Games You Don't Think About #4: reach a top-speed on a bike

Toys
- a bicycle
- some sort of working speedometer (can be bought for £5) that shows the top speed and has been reset at the start of the game
- legs
- terrain
Winning Condition:
- your score is your maximum speed reached
Restrictions/Rules:
- you may not attach an engine to the bicycle - speed reached should be thanks to legpower and terrain.
Time to play:
- a game can range from a minute to a few days
Good points
- exhilaration from sensation of speed and wind in your face
- method of improvement is obvious (pedal faster/get bigger muscles)
- variance, in the form of changing terrain and wind conditions
- immediate feedback of score (the speed being near-instantly relayed)
- constant feedback of all other important factors (we can see the terrain changing or oncoming dangers; feel the wind or our muscles tiring)
Negatives
- possibility of death or injury, depending on location and lack of care taken
