Calculator guide

Understanding Race Recovery Planning Calculator

A post-race recovery plan combines distinct entered references: race load, fluid replacement from measured loss, carbohydrate and protein multipliers, sleep opportunity, and easy movement. These quantities should not be collapsed into one readiness score.

No composite score Different recovery quantities retain their units.

Inputs are explicit Loss and multipliers are user-provided.

Time is accumulated Nightly and daily plans scale across days.

Dashboard is live Every dose and timeline marker updates.

Calculation method

How the calculation works

Keep race load, entered fluid-loss estimate, nutrition multipliers, sleep opportunity, and easy-movement plan as separate recovery references. The fluid-per-hour reference uses a strictly positive race duration and leaves nutrition, sleep, and movement separate. Normalize race time by distance, scale entered fluid loss by a replacement factor, multiply body mass by nutrition targets, and accumulate sleep and easy movement across recovery nights.

Detailed calculation process

Translate race load into separate entered recovery quantities

The default plan covers a 21.0975 km race in 110 minutes for a 72 kg athlete, with 1.8 L estimated fluid loss and three recovery nights.

General formula: pace = T/DF = L_f r_fC = m cP = m pS = h_s nE = e nH_ref = T/60 + SF_rate = F/(T/60) Each result keeps its own unit and basis: pace uses race distance, fluid uses measured loss and the entered factor, nutrition uses body mass, and sleep and easy movement use the number of planned recovery nights.

What each symbol means

D, T Race distance (km) and duration (minutes).

L_f, r_f, F Estimated fluid loss (L), replacement factor, and entered replacement target (L).

m Body mass (kg).

c, p Entered carbohydrate and protein targets (g/kg).

C, P Calculated carbohydrate and protein quantities (g).

h_s, n, S Sleep hours per night, recovery nights, and total sleep opportunity (h).

e, E Easy-movement minutes per day and total planned minutes.

Worked substitution with the default inputs

1. Normalize the race load pace = 110/21.0975 = 5.21389 min/kmrace hours = 110/60 = 1.83333 h Pace and elapsed hours describe the entered race without inferring physiological strain.

2. Calculate the entered fluid target F = 1.8 L(1.25) = 2.25 LF_rate = 2.25/1.83333 = 1.22727 L per race hour The per-hour value is a normalization of the entered post-race target, not an instruction to consume it during the race.

3. Calculate nutrition quantities C = 72 kg(1.1 g/kg) = 79.2 gP = 72 kg(0.3 g/kg) = 21.6 g Kilograms cancel against each entered grams-per-kilogram multiplier.

4. Accumulate recovery opportunities S = 8 h/night(3 nights) = 24 hE = 25 min/day(3 days) = 75 min Sleep opportunity and easy movement remain separate planning totals.

5. Reconcile the time reference H_ref = 110/60 + 24 = 25.8333 hcheck: 3(8 h) = 24 h and 3(25 min) = 75 min The combined reference is arithmetic only and does not convert the plan into a recovery-readiness score.

The defaults produce 2.25 L fluid, 79.2 g carbohydrate, 21.6 g protein, 24 h sleep opportunity, and 75 minutes easy movement.

Recovery dashboard

Keep fluid, nutrition, sleep, and movement on their own scales

A four-lane plan shows entered quantities and timing without implying that unrelated units can be added into one score.

Fluid lane Loss multiplied by replacement factor.

Nutrition lane Separate carbohydrate and protein amounts.

Sleep lane Opportunity across recovery nights.

Movement lane Easy minutes across planned days.

Worked situations

Practical examples

The entered half-marathon pace is about 5:13/km.
A 1.8 L loss with factor 1.25 produces a 2.25 L reference.
Three nights at eight hours provide 24 hours of planned sleep opportunity.

Better inputs

Useful tips

Base fluid loss on a measured pre/post activity protocol when appropriate.
Separate planned sleep opportunity from actual sleep obtained.
Adjust food and movement choices for tolerance and professional advice.

Before relying on the result

Limitations and common mistakes

Recovery needs vary with heat, illness, injury, medical conditions, medications, and gastrointestinal tolerance.
The calculator does not diagnose dehydration, heat illness, injury, or readiness to train.
Entered multipliers are planning assumptions and clinician advice takes priority.

Reference

Key terms

Replacement factor: Entered multiplier applied to estimated fluid loss.
Nutrition multiplier: Entered grams-per-kilogram value applied to body mass.
Sleep opportunity: Planned time available for sleep, not measured sleep quality.
Easy movement: Entered low-intensity movement minutes, without prescribed intensity.

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

Is the fluid result a drinking schedule?

No. It is the entered loss multiplied by the entered replacement factor.

Why are carbohydrate and protein separate?

They use different entered g/kg multipliers and serve different planning purposes.

Does planned sleep equal recovery?

No. It is only sleep opportunity and does not measure recovery quality.

When should medical advice override the page?

Symptoms, heat illness, injury, medical conditions, or clinician guidance always take priority.
