Each site is discounted by how substitutable its activity is for a gym and how far its price tier sits from a mid-market club — so 0 gym floors and 0 other sports sites weigh 0, not 0.

Competition since opening — gyms within 1 km, by the year they opened

1 when it opened, 2025-04-01 → 1 today, 0 arrived since

1 rival(s) within 1 km when this club opened, 1 now. The forecast uses the founding count: it measured better than averaging the field over the club's life (LOOCV 0.091 vs 0.106).

Access — straight-line distance, GTFS

Nearest rail: Champagné — 13034 m
Nearest bus: École — 1980 m
Counted footfall: Champagné — 13034 m, 13,965 travellers a year (SNCF)

Straight-line, not travel time: no free routing service covers France at this volume, so a stop 300 m away across a railway line reads the same as one 300 m along the street.

Catchment — INSEE 200 m population grid, Filosofi 2021

Ring	Residents	Per km²	Median age	Adults 18–64	Share of residents

2.0 km	556	44	41.6	336	60%
3.0 km	1,322	47	44	794	60%

Adults 18–64 is the span members come from. A median age alone does not separate a student quarter from a family suburb, and those are not the same market.

Published at commune level (IRIS 722310000). An IRIS is a neighbourhood of roughly 2,000 people; a commune can be a whole town. The level travels with the figure, so a town's median is never read as this street's.

Officers — company representatives on file

Martine ROUSSEAU (BLANCHET) (officer)

Legal representatives, not shareholders. France closed public access to the beneficial-ownership registry in July 2024, so who owns the company is not obtainable from open data.

Filed accounts — INPI, the keyed annual accounts

Revenue: not filed
Net result: not filed

No keyed accounts in INPI's feed for this company. Absence means unfiled, not zero — most small French companies file late or not at all.

Legal filings — BODACC, the official French business gazette

2025-04-08: Créations (Avis initial)
2024-01-19: Radiations (Avis initial)

Newest first. Accounts filed on time are the ordinary case; an insolvency, a receivership or a pledge over the business would appear here too, and none does unless it is listed above.

What this is. The Location Score is model output, computed from open data; it is not a measured fact and not a valuation. Registry facts — name, SIRET, NAF, address, opening date, officers, filed revenue — come from INSEE Sirene and the Ministère des Sports facility census. Population, age profile and income are INSEE (Filosofi 2021, 200 m grid and IRIS). Competitors are the active, genuinely-operating gym floors in this database. Distances are straight-line, not travel time.
