Grey Cup fan march - do they walk the entire way?

I noticed that again the CFL has a Grey Cup fan march. I see the route was downtown Winnipeg to the stadium. Do they really walk the entire way? That is a long way and would have taken hours.

I can't see people wanting to do that. Is there a shuttle bus for those who cant continue? Want to try it at the next Grey Cup which i'm sure wouldn't be as long as this past route.
