This June, Mammoth - A Climate Action Cinema is joining the Great Big Green Week 2026 and celebrating its third birthday with a whole week of screenings!

In 1973 a man in a little known American University set out to discover the most energy efficient creature on earth. The experiment has since entered into legend and is now more relevant to our world than ever before: a human being on a bicycle is the most efficient being on the planet.

The bicycle can enable ordinary people to do extraordinary things, like Chase The Sun- an event where people ride coast to coast, 200 miles or more in a single day, fuelled only by sandwiches, energy bars, cups of tea and good cheer. And it has the potential to do something much more extraordinary. At a time of energy crisis, of climate catastrophe caused by energy misuse, the bicycle can take a front line position in the fight against climate change. One pedal stroke at a time.
