Living in Flagstaff for over 12 years has allowed me to learn from some of the top coaches in the world and train as a professional athlete alongside Olympians and World Medalists. I've experienced firsthand what it takes to train like an elite, and now I want to bring those insights to you. My approach is rooted in evidence-based training, but it's also about finding the joy and playfulness in running—because I believe that when you enjoy the process, the results follow.
Back when I was racing in high school and college, I cared too much about my PRs, and it created overwhelming anxiety that sometimes kept me from racing. But I learned to transform that stress into excitement and bring playfulness into my racing routine. Now, my goal is to help you find that same joy, whether you’re toeing the line for your first 5K or your next marathon. I’ll be there to cheer you on, push you when needed, and keep you grounded through it all.
So, if you’re ready to chase your goals with a coach who truly understands the ups and downs of the journey, I would be honored to work alongside you. I’m here to celebrate your wins, support you through the tough days, and remind you why you fell in love with running in the first place. Let’s pursue your potential together, find joy in the process, and see just how far we can go.
Happy running,
♡ Leah

She came prepared to our 'Training Plan Review' with great questions and really listened to my responses and my specific goals and history. After our review, she made lots of changes to the standard plan that I chose so that it is now really customized for me. I'm looking forward to a great training block and will hopefully break through the plateau that I have been stuck in the past 2 years. Pressure is on Leah :)

I’m finding I’m increasingly mileage and feel good and not injured. Great coach! Love her attitude and her positivity:)

When I started running with 40 years Leah's iFit 2 part 10k series was my first one to do after getting a new treadmill. SH kept me excited and motivated during the runs. Making the decision a year later to run a marathon I did a few months of her personal training program. I picked her because I joined the ifit videos. And she is just the amazing coach and person that you see on the videos and she helped me a lot. Now I am subscribed to her v.02 training plans.
I can't say enough positive things about her and her training plans. Definitely worth it.

I discovered Leah on my treadmills iFit program, after building my running fitness, I wanted more. As a mother to a 17yr old and a 20 month old, who works full time, I really needed more structure to my training to chase the goals I have.
I found Leah on Insta and the rest is history.
I have been following the program, the structure is great, program is super easy to use, noticing big changes to my running, love all the addition add-ons and couldn't be more stoked.
Once this 16 weeks is over, I will be looking at what I can do next to work with Leah again.

I learned about her through iFit, when I was using that service to get into running. She stood out to me because she's got a great mix of being motivational and down-to-earth. Plus a quirky, fun sense of humor and personality. Those are the traits that matter the most to me in somebody to be inspired by.
When she began offering training plans, I worked with her to prep for my first 10k. It was a great experience and I exceeded expectations. I did a similar plan for another 10k, and then worked with her to do my first half marathon! I was pretty nervous about the whole ordeal but once again, her plan more than prepped me. I did great.
When I consider I didn't start running until my late 40s, and now have done 10ks, a ton of 5ks, and a half-marathon, I'm really grateful for a trainer like Leah making it all possible. I'm now using her monthly subscription. In short, she's an amazing trainer, an awesome person, and I can't recommend her enough.

I hadn’t run seriously since high school and years of long hours at a desk had done a number on my body, leaving me prone to injury. Leah has had the patience of a saint, gradually increasing my mileage, incorporating strength training, and even helping me find an excellent physical therapist when I needed one. She is absolutely brilliant at crafting workouts. I don’t have fingers for all the occasions I was nervous about a session (threshold miles in particular), but she nailed the paces every time. She’s taught me to have more confidence in myself, and goals that seemed overly lofty a few years ago are now feeling tangible. She offers generous feedback, with tips on stretching, drills, nutrition, recovery and more. I am constantly learning new things. Highly recommend!
