5 K, It’s the perfect distance: 3.1 miles require relatively little build-up, the training doesn’t take over your life, and the race is over fairly quickly unlike the half marathon or marathon.
Training for a 5K
According to a runners world article I read , by logging only three or four runs per week, you can be ready to toe the line of a 5K in just five weeks.
If your goal is just to finish, your training runs should be at a comfortable pace. If you are aiming to beat a time then you should consider adding some faster training to your schedule, it is the best way to improve your speed and endurance.
Running Tip For 5K
Don’t start running at a fast pace. Start slowly and save energy for the last mile.
