Race-Week Taper Planner
Build a race-week taper using the Bosquet 2007 meta-analysis: 41–60% volume reduction over 8–14 days while keeping intensity sharp.
Result
Weekly volume through the taper
From your peak week to race week.
Week by week
2 weeks out
44.8 km (44% under peak) · longest run 20.2 km · 3 quality sessions
Keep the pace of quality sessions and the number of runs; shorten the reps, easy runs and long run.
Race week
27.2 km (66% under peak) · longest run 12.2 km · 2 quality sessions
Race week: every usual run, all short, with a few race-pace strides; nothing new, sleep and carbs first.
The formula, worked through
- Formula Race-Week Taper Formula + Carb Loading (Burke)
Race-week taper formula: cut volume 41–60% over about 2 weeks while holding intensity and frequency (Bosquet 2007); performance usually improves about 3%.

Use it from an agent or code
Any agent can run this calculator by URL: put the inputs in the query string and get JSON back, with the inputs that used defaults and a line to cite (add format=md for markdown). MCP clients reach it through https://aifithub.io/mcp.
In code, import the same module; it runs where you import it, with no request or key.
import { compute } from "https://aifithub.io/engines/race-week-taper.js"; Input and output contract, TypeScript types and the guide for agents.
