Grand Tour Time Map
Where a Grand Tour is won and lost, stage by stage. Every rider's time after every stage of the Tour, Giro, Vuelta and Tour de France Femmes since 2016, from the official timing books.
Compare editions
Set up to four editions of any race side by side — including announced 2027 routes. The first slot follows whichever edition you pick above; change the others freely.

Click any stage block to open that stage. A bunch sprint is 15+ riders on the winner's time; solo means the winner was at least 3 seconds clear; from the break counts stage wins by a rider who started the day outside the top 20 overall.
How the race was built
The shape of this edition — how much time trialling, how many summit finishes, how many days ended in a bunch sprint — and the same for every other edition of the race.
A bunch sprint is a stage where 15 or more riders finished on the winner's time; a reduced sprint 4–14; solo means the winner was at least 3 seconds clear. From the break counts stage wins by a rider who started the day outside the top 20 overall. Time-trial distances are the official stage distances.
The GC story
Gap to the eventual winner after every stage. The strip under the axis shows what kind of stage it was.

Overall after the stage
Where the time went
Pick a rider: time lost (or gained) on each stage against a reference rider — by default the eventual winner. Bars are coloured by stage type.
What decided it
For this edition: the stages where the top ten were pulled furthest apart. Across editions: the share of time differences among the final top ten that was created on each kind of stage.
Decisive stages
Where the race is decided, by edition
Each bar splits the total top-ten time spread created in that edition by the stage type it happened on. Stage types are inferred from the official climb categories: a summit stage finishes on a classified climb of 2nd category or harder.
Iconic climbs, timed
Timed ascents of the famous climbs, by year, from the chronoswatts.com database (Frédéric Portoleau's TV-timed sections with estimated power). These are not official times — the race only times the finish — and the database is a sample, not a complete record: see the note below.
Fastest in the database
By edition
Each point is one rider's timed ascent; the line joins the fastest time of each year. Power is Portoleau's estimate standardised to a 78 kg rider+bike, with his own published thresholds (410 W "suspicious", 430 W "miraculous", 450 W "mutant" for long mountain stages). Coverage is uneven: the database has the 2025 Tour but nothing from 2024 or 2026 and only a handful of ascents from 2017, so a "fastest in the database" is not necessarily the fastest ever — Pogačar's 2024 Plateau de Beille and 2026 Alpe d'Huez ascents, for example, are not in it. It is almost entirely Tour de France (a few Vuelta, no Giro). Treat it as Portoleau's timed sample, not a complete record book.
A rider across editions
Every Grand Tour in the data for one rider: final position, gap, and how that gap split across stage types. "Front of race" counts top-three placings at classified climbs and intermediate sprints away from the finish.
Method
Source: official stage classifications and general classifications published by the race timekeeper for the Tour de France (2016, 2019–26), Vuelta a España (2016, 2019–26), Giro d'Italia (2020–22) and Tour de France Femmes (2022–26). Times after each stage include bonuses and penalties as applied by the commissaires. "Time lost on a stage" is the change in a rider's GC gap to the reference rider from one stage to the next, so it includes bonus seconds. Team time trials appear as a stage but without individual results. Stage types come from the climb categories on the mountains classification sheets (HC/1st category = mountain; a 2nd-category-or-harder finish = summit; smaller climbs = hilly). Neutralised stages and stages where commissaires took times before the finish are shown as published. Riders are matched across editions by name; a handful of name variants may remain split.
