As you can see there are three trainings per week. It's very important to rest between the trainings. You can go on Monday, Wednesday and Friday. Than you have the weekend off and on Tuesday and Thursday you don't have to run either.
The first kilometers are the hardest, but when you carry on you'll be happy at the end. You'll be very satisfied when you go in the shower. Before you go running you have to do a warmingup, and after you run you have to do a cooling down.
The warming-up exists of doing some stretching, while the cooling-down is walking and stretching. It takes about 10 minutes each.
