Mark found running when he was 30 years old, but he instantly fell in love the sport because of its emphasis on focus and dedication. After serving roles as the Greater Lowell Road Runner club president, race team manager, and race director, Mark decided to start Marx Running & Fitness Center. Mark initially started the business in 2000 as a way to support athletes and give back to the running community. Since then it has transformed into much more than that. Mark has used his knowledge, experience, and passion for running to grow his business alongside with the local community. Mark has forged relationships with local road races, schools, gyms, doctors, physical therapists, and personal trainers, all of whom use Mark as a trusted resource when it comes to all things running/walking. Throughout the years, Marx Running has expanded in scope. As Mark has become an expert on foot pain and foot care, the store, too, has begun to cater to the needs of those in the therapeutic/rehabilitation establishment. He frequently gives seminars in gyms or PT offices on the importance of running/walking in the proper shoe. The Marx Running slogan, “A running store, and so much more…”, was inspired by Mark’s eagerness to not simply be a running store but a respected community resource.


After noticing he could outrun his teammates in the traditional sports, Bob began running and training on his own in the 7th grade. By 8th grade he was practicing with the local high school XC team and was one of their top guys. He ran XC/Track throughout high school and was recruited to run for East Stroudsburg University in Pennsylvania. While at ESU he was an ECAC Champion in the Indoor 1000 and the XC Team Captain senior year. Bob majored in economics and went on to do market research in the tech industry for 12 years. He then brought his 32 years of running experience to Marx Running where he particularly enjoys interacting with runners and walkers of all different ability levels and experience. Bob can draw from his lifetime of running experience to help customers get the most out of their own running or walking regimens. Bob is happily married with two children, ages 12 and 14.
