you're going to have to be a little more specific. are you talking about races or other distances? do you mean how long a season is? which school?
Middle school: 3k races, i don't know how long that usually is
High school: 5k races (3.1 miles), average finish time is 16-18 minutes, but it varies
College: 10k races, i don't know that either
A cross-country runner is a runner who trains and races in a long distance race. The distance are usually 5k and up.
In track and field there is a long distance heat. In the long distance heat the runner will run over 3 miles. It is not usually as long as a cross country run.
Running, track and field, road races, 5ks?
Running cross country is quite simple. the ultimate goal of the race is to get the lowest place possible. Cross country races can range from 3 miles to an 8k (5 miles) depending of level of competition.
It is not exactly clear when cross country skiing was invented as a competitive sport. It is accepted the first competitive races were held in Norway in 1879 and it has grown from there.
Generally it is 3.1 miles, 6.2 miles, and up to 26 miles (marathon)
There is cross country running, which is long distance running (4k, 5k, 8k 10k) k is kilometers. and there is also cross country skiing, which is long distance skiing.

It is unknown exactly when Cross Country was invented. This is because man himself have been racing against each other sense the caveman era. It was deemed to be "manly" to be the faster man in the tribe. Over time, the races became more sophisticated and organized, to the point of where it is at today.
Assuming that you are referring to the BMX races, 2008 is the very first year for the competition.
