Project Eclipse: How Shalane Flanagan Relied on InsideTracker to Run Six Marathons in Six Weeks

By Stevie Lyn Smith, MS, RDN, CSSD, CDN, December 20, 2021

InsideTrackerProjectEclipse_CW-09373-min-2Chasing big, wild, audacious goals is nothing new to Shalane Flanagan. This four-time Olympian, Olympic silver medalist, TCS New York City Marathon champion, World XC Bronze medalist, American record holder, Nike Bowerman Track Club coach, three-time New York Times best-selling cookbook author, and proud mom inspired runners and non-runners across the globe with her recent incredible running journey known as Project Eclipse.

After the announcement of a stacked schedule of fall dates for six major marathons, Flanagan saw this "total running eclipse" as an opportunity of a lifetime—she would run them all, in extremely quick succession. She set this goal to challenge herself and "to do something that makes others feel they can do anything." With a strong team behind her, including InsideTracker to help guide her nutrition, performance, and recovery, Shalane set out to run six marathons in six weeks: Berlin, London, Chicago, Boston, Tokyo (virtual), and NYC.

The racing began on September 26, 2021, when she toed the line at the Berlin marathon—but her inside story started weeks prior with baseline blood analysis from InsideTracker. Here’s what Shalane learned from testing with InsideTracker five times throughout Project Eclipse.


 

Takeaway 1: Little changes have big impacts 

It’s common to see runners look to improve performance and recovery by buying expensive running shoes or going hard every run while cutting corners on nutrition, strength training, mobility, and a proper training schedule. Shalane's blood work throughout Project Eclipse shows that the little, not-so-glamorous actions really pay off when done consistently.

Using her personalized action plan from her first test (done after returning from coaching at the Olympic games), Shalane began to adjust her nutrition and supplementation to support optimizing or maintaining optimized biomarkers directly related to performance and recovery. These biomarkers included hsCRP, a marker of inflammation, iron, cortisol, vitamin D, and vitamin B12. 

Adding some favorite recipes from her cookbooks set the groundwork for her body to take on the training, racing, and traveling before she even toed the line at Berlin. With each subsequent test, Shalane was able to adjust the foods she was eating, the timing of her meals, and her hydration in an informed way. 

What was Shalane fueling with? Of course, she dug into her cookbooks to grab some favorite recipes. Here’s some of what she used to fuel Project Eclipse:

  • Thai Quinoa Salad for managing inflammation 
  • Beef and Lentil Minestrone Soup for iron and fiber
  • Dark Chocolate Banana Superhero Muffins for an iron, magnesium, and zinc-rich snack
  • Sweet Potato Kale Superhero Muffins for a protein-packed and salty snack
  • Instant Oatmeal Mix during her travels to and from races
  • Race Day Superhero Muffins for an easy to digest pre-run fuel
  • Maple Turmeric Nuts for more magnesium and zinc and mitigating inflammation
  • Sweet Potato Chickpea Cakes for complex carbohydrates 

 

Takeaway 2: What gets measured gets managed

“At the beginning of the project, my fear was getting injured or too fatigued to complete the 6 marathons," says Shalane. Balancing her many roles in work and life while still chasing her performance goals was a big undertaking, and one she wanted to do smartly after her two reconstructive knee surgeries. Shalane noted that getting consistent feedback from her InsideTracker tests and action plan throughout Project Eclipse held her accountable to make solid choices with both her nutrition and lifestyle to support her performance goals and keep her healthy.

In her test after the Berlin and London marathons, a sharp increase in inflammation, stress, and muscle damage biomarkers provided a wake-up call for Shalane to focus on nutrient timing and recovery, especially knowing that the upcoming Chicago and Boston marathons would be incredibly demanding both physically and mentally. Shalane mentioned that her refueling began immediately after she crossed the finish line in Chicago and began her travels to Boston. Once in Boston, she continued to refuel, work with her physical therapist, and ice bath to get ready to race.

There was a large drop in biomarkers indicative of muscle damage and inflammation. Such biomarkers tend to peak 2-3 days post-marathon and drop back down around day seven, Shalane's results were a testament to her focus on tweaks to nutrition and physical recovery.

 

Takeaway 3: Think big picture

After retiring and taking a year off of running after her two reconstructive knee surgeries and facing her own struggles with mental health during the pandemic, Shalane fell back in love with running. Her subsequent recovery and return to running have helped her feel her best self again. When announcing her Project Eclipse plans, Shalane noted, “I want to do something that makes others feel that they can do anything. I want to help young women in sport realize the purity of the connection between physical and emotional health.” By building a strong foundation of long-term health, wellness, and resilience, she was able to achieve those goals.

When pursuing multiple big life goals as Shalane has, it’s easy to overstep, creating an unintended negative effect on health. An objective, analytical approach to monitoring the long-term wellness impacts of a high-performance lifestyle is essential to maintaining overall health while striving for performance goals. 

While an emphasis was placed on the biomarkers related to muscle health, inflammation, and stress, additional biomarkers essential to health and performance were also monitored. These included ferritin to assess iron status, vitamin B12, and vitamin D. Flanagan addressed these using her InsideTracker recommendations from each test to reach her optimized zones, making minor adjustments to her nutrition and supplement routine. 

By her final test just a few days after the NYC marathon, the biomarkers related to muscle health continued to decline and her cortisol levels had returned back to her optimized zone. By continuing to retest with InsideTracker, Flanagan will be able to continue to fine-tune her nutrition and lifestyle actions to prioritize her health.

How can the average runner benefit from blood testing?

While many won’t be running six marathons sub-3 hours over the course of six weeks, the benefits of regular InsideTracker testing are apparent for athletes of all levels. 

Here are the top lessons learned from monitoring Shalane’s blood biometric data throughout Project Eclipse that can apply to runners and athletes of all levels:

  • No change is too small. Oftentimes, it is the small but educated actions done consistently that have the greatest impact. 
  • Knowledge is power. By having both blood biometric data and physical feedback, Flanagan was able to make adjustments to nutrition, supplementation, and lifestyle without the guesswork.
  • You can reach your performance goals without sacrificing your health. Balancing work, training, and life stress is challenging for many. Oftentimes, striving for audacious goals can lead to injury, illness, or burnout. InsideTracker provides tools for individuals to prevent negative health outcomes while accomplishing performance goals.
