Competitive field — every active gym and other sports site within 3 km

Band	Gym floors	Other sports	MCI weight
within 500 m	1	0	1.00
500 m – 1 km	2	1	2.16
1 – 2 km	5	1	4.40
2 – 3 km	3	2	2.80
Within 3 km	11	4	10.4 total

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 11 gym floors and 4 other sports sites weigh 10.4, not 15.

Other sports sites — 4 within 3 km, discounted by activity

Access — straight-line distance, GTFS

Nearest rail: Saint-Malo — 1427 m
Nearest bus: Arabie — 147 m
Counted footfall: Saint-Malo — 1427 m, 1,832,479 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

3.0 km	38,584	1,365	52.2	20,477	53%

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 iris level (IRIS 352880201). 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.

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.
