Start with the closest real-world task, then use the mapped tools inside each guide.
Marathon training plan workflow with weekly mileage progression, pace zone calculations, long run scheduling, taper timing, and race-day fueling strategies.
Cycling training and route planning guide with power zone calculations, cadence targets, gear ratios, elevation gain estimates, and endurance ride scheduling.
Swimming training workflow with pace calculations, interval set planning, stroke efficiency drills, weekly volume targets, and open-water preparation.
Filter and categorize specialized tools in this niche field by functionality and complexity.
Calculate adult BMI from metric or imperial height and weight. See CDC screening categories, formula steps, and limitations without treating BMI as a diagnosis.
Calculate average pace per kilometer and mile plus speed from one entered distance and elapsed time. Transparent constant-pace arithmetic, not a race predictor.
Calculate a user-entered heart-rate-reserve percentage range with the Tanaka age-estimated maximum. Shows formula and limits; never prescribes training zones.
Reproduce mean kilometre/mile pace and speed from one completed source-owned race result and retained event distance, with an optional same-result displayed-pace comparison—without creating targets, splits, predictions or training advice.
Compare adult BMR equations and a selected activity-multiplier TDEE scenario without generating calorie, macro, or meal prescriptions.
Convert a user-selected energy total and carbohydrate, protein, and fat percentages into calories and grams with adult AMDR context.
Reconcile one completed conventional bicycle gear-pair record from whole tooth counts, measured loaded wheel rollout, and installed crank length.
Reconcile one completed bicycle cadence-speed interval from whole-tooth gearing, measured loaded rollout, recorded speed, and observed distance/time.
Reconcile pace per 100 for one completed, source-labelled swim distance and elapsed-time record without converting course performance or prescribing training.
Reproduce and reconcile the two-point critical swim speed calculation from one source-labelled completed 200 m and 400 m record without prescribing training.
Reconcile a source-labelled swim timing schedule, including every full checkpoint and any final remainder segment, without prescribing race or training pace.
Reconcile one completed adult swimming record with an exact 2024 Compendium code, standard-MET arithmetic, and an independent kcal estimate.
Reconcile a source-labelled latitude/longitude endpoint pair on WGS 84 or GRS 80 with an independent ellipsoidal distance without claiming a route, track, course or swim.
