Distance might be similar but the spread out concepts are quite different. 2026 has two main, distinctive clusters which are kinda compact on their own: big stadium and all main ice arenas in one; curling&sliding center in the other (+ all the mountaineering sites which orbit around those two).
This preparatory bid by the Swiss brings the spread on another -more dliuted- level. Kinda similar to the Nice-AF 2030.
