What This Calculator Measures
Balance taper week training load using volume reduction and intensity targets.
By combining practical inputs into a structured model, this calculator helps you move from vague estimation to clear planning actions you can execute consistently.
This calculator models taper volume and intensity balance for race week.
How to Use This Well
- Enter baseline volume.
- Set taper and intensity percent.
- Add sessions and long run share.
- Review taper volume.
- Adjust for fatigue.
Formula Breakdown
Taper volume = baseline × (1 − taper %)Worked Example
- 60 km baseline × 70% = 42 km taper.
- 5 sessions = 8.4 km avg.
- 30% long run = 12.6 km.
Interpretation Guide
| Range | Meaning | Action |
|---|---|---|
| 10–20% | Light taper. | Minimal reduction. |
| 20–35% | Moderate taper. | Standard recovery. |
| 35–50% | Strong taper. | Extra recovery. |
| 50%+ | Deep taper. | Use carefully. |
Optimization Playbook
- Reduce volume: keep intensity steady.
- Adjust long run: shorten in taper.
- Watch fatigue: use fatigue factor.
- Keep sessions: maintain rhythm.
Scenario Planning
- Baseline: current volume.
- More taper: increase taper to 40%.
- Lower intensity: drop intensity to 70%.
- Decision rule: keep long run under 35%.
Common Mistakes to Avoid
- Cutting intensity too much.
- Not reducing long run.
- Skipping session count.
- Ignoring fatigue signs.
Implementation Checklist
- Set taper percent.
- Plan session calendar.
- Adjust long run.
- Review readiness daily.
Measurement Notes
Treat this calculator as a directional planning instrument. Output quality improves when your inputs are anchored to recent real data instead of one-off assumptions.
Run multiple scenarios, document what changed, and keep the decision tied to trends, not a single result snapshot.
FAQ
How much should I taper?
Most runners taper 20–40% of volume.
Should intensity stay high?
Keep some intensity to stay sharp.
What if I feel fatigued?
Increase taper percent slightly.
