Never run straight

Imagine a leg through 2 types of forest, first forest is slower than the second one. The straight line has an angle of 45° to the contour line. But is running straight the fastest way? You can imagine that it depends on how much slower the first forest is in comparison to the second.

I give the results of some easy calculations.

Conclusion: NEVER RUN STRAIGHT if the speed in the two forests is different. It's easy to calculate in a fast way while running. If you think the speed in first forest (50%) is 2 times slower than second forest (100%) you should aim at about 50% of the angle between red line and contour line.

Run fast but think even faster.
