Competitor bio:

Samir is a physician specializing in Internal Medicine who runs a private practice in New Jersey. He has completed marathons on all seven continents in addition to the North Pole and is a member of the Grand Slam Marathon Club. He has also finished all six World Marathon Majors, numerous ultramarathons, and multiple Ironman races. He pursues these challenges not only as personal accomplishments but also to exemplify healthy living for his patients and his two children. Samir is now undertaking the World Marathon Challenge in memory of his father, an avid traveler who recently passed away from malignant mesothelioma, a rare form of lung cancer. This endeavor serves both as a tribute to his father’s spirit and as a means to raise awareness and money for cancer research, supporting patients and families that go through their own cancer journeys. He is deeply grateful to his wife and family for supporting the countless hours of training that have made his pursuits possible. To Samir, every finish line he crosses belongs as much to them as it does to him.
