Hmmm.
How large is Hogwarts? It’s non-Euclidean, but it’s Euclidean enough for Quirrel to shortcut by blowing up walls in a quasi-straight line.
Given Quirrel’s rarely used but significant ability to blow stuff up, I think that once he reached steady state he could blow up several cubic meters of masonry per second for a good few meters per second rate of travel.

Alternatively, Quirrel’s Potterdar gives him a direction sense that follows a geodesic.
