Sam Bosco was six years old when she first got on a bike, riding to and from school with her dad. By nine-years-old, she purchased her first mountain bike, joined the Arctic Bicycle Club and was dreaming of becoming a professional mountain bike racer. She was born with a bowed tibia in her right leg and had that part of her leg removed as a young child. The resulting leg length discrepancy didn’t stop her from running or mountain biking. When she was 11, she had a limb-lengthening surgery go awry that left her with years of crutches, atrophied muscles and a surgically stunted left leg. After racing against able-bodied competitors in regional races, Bosco traveled to South Carolina with her mom to get classified in para-cycling and racing in the 2013 Para-cycling Open. She excelled, winning the women’s C5 road race. In 2015, she was in a car accident that left her with a concussion, putting a pause on training. She was cleared three weeks prior to road world championships and trained harder than ever to make a comeback. Rightfully so, Bosco secured a spot on her first Paralympic Team in 2016, taking two bronze medals in Rio.
