Formula, assumptions, and example
Formula: Peak week = current weekly hours × (1 + progression rate)^build weeks. Taper target = peak week × (1 − taper reduction). Build total uses a geometric sum; taper total uses the average of peak and target weeks.
This is a transparent planning worksheet for workload arithmetic. It does not decide how hours should be divided among swim, bike, run, intensity, strength, rest, or recovery, and it does not prescribe a safe plan for a particular athlete.
- Current weekly training is a recent representative average, not a one-off maximum.
- Progression is applied once per build week using geometric growth.
- The taper is represented by a straight-line average from peak to target week.
- Sessions per week divides hours evenly only for a rough per-session screen.
- No intensity, sport distribution, injury history, sleep, age, life stress, or recovery data are modelled.
- A zero-week build or taper is permitted and has a clearly defined total.
- The output is planning arithmetic, not medical advice or a coach's individualized prescription.
Worked example: A 10-hour base with 5% weekly growth reaches about 12.16 hours at peak; a 30% two-week taper target is about 8.51 hours.

How to use the Triathlon Training-Load Planner for a real question
Project weekly training hours through a build and taper using explicit progression, reduction, and session-count inputs, with a transparent workload summary. Start with one clearly defined goal, enter values in the units shown, and keep the result attached to the assumptions below.
What this answers
This tool is useful when your question includes triathlon training plan calculator, weekly training hours, triathlon taper calculator. It returns the outputs declared in the calculator contract rather than a live quote, approval, diagnosis, or professional sign-off.
What you enter
Current weekly training · Build weeks · Weekly progression · Taper weeks · Taper reduction · Sessions per week. Keep the same time period, unit system, and currency wherever the form requires comparable values.
How to check it
Run the worked example first, compare its output with the page's example, then change one input at a time. This makes an unexpected result easier to trace to a unit, boundary, or assumption.
Three checks before you rely on the answer
- Match the question. Confirm that the result means the quantity you need, not a similar-sounding percentage, balance, rate, or estimate.
- Match the inputs. Use the requested units and period, and read each hint before replacing the example values with your own.
- Read the boundary. Review the assumptions and limits. Current weekly training is a recent representative average, not a one-off maximum.

Context and background
Why sports rates need definitions
A sports percentage or rate depends on attempts, outs, minutes, shots, or another denominator. Matching that definition is necessary before comparing players, teams, or seasons.
Box-score analysis became more useful as raw events were expressed as rates that account for opportunities. These tools show the denominator so the result remains tied to the supplied record.
Research and review
How this guide was researched
Researched by Hassan ALRowaie, Founder and editorial researcher at WorldCalculate.
This guide follows the live calculator's declared inputs, formula, worked example, assumptions, validation boundaries, and source-backed methodology. The review date describes editorial review of the calculator explanation; it is not a promise that external facts or rates remain current.
Training plans fail when a weekly number is treated as a complete coaching prescription. This planner keeps the arithmetic narrow: it projects a workload path from explicit inputs, then leaves sport balance, intensity, recovery, and personal safety to the athlete and qualified support.
What this planner calculates
The page takes a current weekly-hour baseline, applies a repeated percentage progression for a build phase, and then applies a reduction for a taper phase. It returns peak, totals, and rough per-session screens.
It does not create daily swim, bike, or run workouts. A workload total is a planning quantity, not a complete training plan.
Geometric build growth
Each build week is the previous week multiplied by one plus the entered progression percentage. This makes the peak week a geometric rather than linear projection.
The build total adds each week in that sequence. When progression is zero, the calculation correctly becomes current weekly hours multiplied by the number of build weeks.
Taper calculation
The taper target is peak weekly hours multiplied by one minus the taper reduction percentage. The displayed taper total uses the average of peak and target multiplied by taper weeks.
A real taper may change volume, intensity, frequency, and sport distribution in ways this simple line cannot express. The result is therefore a scenario screen, not an instruction to follow blindly.
Per-session screen
Peak and taper per-session values divide the weekly total by the entered session count. This is a rough equal-share view and should not be mistaken for a recommendation that every session have equal duration.
Triathlon training often includes different session purposes and recovery needs. Use the screen to spot scale, then distribute the work deliberately.
Worked example
Starting at 10 hours per week and progressing 5% for four build weeks gives a peak of 10 × 1.05^4, or about 12.16 hours.
With a 30% taper reduction, the target is about 8.51 hours. The planner also reports the geometric build total and the average-based taper total so the block's scale is visible.
What the model omits
The arithmetic does not know whether the workload is mostly easy aerobic work or high intensity. It also omits strength training, rest days, sleep, illness, injury, work, family demands, climate, altitude, and equipment.
Those omissions are not small details. They are why a generic percentage should be treated as an exploratory scenario and reviewed with context.
Safety and adjustment
Pain, unusual fatigue, illness, dizziness, chest symptoms, or worsening recovery are reasons to stop and seek appropriate medical or coaching advice rather than increase the next percentage.
Adjust a plan when the real week differs from the scenario. A missed session should not automatically be repaid by stacking unsafe hours into another day.
FAQs
Does five sessions mean five equal workouts? No. It only divides the weekly total for a rough screen; actual sessions can have different durations and purposes.
Can I set taper weeks to zero? Yes. The page then leaves the peak week unchanged and reports no taper-phase total, which is explicit rather than silently inventing a taper.

Enter Current weekly training, Build weeks, Weekly progression, Taper weeks, Taper reduction, Sessions per week, then choose Calculate.
What are the limits of this calculator?
Current weekly training is a recent representative average, not a one-off maximum. Progression is applied once per build week using geometric growth. The taper is represented by a straight-line average from peak to target week. Sessions per week divides hours evenly only for a rough per-session screen. No intensity, sport distribution, injury history, sleep, age, life stress, or recovery data are modelled. A zero-week build or taper is permitted and has a clearly defined total.
