Sunita Williams, a retired astronaut known for her remarkable achievements, is set to run the Boston Marathon for the first time in over a decade, reigniting her passion for the sport. Williams, who made history in 2007 by becoming the first person to complete a marathon in space, is looking forward to this year’s race on April 20, 2025. She previously participated in the renowned race on Earth in 2008, and now, with her return to the marathon circuit, her journey is capturing attention once more.
Having dedicated 27 years to NASA and taking part in numerous spacewalks, Williams is now embracing her latest challenge. “I’m gonna be trying to run the marathon; we’ll see if I finish,” she candidly expressed in an interview with the Boston Globe, indicating her enthusiasm mixed with an understanding of the challenges ahead.

Recently, Williams and her colleague Butch Wilmore were among the early astronauts to fly aboard Boeing’s Starliner spacecraft, arriving at the International Space Station in June 2024. Unfortunately, their mission was extended due to technical issues, delaying their return until March 2025. Reflecting on the experience, Williams acknowledged the discomfort that comes with uncertainty, stating, “Everybody wants the answer … and that just took a long time.”
Following her lengthy space mission, Williams has devoted the past year to recovering both physically and mentally. While in space, she maintained her fitness regimen by working out on the treadmill, a vital component of her training. Williams famously completed the Boston Marathon distance on the treadmill during her first mission, clocking in at a respectable four hours and 24 minutes.

The following year, she proved her stamina further by running the marathon in person, finishing with an impressive time of four hours and 20 minutes. Reflecting on the unique challenges faced by astronauts, she noted, “We’re strong because we have exercise equipment when we’re up there. But the things we lose are like your agility; your ability to do things fast—the little muscles aren’t getting exercise when you’re up there.”
Williams emphasised the importance of discipline and nutrition for astronauts, adding that with the right approach, recovering from time in space is entirely achievable. “If you’re diligent when you’re up in space, and you put in the work and use the nutrition the right way, you’re gonna come back and be okay,” she advised.
In addition to her marathon training, Williams has also expressed excitement about the recent Artemis II mission, which resulted in astronauts completing a lunar flyby for the first time in fifty years. The mission launched on April 1, returning to Earth on April 10 and marking a significant milestone in space exploration since NASA’s last lunar expedition, Apollo 17, in 1972. Williams noted the importance of success for this mission, stating, “We needed to get this one right. I’m excited for this next generation of explorers.”
Although she has retired from NASA, Williams remains dedicated to engaging in space exploration and educational initiatives, especially in STEM fields. “There are opportunities out there, maybe to work with some of these commercial companies,” she hinted, expressing her desire to remain involved in future projects.
Now residing in Maine, Williams is excited about participating in the Boston Marathon and reconnecting with the community of runners. “I’m a little slow, but I feel good and am happy to get out there to try it,” she remarked, showcasing her enthusiasm for the upcoming event.
As Williams prepares to run the historic Boston Marathon once again, her story continues to inspire many. Her dual accomplishments, both on Earth and in space, resonate with those who dare to dream and strive for excellence, proving that barriers can be broken with tenacity and passion.
