Retired pro skier Jessie Diggins recently completed the 100-mile Superior Fall Trail Race. Here is how veteran athletes balance extreme effort and longevity.
In September 2026, MPR News and NPR reported on the recent athletic transition of Jessie Diggins. Diggins retired from professional cross-country skiing in March 2026. Her departure concluded a dominant 15-year career that included four Olympic medals, one Olympic gold medal, and four overall World Cup titles. At 35 years old, she has now moved from elite ski racing into the demanding sport of trail running.
Her latest athletic target was the Superior Fall Trail Race. This roughly 100-mile event follows Minnesota’s Superior Hiking Trail from the Gooseberry Falls area toward Lutsen. The course tracks closely along the North Shore of Lake Superior and exposes runners to steep terrain, slippery sections, and substantial elevation changes. The rugged environment provided the exact type of extreme physical test she was seeking.
During the race, Diggins faced nighttime running and heavy rain. She ultimately became the first woman to finish the Superior 100. Diggins placed fifth overall in the event, completing the demanding route in approximately 25 hours. This achievement marked her third long trail race since retiring from professional skiing earlier in the year.
Despite her immediate success in ultramarathons, Diggins is deliberately avoiding the idea that she has begun a second professional athletic career. She describes trail running as something she currently does for enjoyment and personal challenge. She is treating the sport as a recreational pursuit rather than a new job. This intentional separation helps her preserve her love for extreme effort without the heavy burden of professional expectations.
This structured approach to voluntary hardship is not a new concept for her. The transition from elite skier to ultrarunner builds upon habits she formed years ago. During her active skiing career, Diggins reportedly selected one unusually difficult annual trail challenge. She referred to this grueling yearly event as the big stupid.
According to MPR News, her former coach Jason Cork provided valuable context regarding these massive annual efforts. Cork stated that the workout was not physiologically necessary for her conditioning as a skier. Instead, the massive run functioned primarily as a mental challenge and a highly meaningful personal goal. It offered her a psychological reset away from her strict, performance-driven training schedule.
Today, her primary professional focus has shifted away from the race course and toward the stage. Her post-skiing professional work is centered heavily on public speaking. She delivers talks on subjects ranging from grit and teamwork to mental health and eating-disorder experiences. She also frequently discusses her concept of the pain cave with these audiences.
Interestingly, the pressure of this new career rivals the tension of her athletic days. She has explicitly compared the nervousness of delivering a 45-minute speech in front of large audiences with the intense feeling of standing on a race start line. The psychological demands of performance remain, even as the venue has changed.
While her mental resilience transferred flawlessly to the Superior 100, the race exposed the stark difference between cardiovascular fitness and structural durability. Diggins experienced a serious blood blister and significant toenail problems during the 100-mile effort. The damage was severe enough that her support crew had to help her change socks and shoes during the final 20 miles.
The physical toll continued well after she crossed the finish line. After completing the race, Diggins reported that she could barely stand. She also stated that she could barely walk for several hours following the event. These realities demonstrate the heavy physical cost of treating a recreational challenge with professional-level intensity.
For ambitious endurance athletes aged 35 to 65, this story highlights the necessity of managing athletic transitions intelligently. Superior 100 race director John Storkamp emphasized to MPR News that completing the event is a test of mental and emotional readiness as well as physical preparation. Storkamp noted that Diggins’s skiing background prepared her well for the race because she is highly capable of grinding through prolonged difficulty.
However, veteran athletes must remember that massive aerobic capacity does not protect older joints from unfamiliar impact forces. Skiing fitness builds a massive engine, but trail running introduces heavy foot loading, terrain changes, and intense downhill stress. Athletes focusing on returning to endurance training after illness or transitioning to new sports must build their structural tolerance gradually.
Our team has learned firsthand how vital it is to respect the gap between cardiovascular ambition and structural recovery. Hitting my forties brought a harsh reality check regarding my own training limitations. The track workouts were not getting slower, but the days after them felt significantly heavier. My lungs and heart were ready for more work, but my tendons simply could not recover at their historical rate.
Rather than forcing my old Tuesday and Thursday intensity schedule, I looked at the data on Masters athletes and muscle protein synthesis. I pushed my second hard session to Friday, allowing an extra forty eight hours of low intensity recovery. My total weekly volume stayed the same, but the quality of my intervals skyrocketed. Adapting to our physical reality is essential for long-term athletic success.
We must apply that same critical thinking to how we manage discomfort during long events. Diggins continues to use the phrase pain cave to describe the point at which an athlete must manage extreme discomfort and continue functioning. She argues that voluntary racing allows people to practice coping with severe difficulty. This mindset builds incredible grit, but older athletes must handle the concept with care.
When recovering after an endurance event, we must distinguish between standard muscle fatigue and structural injury. Pushing through severe foot trauma during a voluntary race carries recovery costs that can sideline a veteran athlete for months. Persistent, sharp, or function-limiting pain should always be treated as a medical signal rather than a test of mental toughness.
The Superior 100 also underscores the importance of logistics and support in ultra-endurance efforts. Diggins’s crew was crucial for managing her foot problems during the most difficult miles of the race. Ambitious events require comprehensive planning for footwear, fueling, navigation, and emergency contingencies. Attempting extreme distances without a solid support structure is an unnecessary risk for older athletes.
Ultimately, the strongest lesson from Diggins is the immense value of preserving play in our athletic routines. She has explicitly stated that athletes cannot choose when life will become difficult, but they can choose to enter a race and develop skills for managing adversity. By treating her current races as optional rather than professional obligations, she reduces burnout and performance anxiety.
We can emulate this approach by building a sustainable training week that balances intense goals with genuine enjoyment. Ambitious adults can remain competitive by selecting one challenging event per season without tying their entire identity to the outcome. When we remove the pressure of professional validation, we can focus entirely on the personal satisfaction of the effort.
True performance longevity requires treating extreme endurance events as chosen adventures rather than compulsory tests of our athletic worth.
