THE CHALLENGES

100-metre sprint

Usain Bolt takes just 9.58 seconds but how quickly can we do it on a bike?

Figure-of-eight

Five laps threading between two cones: a torturous test of low-speed agility.

Top speed

No speed limits, no police — but how fast can you actually go given the chance?

Emergency stop

How much space do you really need to stop the bike from 60mph?

Slow race

Take as long as you can to cover 15m. To finish first, first you must finish last.
