My training strategy of running until I was lost, finding a payphone and calling a friend or family member to fetch me, tracking my route backwards in the car to measure the distance I had travelled was not going to work when I moved to Sudan. Getting serious about distance, daylight and time was easy with my PolarF6... so much so that I entered, ran and finished the Boston Marathon! I love the fact that it files and saves workouts, so you can easily review progress and work out new goals each week. I have to pack light, but I always take my PolarF6.
