Strengths & weaknesses — by weighted effect

▲ Saturation 100 — 4 clubs / 36,130 residents = 11.07 per 100k against 11.01 nationally
▲ Capture 82 — 1,801 residents + 1,547 workers, demand within 500 m against every competitor within 3 km
▲ Competition 74 — 0 genuine gym floors and 0 other sports sites within 500 m, weighted by substitutability and price tier
▼ Income 18 — 18,740 EUR against 22,380 nationally, containing IRIS (no IRIS centre inside the radius)

Each parameter scores 0–100 on a stated line between named breakpoints, then the seven combine on their weights — renormalised over whatever was measurable, so a missing parameter dilutes nothing rather than counting as zero.

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 7 gym floors and 3 other sports sites weigh 6.3, not 10.

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

6 when it opened, 2026-07-01 → 6 today, 0 arrived since
6 rival(s) within 1 km when this club opened, 6 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). 2 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest rail
Roanne — 820 m
Nearest bus
Roanne St Louis — 145 m
Counted footfall
Roanne — 820 m, 1,092,027 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.

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.

Officers — company representatives on file

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.
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.
