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 12 gym floors and 19 other sports sites weigh 13.8, not 31.

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

3 when it opened, 2026-08-31 → 3 today, 0 arrived since
3 rival(s) within 1 km when this club opened, 3 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). 4 nearby site(s) have no usable opening date and are not in either count.

Access — straight-line distance, GTFS

Nearest tram
Université — 934 m
Nearest bus
Gay Lussac — 129 m
Counted footfall
Brest — 2427 m, 2,777,923 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.

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.
