Here's why:
* Age Groups Vary: "Junior" is a broad term. Different organizations might define junior as ages 14-18, 15-19, or something else entirely.
* No Centralized Tracking: There's no single, official body that tracks world records for all junior 5K races.
* Race Variations: Even within a specific age group, there can be variations in course conditions, elevation, and race type (road vs. trail).
Finding Information:
If you're looking for a specific age group's fastest times, you can try the following:
* Check Athletic Associations: Websites like World Athletics (formerly IAAF) might have records for specific age groups in the 5K.
* Search Online: Use keywords like "fastest 5k times [age group]" or "5k records [age group]" to see if you can find results.
* Look at Race Results: Find websites for major junior races or local events.
