- [Is TrainingPeaks worth it for a self-coached cyclist?](https://www.adaptcycling.com/guides/is-trainingpeaks-worth-it-self-coached): TrainingPeaks is the gold-standard analysis platform — but for a self-coached rider with no coach, is it worth $20/mo? An honest verdict.
- [TrainingPeaks free vs Premium: what the free tier gives you](https://www.adaptcycling.com/guides/trainingpeaks-free-tier-self-coached): What the free TrainingPeaks Basic tier does for a self-coached cyclist, what it withholds, and whether Premium or a free alternative wins.

- [How to estimate FTP without a power meter](https://www.adaptcycling.com/guides/ftp-without-a-power-meter): Estimating FTP from heart rate, RPE, and Strava when you don't own a power meter — how close you can get and where the method breaks down.
- [20-minute vs 8-minute FTP test: which to use](https://www.adaptcycling.com/guides/ftp-20-min-vs-8-min-test): How the 20-minute and 8-minute FTP tests differ, the multipliers each uses, and which one fits your riding — plus why both are only protocols.
- [Why cycling apps show you different FTP numbers](https://www.adaptcycling.com/guides/why-apps-show-different-ftp): Strava, Xert, Intervals.icu, and TrainingPeaks can each report a different FTP. Why the estimates diverge and which one to trust.
- [Is your ramp test FTP too high? Why it happens](https://www.adaptcycling.com/guides/ramp-test-ftp-too-high): Ramp tests overestimate FTP for anaerobically-gifted riders and underestimate it for diesels. Why the 75% rule misfires and how to correct it.
- [How often should you test your FTP?](https://www.adaptcycling.com/guides/how-often-to-test-ftp): How often to re-test FTP as a self-coached cyclist — twice a year, not every six weeks — and why modeled estimates change the cadence.
- [How long should your taper be? What the evidence shows](https://www.adaptcycling.com/guides/how-long-should-your-taper-be): Three canonical sources give three different volume cuts, and nobody has ever tested a personalized taper against a standard one.
- [Winter cycling training plan: build an indoor season that holds](https://www.adaptcycling.com/guides/winter-cycling-training-plan): How to structure November-to-February training — base vs intensity indoors, how much is enough, and why winter is when plans break.

- [Wahoo SYSTM alternatives for outdoor riders](https://www.adaptcycling.com/guides/wahoo-systm-alternative-outdoor-riders): SYSTM sends real structured workouts outdoors — but the test that personalizes them is indoor-only. What that costs an outdoor rider, and the options.
- [Training apps that don't need Strava: the Wahoo route](https://www.adaptcycling.com/guides/train-without-strava-connect-wahoo): Wahoo's partner matrix has Strava carrying routes, segments and finished rides — but not plans. The direct route, and who already uses it.
- [Wahoo planned workouts not syncing: an ordered diagnosis](https://www.adaptcycling.com/guides/wahoo-planned-workouts-not-syncing): Four unrelated failures wear the same symptom. Wahoo's own troubleshooting order separates them, and it starts with the sync window.
- [Wahoo FTP without Full Frontal: the shorter routes](https://www.adaptcycling.com/guides/wahoo-ftp-without-4dp-test): Wahoo ranks its own alternatives to the hour-long 4DP test: best, better, ok. What each rung measures, and which numbers get estimated.
- [KICKR ERG mode too hard: why it fails at rep five](https://www.adaptcycling.com/guides/kickr-erg-mode-target-too-hard): ERG removes your ability to pace, so a target pitched slightly high fails late rather than early. The lockdown escape, and the three real causes.
- [KICKR CORE 2 Zwift Cog: structured workouts explained](https://www.adaptcycling.com/guides/kickr-core-2-zwift-cog-structured-workouts): The Zwift Cog leaves you one 14-tooth gear. Why ERG mode makes that a non-issue, and where the missing range actually costs you.

- [Karoo structured workouts without TrainingPeaks](https://www.adaptcycling.com/guides/karoo-structured-workouts-without-trainingpeaks): TrainingPeaks is not required, and Hammerhead's own docs are part of why people think it is. The free upload route and the providers that qualify.
- [Training plan apps for the Hammerhead Karoo](https://www.adaptcycling.com/guides/karoo-training-plan-app): Hammerhead ships no training platform, so the app you connect is the plan. What TrainingPeaks, TrainerRoad, Intervals.icu and Xert each actually do.
- [Intervals.icu to Karoo workout sync: how it works](https://www.adaptcycling.com/guides/intervals-icu-karoo-workout-sync): The official sync landed in January 2025 and is created from the Karoo itself. What syncs, what the importer rejects, and the format trap.
- [Karoo workouts not syncing: how to find the real fault](https://www.adaptcycling.com/guides/karoo-workouts-not-syncing): Check the Dashboard first — that one look halves the problem. The provider rules that block a push, the device half, and the failure that is not one.
- [ZWO file not importing to a Karoo: the rejection rules](https://www.adaptcycling.com/guides/zwo-file-not-importing-karoo): Hammerhead rejects the whole file, not the bad step. The step types it accepts, the target rule, and the difference between rejected and ignored.

## Glossary
- [FTP (Functional Threshold Power)](https://www.adaptcycling.com/glossary/ftp): The highest average power you can sustain for approximately one hour. Used to anchor every training zone and workout prescription.
- [TSS (Training Stress Score)](https://www.adaptcycling.com/glossary/tss): A single-ride training-load score that combines duration and intensity. One hour at FTP equals 100 TSS. Used to sum daily and weekly training load.
- [CTL (Chronic Training Load)](https://www.adaptcycling.com/glossary/ctl): A 42-day exponentially-weighted average of daily TSS — the fitness side of the fitness/fatigue model. Rising CTL means you're accumulating fitness.
- [ATL (Acute Training Load)](https://www.adaptcycling.com/glossary/atl): A 7-day exponentially-weighted average of daily TSS — the fatigue side. ATL responds fast; it's why you feel flat after a hard block.
- [TSB (Training Stress Balance)](https://www.adaptcycling.com/glossary/tsb): CTL minus ATL — your 'form.' Negative TSB means freshness-in-debt (high fatigue); positive TSB means you're rested and primed for a race.
- [Intensity Factor (IF)](https://www.adaptcycling.com/glossary/intensity-factor): A ride's normalized power divided by your FTP. IF around 0.90 is a typical sweet-spot effort; IF 1.00 is an hour at FTP.
- [Normalized Power (NP)](https://www.adaptcycling.com/glossary/normalized-power): A power metric weighted to reflect the physiological cost of variable efforts. A surgy crit can have NP well above average power.
- [Sweet Spot training](https://www.adaptcycling.com/glossary/sweet-spot): Sustained efforts at roughly 88–94% of FTP. Produces most of the aerobic adaptations of threshold work with less fatigue — hence 'sweet spot.'
- [Polarized training](https://www.adaptcycling.com/glossary/polarized-training): Distribution where ~80% of training is easy (below the first threshold) and ~20% is genuinely hard (threshold-to-VO2max), with little in the moderate middle. Popularized by Seiler.
- [VO2max](https://www.adaptcycling.com/glossary/vo2max): Maximum rate your body uses oxygen during exercise. Trainable via short intervals (3–8 min) near maximum sustainable aerobic output.
- [Critical Power (CP)](https://www.adaptcycling.com/glossary/critical-power): The highest power sustainable in a metabolic steady state — the asymptote of your power-duration curve. A close physiological cousin of FTP.
- [W' (anaerobic work capacity)](https://www.adaptcycling.com/glossary/w-prime): Your finite work capacity above Critical Power, in kilojoules — the 'battery' you drain on hard efforts and recharge when you ease below CP.
- [Power curve (mean maximal power)](https://www.adaptcycling.com/glossary/power-curve): Your mean maximal power for every duration. Its shape reveals rider type and lets us estimate FTP, CP, and W' without a formal test.
- [Lactate threshold (LT1 & LT2)](https://www.adaptcycling.com/glossary/lactate-threshold): The intensities where blood-lactate behavior shifts — LT1 (aerobic, ~2 mmol/L) and LT2 (anaerobic / MLSS, ~4 mmol/L). FTP is the field proxy for LT2.
- [Zone 2 (aerobic endurance)](https://www.adaptcycling.com/glossary/zone-2): Low-intensity aerobic endurance, roughly 56–75% of FTP and below the first threshold. Conversational riding that builds the aerobic base.
- [Tempo (Zone 3)](https://www.adaptcycling.com/glossary/tempo): Moderate riding at ~76–90% of FTP — 'sustainable but working.' Useful in doses, but the classic grey-zone trap when it becomes your default.
- [Aerobic decoupling (cardiac drift)](https://www.adaptcycling.com/glossary/aerobic-decoupling): Cardiac drift: heart rate climbing relative to power over a long steady effort. Above ~5% (Pw:HR) it flags an aerobic-base or durability limit.
- [Durability (fatigue resistance)](https://www.adaptcycling.com/glossary/durability): Resistance to the late-ride decline in power and efficiency after hours of work — endurance's emerging 'fourth dimension' beyond VO2max.
- [Ramp rate (CTL ramp)](https://www.adaptcycling.com/glossary/ramp-rate): How fast your CTL climbs per week. A sustainable band is roughly 3–8 CTL/week; hold it higher for too long and you risk overreaching.
- [Periodization](https://www.adaptcycling.com/glossary/periodization): Structuring training into phases — base, build, peak, taper — across macro, meso, and microcycles to progress toward a goal event.
- [Taper](https://www.adaptcycling.com/glossary/taper): Progressive pre-event load reduction — cut volume ~40–60%, hold intensity — to shed fatigue while preserving fitness. Worth ~2–3%.
- [Relative Effort (Strava)](https://www.adaptcycling.com/glossary/relative-effort): Strava's HR-based training-load score, successor to the Suffer Score. Because it's heart-rate-based, it's not comparable to power-based TSS.
