5K Positive Split Workouts

By Rick Morris

I’m sure you have heard of if not already practice 5K negative splits. The benefits of negative split training are well known. Well, how about positive splits? Are they valuable at all? The next time you enter a 5K race pay close attention to the start. You will see many runners sprinting away from the starting line. There’s a good chance that you’re one of them. I know I almost always push it hard, probably harder than I should, in the first half of a 5K race. The typical fast start of the 5K makes running positive splits a common occurrence. Those positive 5K race splits aren’t necessarily a bad thing. Several studies have shown than running positive splits often results in superior 5K performance.

Running positive splits isn’t something that many runners train for. But, if you are going to succeed with positive split racing you really need to practice the skill. Here are some 5K positive split workouts that will improve your ability to run hard at the start of your race and still finish strongly. Make sure that you are thoroughly warmed up before beginning these intense positive split workouts.
