Climbing totals signal a physically demanding route for riders
Viewed through climbing, 53,450 metres over 3,479 kilometres averages roughly 15 metres of ascent per kilometre. This figure frames the route's physical demands as a central feature of the announcement.
Stage categories show a route spread across varied terrain types
Through the stage mix, eight hilly stages outnumber the five mountain and six flat stages, while two time trials add individual-effort racing. The distribution suggests the route draws on several terrain types rather than concentrating on one profile.
