Altitude weather delta
High 2,436 m minus low 7 m is 2,429 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 15.8 °C cooler at the high point than the valley, all else equal.
That is a model (International Standard Atmosphere environmental lapse), not a forecast and not a trail-closure. Wind, snow, and storms stay in Hazards.

Ingested from OpenStreetMap relation 7411272 (ODbL). The mapped line and 2D length are derived from that geometry. Ascent, descent, and high/low points await Copernicus GLO-30 (pending:copernicus-dem) on this first pass — the line is ~926 km. Water, permits, and hazards were not taken from OSM tags and must be verified.
OSM 2D length is 925.9 km (relation 7411272; superroute La traversée des Pyrénées, ref=GR 10, Wikidata Q1486783; numbered sections 1–9 stitched; sec.6/sec.9 variantes and an unnamed child omitted). Published ~866 km / ~50+ days (https://www.ffrandonnee.fr/randonner/sentiers/gr-10-la-grande-traversee-des-pyrenees, checked 2026-08-25) are cross-checks only, not this DataPoint. The line is point-to-point: Hendaye (OSM start) to Banyuls-sur-Mer (OSM end).
typicalDays 50 is the published typical window (~50+ days on the FFRP page, checked 2026-08-25), not Math.round(lengthKm/12). Not a DataPoint. High-section season is commonly Jun–Sep; that stamp is not this field (bestSeason left unverified).
Water was not mapped to named WaterSource points (no honest atFraction). Villages, gîtes, and streams exist; they were not positioned from an official named list this pass.

Hazards
- Alpine weather on the high Pyrenean sections: storms, snow out of season, and long days between villages (https://www.ffrandonnee.fr/randonner/sentiers/gr-10-la-grande-traversee-des-pyrenees, checked 2026-08-25).
- Length: a thru-hike is weeks, not a weekend. Logistics (gîtes, refuges, resupply) fail more often than the walking grade (same page, checked 2026-08-25).
