Understanding Running Race Workload Calculator

Running workload is not one number: weekly distance, quality concentration, long-run concentration, elevation density, frequency, and planned progression describe different stresses.

Volume Weekly distance stays primary.

Concentration Quality and long run are ratios.

Terrain Gain is normalized per km.

Plan Next week has an explicit delta.

Calculation method

How the calculation works

Separate weekly volume, quality share, long-run concentration, elevation density, and planned progression rather than collapsing training into pace alone. Divide component distance by weekly distance, normalize elevation and session volume, compute week-over-week change, and keep the load index formula visible.

Detailed calculation process

Decompose weekly running workload and planned progression

The default week has 45 km, including 9 quality km and an 18 km long run, 650 m gain, five training days, and a 49 km next-week plan.

General formula: Q = 100D_q/D_wL = 100D_l/D_wE = G/D_wD_session = D_w/dDelta = 100(D_next-D_w)/D_wI = D_w + 0.5D_q + G/1000I_next = I(D_next/D_w) Each ratio preserves a distinct workload dimension. The displayed index is a transparent comparison reference, not a physiological or injury-risk model.

What each symbol means

D_w, D_next Current and planned next-week distances (km).

D_q High-intensity distance (km).

D_l Longest-run distance (km).

G Weekly elevation gain (m).

d Training days in the week.

Q, L Quality and long-run shares (percent).

E, D_session Elevation per km and average km per training day.

Delta Planned distance change (percent).

I, I_next Current and scaled next-week load references.

Worked substitution with the default inputs

1. Calculate intensity concentration Q = 100(9/45) = 20%L = 100(18/45) = 40% Quality and long-run shares overlap conceptually if quality occurs within the long run; they are not additive categories.

2. Normalize terrain E = 650/45 = 14.444 m/km Elevation density permits weeks of different length to be compared.

3. Normalize session volume D_session = 45/5 = 9 km/day This is an arithmetic average, not an instruction for equal daily runs.

4. Calculate planned progression Delta = 100(49-45)/45 = 8.8889% The reference uses current weekly distance as the denominator.

5. Build and reconcile the load reference I = 45+0.5(9)+650/1000 = 50.15I_next = 50.15(49/45) = 54.6078 The index exposes its weights and should not be interpreted as a validated training-stress score.

The default week is 20% quality distance and 40% long run, averages 14.444 m gain per km, and plans an 8.889% distance increase.

Worked situations

Practical examples

Quality distance is 20% of the week.
The long run is 40% of the week.
The next-week plan adds 8.889% distance.

Better inputs

Useful tips

Compare with several prior weeks.
Keep intensity and terrain changes visible.
Reduce or stop training when health symptoms warrant professional advice.

Before relying on the result

Limitations and common mistakes

The load index is illustrative and not clinically validated.
Sleep, heat, surfaces, strength work, history, and health are excluded.
This is not an injury-risk prediction or coaching prescription.

Reference

Key terms

Quality distance: Entered high-intensity running distance.
Long-run share: Longest run divided by weekly distance.
Elevation density: Vertical gain per horizontal kilometre.
Progression: Next week relative to current weekly distance.

Important note

Calculated from the entered performance values using the displayed method. Health, fitness, terrain, weather, equipment, and event conditions can change real-world outcomes.

Frequently asked questions

Should quality and long-run shares sum to 100%?

No. A long run can contain quality distance, so the measures may overlap.

Is an 8.9% increase automatically safe?

No. Tolerance depends on individual context.

Why include elevation per km?

It separates terrain density from total distance.

Is the load index a standard metric?

No. Its simple weights are displayed for transparent comparison only.
