National cyclist Vincent Ang putting a different spin on the sport yesterday as he joined over 300 cyclists at the F1 Pit Building to generate electricity in a 24-hour cyclothon which kicked off at noon.

The cyclothon is part of the National Geographic Channel's Earth Day Run over the weekend to raise awareness on climate change.

Through 25 dynamo-fitted kinetic bicycle units, it aims to generate at least 33,000 watt hours of power in a day, which will be used to power events such as a movie screening.

This zero-carbon footprint initiative is an attempt to break a Guinness World Record set by Hong Kong Polytechnic students in 2014.
