Testimonials

  • Keri-Ann is the type of coach you need to succeed. Her coaching style is uniquely tailored to fit your lifestyle, time constraints, and personal fitness goals. The running plan she made me had so much variety that I was constantly challenged in a way that helped me get faster and perform on race day. Throughout the training process, she gave such great, personalized advice on gear selection, nutrition, technique, and many other areas. Thanks to her plan, I was able to beat my half marathon goal by 8 minutes. I can honestly say I will never have another running coach!

    -Brady G.

  • Coach Keri-Ann is awesome! Being coached by her has helped me develop as a runner and has reminded me to have fun with it! Not only am I having the most fun I ever have while running, I am also setting new personal bests. I have learned to trust how I feel on the run and stay flexible with the plan. Coach Keri-Ann is extremely supportive, encouraging and positive. She always checks-in and adjusts training when necessary. I am so grateful for everything she has helped me achieve and look forward to the future!

    -Allison Z.

  • Working with Coach Keri-Ann has been amazing! She's helped me improve my fueling and form, and I've hit three PRs in the short time working with her. I love the flexibility of each week's runs, and the support and interaction that she provides throughout the week. The training plans are right-sized for my fitness level and never seem daunting. I feel like I've known Coach Keri-Ann for years! If you're looking for a supportive and interactive coach, I can't recommend her and Mercuria Running enough.

    -Cara Y.

  • I’ve been running with Coach Keri-Ann since Summer 2020 and have felt a tremendous difference in my performance. She’s taught and encouraged me to trust my training plan, the process, and my body. Save the miles/effort for when it counts and enjoy each workout. She incorporates fun and energy into every workout and is always available whenever I need coaching support (questions about my plan, paces, etc.) or to encourage me. My current training plan is the perfect mix of challenge and fun and I’m learning that more miles don’t necessarily mean better outcomes. If you want a coach you can trust, who will encourage you to push yourself into the best runner you can be, and who is downright fun, choose Coach Keri-Ann. You won’t be disappointed, you might just PR.

    -Sarah G.

  • I've worked with Coach Keri-Ann of Mercuria for two running seasons now and I'm glad I found her. Before Coach Keri-Ann I went through a couple of other coaches and never really clicked, but Mercuria has a different approach to training that is more supportive and more flexible. Even though Keri-Ann is on the other side of the country from me, she still checks in many times a week, and before my races she really helps get me in a game day mindset. I plan on working with Coach Keri-Ann again, as soon as I find my next big race.

    -Andy G.

  • I can’t praise the coaches at Mercuria Running enough. I had the pleasure of working with coach Keri-Ann on my training to help me reach and shatter some big goals I had set out at the beginning of the year. All of the coaches at Mercuria are highly knowledgeable, detail-oriented, very helpful, and kind. Keri-Ann helped to custom tailor a training plan to fit my schedule, adjusting it as I progressed to train for a couple races. It all culminated in a great finish at the California International Marathon, far exceeding my goal for my first marathon. The coaches at Mercuria will help you work on your form, step up your PR’s, and help you conquer your next big goal!

    -Sergei
