCAS
Runner
I have been working with Nelle for almost a year now. When I started with Excel Rock Town I had been coming off consecutive season-ending injuries putting me out of two club cross-country seasons at JMU. I was out of shape and I lacked a lot of my old self-confidence that I had in high school when I was a dual sport athlete. I also lacked self-confidence in my body in both the sense that it could keep me healthy and in the way it looked. Nelle helped me to understand both injury prevention when training and helped me conquer my fear of running a college 8k...

I am so thankful for Nelle's coaching and the supportive community she has cultivated through Excel Rocktown Running. Her positivity, encouragement, and welcoming attitude had me hooked after attending my first Saturday group run! Nelle helped me with a tailored training plan for the 2023 Harrisonburg Half and while I was pleased with my faster time in the race, I was even more pleased that with Nelle's help I was and am injury-free. Now, I'm training in a way that suits my hectic schedule and my goals and looking forward to positive, healthy, sustainable results.

Nelle was referred to me by my chiropractor. She thoughtfully designs workouts for my needs by corroborating with my Dr. and by perpetually seeking my feedback. Nelle is skilled in adjusting exercises on the fly as my changing needs require. Her studio is inviting, private, and clean. I’ve noticed a gain in strength over the past two months, and no longer take OTC painkillers since working with Nelle. She is willing to learn and grow alongside me as we work together to keep me active in this stage of my life.

DR. DAVID GLAZER
Nelle's top notch coaching helped me push the limits and run faster than I thought I'd ever be able to in the Shamrock Marathon. I ended up with a PR, beating my previous marathon by 32 minutes! Her background in movement and exercise training was helpful in allowing me to execute the training plan even when some aches & pains popped up. I highly recommend her whether you're a seasoned runner or just starting to run!
Nelle Fox and Magnum opus coaching are top shelf when it comes to training and coaching. Whether your goal is to get more movement, deal with injuries, or set new personal records, they are amazing to work with. Knowledgeable and supportive. Highly recommend
It is very hard for me to find words to describe how Nelle has touched my entire life over the past six months. She is kind, patient, knowledgeable and best of all enjoys what she does with a contagious energy! Thanks to her holistic, personalized approach, I have been able to improve my life style and my health both physically and mentally. A lot of people know her as "the runner" but she does way more than running, she is a great health coach and does personal training alongside coaching runners. She creates a safe supportive net for you, full of motivation and giving you reasons to love yourself again. When I started with Nelle, I could hardly move (highly overweight and multiple injuries) but she guided me every step of the way with...
