How the Runeasi test helped Emily towards the Six Star Medal

Interview by Philip Cortvriendt – Runeasi expert

In April 2024, Emily Manzanares achieved a remarkable feat—winning her six-star medal during the Boston Marathon. But her journey wasn’t just about running; it was about strategic strength training guided by Runeasi. Join us as we delve into Emily’s story and explore how Runeasi played a pivotal role in her pursuit towards the Six Star Medal.

Six Star Medal for Emily Manzanares
Achieving the Six Star Medal

Hey Emily, How did your marathon in Boston go?

“My marathon experience in Boston was really good. Despite the tough course, I felt strong throughout the race. Crossing the finish line not only marked a personal achievement but also earned me the Six Star Medal for completing all six major marathons.”

How did Runeasi help with your marathon preparation?

“The focus Runeasi provided during my preparation was important. As a runner, I understood the importance of strength training, but it often fell by the wayside due to a busy schedule. However, when I received my Runeasi test results, I realized there was significant room for improvement—motivating me to take action.

During the program, I felt stronger, which was incredibly rewarding. Despite not achieving the strongest results initially, it served as a reminder to prioritize strength training. Throughout this campaign, I’ve made it a priority.

Runeasi played a pivotal role. The exercises were crystal clear—I knew exactly how to address my weakest point. Ultimately, the transformation was in my hands, and I embraced the challenge.”

Did you already do strength training?

“Before Runeasi, I did some exercises at the gym, but they weren’t specifically tailored for running. They were more generic, based on what I’d seen online or knew from my background. However, after taking the Runeasi test, everything changed.”

Running quality score after first assessment

“I realized that stability was my weakest link. It was eye-opening to try the recommended exercises for the first time. I couldn’t even perform a single-leg stand-up or squat effectively. But over the weeks, I saw improvement. My strength was growing, and that feedback was motivating.

The best part? These exercises were precisely what I needed—the missing pieces in my training puzzle.”

Were you surprised when you saw the results after 2 months of training?

“I was very happy. Initially, I knew I could have done more—perhaps increased the frequency from once or twice a week to two or three times. But even with my modest effort, the improvement was remarkable.”

Going from 23% to 72% in stability

My weakest link had shifted, which kept things interesting. It’s like discovering new exercises tailored to my needs. If you always stick to the same routine, progress can feel elusive. But when you challenge yourself with more difficult exercises, the leaps become evident. It’s like those huge steps you take to perform well in a marathon.”

Did you also feel a change in training?

“Absolutely. Over the two months leading up to the marathon, I noticed significant differences. Initially, I experienced minor pains—nothing severe, but enough to be noticeable. However, after incorporating the Runeasi exercises and maintaining focus, those discomforts vanished.

The transformation was twofold: first, during my runs, I felt more efficient. It’s like my body was working harmoniously, supporting my fitness goals. Second, post-workout recovery improved—I wasn’t plagued by those lingering aches anymore.

As for specific discomforts, my Achilles tendon was the culprit. It would come and go, especially in the lead-up to the marathon. But now? Completely gone. No more morning soreness. Runeasi made a real difference.”

Philip achieved a master’s degree in physiotherapy & rehabilitation sciences and has core expertise in the field of running, working with both recreational and elite runners. Philip has the unique role of educating Runeasi physiotherapists and helping them translate biomechanical insights into targeted strength and conditioning exercises- specifically on how they can improve their client care using scientifically validated biomechanical insights from our Runeasi analytics.


1. Global movement quality

Track and improve your client’s Runeasi running quality. Identify their weakest link with our advanced visualisation.

2. individual recommendations

Get individual training and cueing recommendations to improve your client’s weakest link.

3. Real-time feedback


4. Session trends

Learn more about your client’s running quality during daily training. Our session trends show when and where the quality drops with fatigue.

5. Quick comparisons

Compare pre-post data to show intervention effects on the movement quality. 


1. No motion artifacts. The Runeasi belt is secured tightly against the body and the skin to capture the actual movements of the body’s center of mass. Attaching or clipping the sensor directly to the pants would allow the sensor to wobble from side to side (i.e., measuring the wobbling of the pants, and not the human body.

2.  Easy to standardize the sensor’s positioning. The Runeasi belt makes it easy to consistently position the sensor close to the center of mass. Attaching the sensor directly to the pants would dramatically affect the reliability of the outputs as the height and tightness of the pants will affect the results. Moreover, these pants attachments often shift sideways while running which further decreases the data quality. 

 3. Comfortable to wear.  Hundreds of runners confirmed that they immediately forget about our belt while running. This allows them to move without any restrictions and allows us to capture movements that are representative of a client’s true biomechanics.
