Tighten the router so race-specific reasoning in the general docs points to the matching demand profile instead of speaking in a road/TT-default voice: - periodization.md: anchor the build phase's 'race-specific top-end' to the matching demand doc (tt / road-racing / mtb-xco). - durability.md: show how fatigue resistance manifests per discipline. - data-confounds.md: extend the intermittent-HR caveat to road racing/crits; note TT as the steadier exception where HR is more usable. - strength-for-cyclists.md: link the explosive/sprint transfer to road-racing and sustained-power transfer to TT. - vo2max-intervals.md: match rep length to event (short=surges/road+MTB, long=sustained/TT); extend the HR caveat to road racing. All internal links verified resolving. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TqrhBhC3GEcKyaw8RTk8G6

# Periodization, distribution & taper
|
||
|
||
**Load this doc when:** structuring a season, choosing an intensity distribution, setting a CTL
|
||
ramp, or planning an A-race taper.
|
||
|
||
**Data/knowledge split:** MCP supplies CTL / ATL / TSB, the load ramp, and TSS. This doc supplies
|
||
the logic for *how fast to ramp*, *how to distribute intensity*, and *what TSB to target*.
|
||
|
||
---
|
||
|
||
## Distribution is a principle, not a recipe
|
||
|
||
Do not treat polarized (or pyramidal) training as a fixed formula. The right distribution is
|
||
**context-dependent** — set by training age, weekly volume, life stress, and the current phase.
|
||
|
||
The framing to internalize: effective endurance training is **"the long game, not epic workouts."**
|
||
HIIT should not be prescribed as an acute-response "maximization problem"; what matters is the
|
||
**long-term integration** of intensity, duration, and **frequency**, adapted to the athlete's
|
||
context (Seiler 2024, *Appl Physiol Nutr Metab* 49(11):1585–1599; PMID 39079169;
|
||
DOI 10.1139/apnm-2024-0012 — a peer-reviewed Perspective, open access).
|
||
|
||
**On "frequency matters more than the exact distribution":** this is a reasonable working heuristic
|
||
consistent with Seiler's long-game argument, but note the honest state of evidence — a 2025 review
|
||
of training-intensity-distribution models concludes **no single model is universally superior** and
|
||
that model choice must be adapted to sport, phase, and athlete (Sun, Yu et al. 2025, *Front Physiol*
|
||
16:1657892; PMID 41169886; DOI 10.3389/fphys.2025.1657892). Treat "get enough quality hard sessions
|
||
in, don't obsess over polarized-vs-pyramidal labels" as a defensible principle, **not** a
|
||
quantified finding.
|
||
|
||
> **Citation honesty note:** a specific "Yu et al. 2025" paper claiming *frequency of hard sessions
|
||
> outweighs distribution* could **not** be located in PubMed. Do not cite one. Ground the point in
|
||
> Seiler 2024 (the long-game argument) and the Sun/Yu 2025 review (no model universally superior).
|
||
> See `citations.md`.
|
||
|
||
## Standard periodization: base → build → peak
|
||
|
||
Work **backward from the A-race** (backward mapping). Each phase sets up the next.
|
||
|
||
**Anchor the plan to the A-race's demand profile** — the "race-specific top-end" of the build phase
|
||
means different things per discipline. Load the matching demand doc before shaping the build:
|
||
`references/tt-demands.md` (sustained solo power, pacing), `references/road-racing-demands.md`
|
||
(repeatable supra-threshold surges + a fatigued sprint), or `references/mtb-xco-demands.md`
|
||
(intermittent, supra-MAP bursts). Don't build a TT engine for a criterium, or vice versa.
|
||
|
||
| Phase | Primary job | Emphasis |
|
||
|---|---|---|
|
||
| **Base** | Raise sustainable CTL, aerobic base, **durability**, and strength capacity | High volume, mostly low intensity, small hard dose kept alive; build heavy strength |
|
||
| **Build** | Sharpen threshold & VO2max; add race-specific top-end; preserve durability & strength | Fewer, sharper hard sessions; strength → maintenance |
|
||
| **Peak/Taper** | Shed fatigue, keep fitness, arrive fresh | Reduce volume, keep some intensity, hit TSB target |
|
||
|
||
Templates: `../assets/plan-template-base.md`, `../assets/plan-template-build.md`.
|
||
|
||
## Mesocycle rhythm
|
||
|
||
| Athlete | Rhythm | Note |
|
||
|---|---|---|
|
||
| Younger / high recoverability | **3:1** (3 load weeks : 1 recovery) | Standard |
|
||
| **Masters / higher life stress** | **2:1** (2 load : 1 recovery) | Favor recovery — masters recover slower; the 2:1 protects adaptation |
|
||
|
||
Recovery weeks ≈ 40–60% of the preceding load week's TSS. These are *adaptation* weeks, not lost
|
||
time — the fitness is expressed during them.
|
||
|
||
## CTL ramp guidance
|
||
|
||
- Ramp **CTL gradually** — a common, conservative guide is **~3–7 CTL points per week** sustained,
|
||
lower for masters or when life stress is high. Faster ramps raise injury/illness/overtraining
|
||
risk without proportional benefit.
|
||
- Read the actual CTL/ATL/TSB and ramp rate from MCP (`get_athlete_summary`); this doc only tells
|
||
you whether the ramp is sane. A runaway ramp with a deeply negative TSB trend is a flag — cross-
|
||
check wellness before pushing (`data-confounds.md`).
|
||
|
||
> ⚠️ **The CTL ramp numbers are heuristics, not laws.** Individual tolerance varies widely —
|
||
> **track response** (wellness, performance, durability) rather than forcing a fixed points/week.
|
||
|
||
## A-race taper & TSB targets
|
||
|
||
- **Goal:** arrive with fitness intact and fatigue gone — a **positive but not deeply detrained
|
||
TSB**. A common target window is **TSB ≈ +5 to +15** on race day (higher for shorter/punchier
|
||
events where freshness dominates; lower for long events where fitness retention matters more).
|
||
- **How:** cut **volume** substantially over the final 1–2 weeks while **keeping some intensity**
|
||
(short race-specific efforts) so you sharpen rather than go flat. Don't cut intensity to zero.
|
||
- **Durability caveat:** durability decays if load drops too far for too long (`durability.md`). For
|
||
long/marathon events, taper less aggressively than for short punchy events, or you arrive fresh
|
||
but unable to hold late-race power.
|
||
- Read TSB from MCP and steer it into the target window; this doc sets the target, MCP measures it.
|
||
|
||
> ⚠️ **Taper TSB targets are individual.** The +5 to +15 window is a starting point; some riders
|
||
> peak flat at +5, others need +15–20. **Track how the athlete has raced at known TSB values** and
|
||
> personalize.
