Hi, I’m Mireille!
Running is more than just logging miles. It’s about health, strength, and showing up for yourself.
As a USATF Level 1 Run Coach, 80/20 Endurance Coach, and AIP Certified Nutrition Coach with a BS in Exercise Science and a Masters in Public Health, I help two kinds of athletes:
→ Runners with autoimmune conditions who are tired of training plans that ignore inflammation, fatigue, and flare-ups
→ All runners from first-time 5K finishers to marathon veterans ready to level up
I've been running for 15+ years, completed 14 marathons and 5 ultramarathons. I even ran from Boston to NYC — 200 miles in 11 days. I also live with Lupus. I don't just understand what you're navigating. I've run through it.
My approach is simple: train with compassion.
You're in the right place if you're:
→ An autoimmune athlete tired of choosing between your health and your running goals
→ Training for your first race and want expert guidance from day one
→ Chasing a PR or BQ and need a smarter, more strategic plan
→ Frustrated with cookie-cutter programs that don't account for your real life
→ Looking for a coach who will meet you where you are — every single week
Specialized Coaching for Autoimmune Athletes
Living with Lupus, Hashimoto's, Rheumatoid Arthritis, IBD, or another autoimmune condition doesn't mean giving up your running goals. As both a certified AIP practitioner and autoimmune athlete myself, I create training plans that help manage inflammation, prevent flare-ups, and help you perform at your best without compromising your health.
Here’s How We Do It:
Assess & Personalize - A personalized approach based on your fitness, health, and goals.
Train Smarter, Not Harder - Science-backed run training plans that improve performance without overtraining.
Strength for Runners - Customized strength training workouts designed to reduce injuries and improve running efficiency.
Race with Confidence - Whether it’s a 5K, 10K, half marathon, or marathon, I’ll prepare you to show up ready on race day!

What People Are Saying
"I went from not being able to run a mile without being really out of breath to completing the Rose Bowl Half Marathon and the Los Angeles Marathon. Every week was detailed, easy to follow, and any questions I had were answered right away. Overall, the best investment I have ever made. I feel more powerful, more motivated, and I finally really like running."
— Half Marathon & Marathon Finisher"After having a baby in August, I wasn't running at all and wasn't sure how to get back into it safely. Just ten months later, I not only completed a marathon but achieved a 20-minute personal record. Mireille understood exactly what my body needed as a new mom getting back into running, and her programming reflected that expertise. I can't recommend her highly enough."
— Half Marathon PR & Marathon PR"From the very beginning, I have felt supported in my run journey. From being able to do the most to having to pivot when my life changed, you have been there every step of the way. The accountability is necessary for me and really helpful. Overall I would rate this experience a 10/10. I am grateful for the opportunity to work with a coach who was so intentional with me and my life."
