Jul 27, 2012 - Pop Culture Software is pleased to announce 5K Challenge 1.04, for iOS devices. The app leads the user through a training program of about 30 minutes a day for nine weeks. After completion of the training, the user will be ready to compete in a 5K race. The program begins with interval training, alternating running and walking for brief periods. 5K Challenge lets you know how you are doing, with voice prompts counting down the time or distance, in yards or meters, left for the current section.
