Should I Train By Time (Duration) Or Distance?

Why Your Plan Uses Time Instead of Distance

Your workouts are based on time (duration) rather than distance. This helps you train more consistently, safely, and effectively.

Consistent Progression

Training by time ensures each workout delivers the right training effect, no matter the conditions.

• Effort stays consistent across weather, terrain, and fatigue

• A 90-minute run means 90 minutes in the right zones, not chasing a set distance

• Reduces variability that can affect pace or distance

Reduces Overtraining and Undertraining

Duration-based training helps control your ramp rate—how quickly your training load increases.

• Keeps progression gradual and safe

• Lowers risk of injury

• Ensures you don’t do too much or too little

Works Better in Changing Conditions

The same distance can feel very different day to day.

• Hills, heat, wind, or trails can slow you down

• Time-based sessions let you train within your limits

• No pressure to hit a fixed distance when conditions are tough

Supports Smart, Long-Term Development

Focusing on time helps you build endurance steadily.

• Encourages consistent effort and pacing

• Helps develop stamina for longer events

• Prevents burnout from pushing for distance when fatigued

In Summary

Training by time keeps your progression safer, steadier, and more reliable. Follow the durations in your plan and let distance be a by-product, not the goal. This approach leads to stronger, healthier, and more sustainable fitness gains.
