    The answer is 720 ways. The way this is calculates are through factorials. Kristen can go to any of the places for her first run, leaving 6 options. Next she only has 5 options, then 4, then 3, 2, and finally 1 option left. Therefore the way to calculate this is 6! (factorial) = 6x5x4x3x2x1=720 ways.
