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.
For girls it's 2.5 miles, and boys, I think is 3.2 miles. And this is in the high school level.
Generally it is 3.1 miles, 6.2 miles, and up to 26 miles (marathon)
