Testimonials

  • “Thank you, Jenna, for all the hard and detailed training this summer. This was my first time ever using a coach for a race and I will absolutely do it again. Life and work get real busy and sometimes in the past my workouts would be an afterthought at the end of a long day. Having a specific detailed plan mapped out for me gave me a different focus I feel like I haven't had for the past few races. I went into Twisted Branch 100K feeling unstoppable. Let's do it again soon 💪"

  • “Without Jenna’s coaching I would not have been able to accomplish my goal of running my first ultramarathon. Before working with Jenna, I was training on my own and stumbling along. When I finally decided to work with a coach, a friend recommended Jenna and right from the start I could tell that her wealth of knowledge was what I was looking for. Jenna not only provided a running schedule, but a strength training plan, stretching plan, guidance on nutrition and fueling during a race, and overall race strategy. An ultra is about so much more than simply logging miles and without Jenna’s guidance across all areas, I would not have been able to accomplish this major life accomplishment of running 50 miles! I would recommend her to anyone looking to up their game and take on a major life challenge.”

  • “Jenna is top notch. The plan she provided me was personalized and worked with my hectic lifestyle. She listened to my needs and worked around my crazy hours as best as possible while still giving me a product that pushed me and made me better. If you're ready to commit to something that will improve your fitness, Jenna can give you that opportunity. I was able to shed 45 minutes off my 50k with 3 months of training. The numbers don't lie. Don't hesitate on talking to Jenna about your running goals because she can help.”

  • “By failing to prepare, you are preparing to fail.” – Ben Franklin "I had done several ultras in the past, finishing 6 and DNF-ing 3. But I always felt pretty horrible during and after them. I was training on my own but mostly “winging” it and going in under prepared. Then I got into my dream race, the Moab 240. For 5.5 months I hardly ran or trained, then reality began setting in. If I wanted to be successful and complete the Moab 240, I needed accountability and a plan. Fortunately, the algorithm also knew what I needed and an ad for Next Level Fitness and Coach Jenna entered my IG feed. Most running coaches have never run Ultras, but Jenna has, and that had me sold. Jenna got right to work on my training schedule. My plan was customized around my work schedule, and it included a race hydration and nutrition strategy, which I never considered before. Having a specific plan I didn’t need to think about was a relief. I was able to focus solely on completing every run and workout. Putting in the work, I leaned out and was completing long runs with ease. Going into the Moab 240, I felt strong and was confident I could complete the race. In just under 105 hours, I was able to complete the Moab 240! The best part, I never felt wrecked. From this point on, all my ultra-training will be managed by Jenna! Without her coaching I would not have made it 240 miles."

  • “As a fitness enthusiast and ex-crossfit athlete, I was VERY apprehensive about approaching distance running and ultramarathons. To be honest, I had no idea what I was doing but I knew I needed a new fitness goal and someone to guide me along the way. Jenna did EXACTLY that. She taught me about the rigors of training, the joy that comes with distance running, and showed me how wonderful the running community can be. My first attempt at the Leadville 100 Mile Trail Race, I tried to complete it all on my own with no coach. I was underprepared, under-fueled, and ended up having a horrendous race, pulling out at the 60 mile mark. The second attempt at Leadville 100, I had Jenna as my coach. With Jenna, I not only finished the race, but I ENJOYED it, something I never would have guessed after the horror of my first 100 miler attempt. Jenna is the real deal, through and through. You will not find a coach that is more in your corner!!!”

  • “I reached out to Jenna for coaching after running my first marathon. I wanted to start running ultras but didn’t really know where to begin. She specifically designed a program for me and the race I was going to attempt. She also helped me with gear, running shoes and race day strategies. The biggest thing that separates Jenna from other coaches is that she is an experienced ultramarathon runner who has put in the work. She has significant success through years of training/racing. She will get you where you need to be. Reach out to her today!”

  • “You don’t have to be an ultramarathoner to work with Jenna! I’m a less than one mile run kinda woman right now and my goals are more oriented towards strength and improving my frequency and confidence in gym visits. Jenna will meet you where you’re at and will always leave opportunity for you to seriously consider going harder but she doesn’t pressure you to do so unless you’ve agreed to that tactic. She’ll make sure you’re feeling good about the workout selections, that the movements feel natural to you, and that you’re doing them correctly/safely. You won’t find someone more committed and qualified to be your coach.”

  • "Wild Duluth 50K was no joke, but the views are so worth it. I would be remiss if I didn't thank Coach Jenna from Next Level Fitness for bringing the joy and passion back into my running. With that joy, I overcame some major blocks mentally. Without Jenna's week to week tutelage, I don't get the axe [finisher's token at Wild Duluth] or to 72 miles at Superior 100.
