In 2011, Alison Chow participated in the 38th Berlin Marathon. She finished the marathon in 2 hours 49 minutes and 57 seconds, 7 minutes slower than the Olympics entry requirement, thus the name of this documentary, Breaking 7. Alison gave up on her stable teaching job and left her comfort zone at the age of almost 30 just to follow her dream. She went through countless challenges with her coach, good friends and family, and was further inspired in life.

After six months of scientifically advanced training, three of the world's most elite distance runners set out to break the two-hour marathon barrier. These pioneers go on a global trek to defy the unthinkable and break the two-hour feat, from testing in wind tunnels and running labs in the United States, to balancing training with their day-to- day lives in eastern Africa, to the final heart-pounding race in Italy.

Facing the biggest challenge of his life, Sir Chris Hoy opens up about his journey with terminal cancer and how the mental strength he honed as a six-time Olympic gold medallist is now helping him to inspire others. Drawing on his Olympic career, Chris reconsiders his purpose and how he will choose to live with cancer – turning his focus towards raising awareness and inspiring others. The story follows Chris from the early stages of planning a brand new cycling event through to being joined by friends, including Sir Andy Murray, for the end result in Glasgow: the Tour de Four, a bike ride with the ambition to raise one million pounds for charity and show fellow sufferers that it’s possible to stay active throughout their treatment.
