No, the maximum time per round is 2 hours. So you need to think less in terms of hours and more in terms of distance that you can cover for each round. Sometimes it is best to cover less distance in this round and conserve your health, so you can cover more distance in the next round.

For each round you all have 2 hours that you can use. You don't have to use all of the 2 hours however.

This is a turn based game, so think of the numbers you supply me as coming from the throw of a dice (except you get to decide what they are)

Because the terrain changes - remember this race is over some very big hills, you have to try ad figure out the most efficient way to cross the trail in front of you, and you can determine how much of the trail to cover (a bit) by how fast and and how long you run.

I hope that helps.
