As of now (early access, not everything in place, etc) game speed is fix to 'normal' as of reserarch and such, but early game you move usually 2-4 tiles/turn (2 if movement in difficult terrain, 4 for easy terrain), in midgame (about turn 60+) if you choose even the right research-perk you can move usually 8-10 tiles even on difficult terrain.

Don't know how you play first EL, but even in EL you could do that. If otherwise you don't choose your path wisely it could be a pain to do things, they're always a game of minmaxing and exploiting race bonuses and such.

Even ES2 if you play well you can end even in turn 100, if you play bad you can still move like a snail even on the 150th turn.

if you pick Necro, you have the skill to teleport between nests.
But you play on large map and 6 players, don't expect to rush everyone on turn 80
