1.5 star star- finding road

You landed in a jangle;
Visibility is zero; You have a compass for directions;
You were told there is a road (perfect straight line) exactly 100 miles from you, where you will be rescued;

Q: what is the path you will take to find the road?
What is your distance of travel (for worse case)?
