Bike marathons have no set distance, like a running marathon (26.2 miles) There are set distances, such as a century (100miles) or half century (50 miles) But a bike marathon, is usually a distance set by whoever is running it.
it obviously depends how fast you can ride a bike and how long you can go without stopping
That depends on your speed.

Since a stationary bike doesn't move, there's no way it can travel 20 miles. Now, if you're asking how long it would take to ride twenty miles on a bicycle, it depends on speed, wind, and other factors. Typically a bike maximum speed is about 20 miles per hour. So it would take about an hour to ride 20 miles on a REGULAR moving bicycle.
It depends on how fast you can ride a bike!
24 minutes
about 2 hours
distance= 259 miles speed=75 miles time=distance/speed=3.45 hours
Time = Distance/Speed
The flight would take about 12 hours. The distance in between is 5702 miles.
A bike Trail is up to 1-10 miles long.
