Why perform the 1km and 3km tests?
The 1km and 3km tests are essential tools for measuring different energy systems. The 1km test is a great indicator of your anaerobic power and maximum speed. The 3km test falls into a zone that demands a lot of your VO2 Max and high-intensity aerobic endurance.
How to use these results in your training?
By discovering your pace in these tests, you can define your training rhythms more accurately. For example, runners often use the 3km pace as a baseline for long interval training (sprints). Repeating these tests every 4 to 8 weeks is the best way to validate if your training plan is actually working.
