Your mission...

Cycle slower than the speed of light

On this trail, when you cycle at your normal speed you're travelling at about ten times the speed of light. Can you travel ten times slower than you normally would without falling off your bike? Record your sub-light speed travel and send us the evidence.

Mission Information
This cycle route has models of the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto that are to scale both in size and how far apart they are. At this scale, you travel over 500,000km with one step!

Cycle Closer to Nature is supported by Arla's Kids Closer to Nature campaign and Sustrans. Search for this location on the National Cycle Network here.
