Why You Struggle With Longer Intervals (And How to Fix It Fast!)

Are longer intervals a struggle for you? In this video, we'll explore why that happens and provide you with quick solutions to fix it! Improve your performance today.

If you're training for a sub-20 5K, but longer intervals like 5 or 10 minutes leave you gasping, this video breaks down exactly what's going wrong—and how to fix it.

You’ll learn how to identify whether it’s your lactate threshold, VO2 max, or speed endurance holding you back—and how to train smarter, not just harder.

Whether you're running 1-minute intervals with ease but falling apart in the 5-minute reps—or you're close to that 20-minute 5K barrier—this guide will help you target your weakness, rebuild your aerobic engine, and train with purpose.

In This Video, You'll Learn:
1. Why longer intervals are harder (and what that says about your fitness)
2. How to tell if lactate threshold is your limiting factor
3. The VO2 max trap: why short intervals feel fine
4. How to build speed endurance without burnout
5. Workouts that bridge the gap from short reps to full 5K race pace

Key Topics Covered:
• Sub-20 5K Strategy
• Longer Interval Struggles
• How to Train Threshold Effectively
• Building Speed Endurance
• VO2 Max vs Lactate Threshold
• Real Field Test You Can Try
• How to Run Faster Without Adding More Miles
