While I have experience coaching all abilities, terrains and distances, I have a few things I specialize in. First, I have a passion for trail and ultra-races, and I love to share that with clients. I find that these races are often more about mental strength and problem solving than who is the fastest runner, and they provide a unique challenge to the athlete/coach team. I also have experience incorporating strength training to complement and improve running. I’m a busy, working mom myself, which makes me uniquely suited to help others incorporate training into their daily lives to become the best version of themselves. Finally, I have helped numerous beginner runners start with their training and understand the basics of running, which can sometimes be more complicated than you think.


I believe the athlete-coach relationship is the cornerstone of coaching. My goal is to understand you as a runner and a human so I can collaborate with you to make the best decisions for your training. I want to keep you healthy and injury free, maximizing consistency. The mix of volume, speed work and strength training depends on each runner’s goals, current fitness and outside obligations. Achievement is important, but so is maintaining the joy of running for many years to come.


I have been running for almost 30 years and coaching formally for about 6 years. With individual clients, I have helped them reach marathon PRs, finish their first ultra and improve their trail racing performance. I have also coached in-person groups from couch to 5k plans to speed training and track workouts. I’m also proud to say that my client base is diverse in many different aspects and I have found ways to relate personally to all of them.


I am a full-on running nerd with a passion for inspiring others, especially other women, in their running. I am a contributor to Trail Sisters online journal. I’m a little bit of a tree hugger and am happiest running in nature, especially the mountains.

I work full time, coach and train for ultras, and am wife and mom to two active boys. Although I’m not sure if you’d say I have “free time”, outside of exploring you might find me reading or napping on the couch while I pretend to participate in family movie night. While I don’t preach a specific diet to my clients, I am plant-based because it’s how I feel best. I’ve lived in Kenya for study abroad and Ghana during my Peace Corps service. Originally from Pennsylvania, I now call Arizona home.


I am a big believer of Jack Daniel’s methodology of the body reacting to and improving with repeated stress, paired with the proper rest and recovery, as well as the importance of specificity, especially as you near your targeted event. Easy days should be easy and hard days should be hard, and each workout has a purpose. I have also grown fond of the training philosophies of Megan and David Roche which focus on self-love, love of running and racing as a celebration. They also talk to the importance of balancing training-induced stress with general life stress.


I raced cross-country and track in high school and college and then stepped away from competitive running for a while. When I started back racing I did a few road 5ks and half marathons, and in 2015 did my first and only road marathon. I quickly discovered trail racing and after my first 50k in 2016 haven’t looked back.

In 2017 I won the Pennsylvania Triple crown of Mountain running which included a win at the Hyner 50k, second place at Worlds End 100k and fifth at Eastern States 100 miler. In 2018 I won the Insomniac Race Series in Arizona, finishing as first female and top three overall at each 50k race in the series. That year I also took 2nd place at Mogollon Monster 100. In 2019 I started through a rough patch, managing to land on some podiums but also landing in some issues with adrenals. 2020 brought the pandemic. 2021 brought a hard fall on the trail that resulted in a knee surgery. With a well-healed joint I am rebuilding my fitness and rediscovering the joys of racing in 2022.

    Coach Des has been an instrument of knowledge. Her expertise and ability has given me the confidence to train for my first 100 miler. Some might say I was already an “experienced” runner, but Coach Des’ training plan has already elevated my performance with proper programing including rest and not over-training. In my current program, I PR’d a marathon and won first place women’s overall in another race. Depending on your needs and wants, Des is highly approachable and has even started to coach my wife as a beginner runner too.

    Des is the first coach I’ve worked with, and I feel very fortunate to have found such a great match right from the start. She helped me achieve my goal of running Black Canyon 100K close to a specific goal time, while providing a training plan that made sense with my all-over-the-place work schedule. I’m not new to ultrarunning, but felt like I needed some more-experienced guidance for this particular goal. She’s very knowledgeable and supportive, and I’m continuing to work with her because it’s been such a great experience. I’d highly recommend her to anyone!

    I have had a great experience with Des being my coach! She has helped me reach my goal and work through some injuries. She is super attentive and has an open line of communication. I’m glad I found her as my coach and I hope to keep running under her trainings.

    I have been working with Coach Des for a few months now and I’m already feeling results of her training plan. She has been great at checking in, adjusting as needed, and working around my goals and schedule. I like the consistency and purpose she has given to my running.

    Rebecca Learned

    I’ve enjoyed working with Coach Des so far in my 50k training. She is responsive to my questions and need for advice. She helped me with some patellar tendinitis issues and tweaked my training schedule to accommodate for a week. She is encouraging when I need it. She’s given me good race fueling/nutrition advice. I didn’t want a coach that wants to always hold my hand, a “helicopter” coach. Coach Des has been exactly the kind of coach I wanted.

    Des is such a great coach to work with. She is the perfect amount of stern and understanding. Des’ communication is consistent and thorough. I am so fortunate to have found her and my running is improving every day secondary to her program. I feel I can accomplish all my crazy goals with her guidance.

    Desarae is an awesome coach. My goals were to run a 13.1 or more mile races each month but die to the covit 19 all the races were cancelled. She kept my training on point and I ran my first 50k. She has a strong knowledge on nutrition and running gear.

    Deserae is amazing. Attentive and thoughtful in her communication and keeps me accountable. She has given me tips on form and stretches; useful advise that I’ve put to use and it’s been great. Top notch coach and I am so happy I found her!
