From elite Kenyans to weekend warriors, the <strong>80/20 Rule</strong> (Polarized Training) is the gold standard. To execute it, you need to know your exact numbers. What is your Zone 2?

The 4 Pacing Zones You Must Know

1. The Easy Pace (Zone 2) - 65% Effort

Purpose: Builds mitochondria, teaches body to burn fat as fuel.
Feeling: Conversational. Boringly slow.
Frequency: 80% of your weekly miles.

2. The Marathon Pace (Zone 3) - 75-80% Effort

Purpose: Specific race endurance.
Feeling: "Comfortably hard." You can speak in short sentences.
Frequency: Only during specific training blocks.

3. Threshold / Tempo (Zone 4) - 88-92% Effort

Purpose: Raises lactate threshold (the point where your legs burn).
Feeling: "Comfortably miserable." You want to stop, but you can keep going.
Frequency: 1 session per week (20-40 mins).

4. V02 Max / Interval (Zone 5) - 98% Effort

Purpose: Top-end speed and heart strength.
Feeling: Gasping. Can't talk.
Frequency: 1 session per week (short busts).

Strategy: The "Negative Split" Magic

Why do 90% of World Records involve a negative split?

Because running too fast in the first half of a race burns through your Glycogen stores (sugar energy) rapidly. Once glycogen is gone, you "Hit the Wall" (Bonk). By starting slightly slower than goal pace, you preserve glycogen, allowing you to unleash energy in the final miles while others are walking.

Example 5k PR Strategy:

Mile 1: 10 sec slower than goal pace. (Control adrenaline).
Mile 2: Goal pace. (Settle in).
Mile 3: 10 sec faster than goal pace. (Empty the tank).

How to Use the CalcUIQ Pace Calculator

Choose Event: 5k, 10k, Half, Marathon (or custom distance).
Input Time Goal: "I want to break 4 hours."
Get Your Splits: The tool prints out exactly what time you need to hit at Mile 1, Mile 2, Mile 3, etc.
Print & Tape: Write these splits on a wristband for race day.

Conclusion

Running is simple, but fast running is strategic. Respect the zones, trust the math, and the PRs will follow.
