Hi, I’m Mireille!

Running is more than just logging miles. It’s about health, strength, and balance. As a certified running and AIP coach, I help athletes who:

  • Want a half marathon or marathon training plan that avoids burnout and injury.

  • Are tired of cookie-cutter running apps and need coaching that adapts to their schedule and lifestyle.

  • Struggle with fatigue, flare-ups, or autoimmune conditions but still want to stay active and achieve big running goals.

If you’ve been searching for an online running coach who gets it, you’re in the right place.

Runner Success Stories

  • A young woman with long brown hair, wearing a coral pink jacket, black athletic shorts, and a colorful shirt, is smiling and holding a medal after participating in a race. She has a race bib with the number 2125 and the name Vidalia. There are other people in the background, some with race medals, along a sidewalk lined with trees and a race truck.

    “Mireille is an excellent running coach! ”

    She goes well beyond "just" providing a training plan and offered the support, accountability and helpful tips I needed to hit my running goals. I had never worked with a coach before and didn't know exactly what to expect, but it was a really smooth and organized process. Mireille knows her stuff and I would highly recommend her as a running coach.”

  • Man standing on a winners' podium at the Georgia Marathon, holding a medal and smiling, with a banner in the background that reads 'Georgia Marathon and Half Marathon' and 'Dynamic Funds.'

    “Mireille has coached me across the miles to accomplish things I never dreamed I could. ”

    “Before working with her, I had never run a 5K or 10K in my life. Fast forward to today: I’ve completed countless half marathons (I’ve honestly lost track—if Mireille says it in the app, I just do it!), and three full marathons. I’m so grateful to have been introduced to her and can’t wait to see what goals we tackle next. To soar, surround yourself with those who push you to greater heights. Mireille is making me soar, and I’m all in for the journey ahead."

  • A woman smiling and holding two race medals, standing outdoors at a race event, wearing black athletic clothes, race bib number 2207, with other runners and event tents in the background.

    “Working with Mireille was one of the best decisions I’ve made”

    “She is understanding, listens to your goals, creates plans that work for your lifestyle, and she’s encouraging! There were definitely times I thought: “I don’t know if I can do this,” and Mireille pushed me to believe in myself. If you choose Mireille as your coach, it’s an investment you won’t regret!”
