Where Sebastien was, leg by leg

Overall position in the race at the mat that closes each leg.

Faster than the median everywhere: the closest margin was on T2 (bike → run).

Race position at every mat

Mats are evenly spaced, not placed by distance — most course distances on this event are interpolated.

“Top %” = segment rank as a share of athletes timed on that segment. km/h is shown only where both ends of the segment sit at a measured distance.

“Segment winner” = fastest athlete on that segment, field-wide. Rows with no result for this athlete (missed mat) are omitted here — the table above says why.

≈ = interpolated course km. The timing provider publishes no distances. Five checkpoints per race are pinned from the split tables (they expose km/h alongside the time); the rest are interpolated between them and are marked ≈. Speeds are only shown where both ends of a segment are pinned — one interpolated span on the long course (Le Périer → Col d’Ornon) is known to be several km too long, which would credit the leaders with 50 km/h up to a col.
