TODAY, CROSS-TRAIN, OR RUN THREE MILES AT AN EASY PACE: "Cross-training" is any non-running activity that helps your training, such as cross-country skiing or running in the water. Keep the level fairly easy. On Day 1 of most training weeks, you'll have the option of either cross-training or running 3 or 4 easy miles. Do whichever would feel better and would be more fun.
