The usual way:
Plan something important and time sensitive that requires you to cross university avenue before or just as the ttc starts opens running Sunday morning
Forget about the marathon
Forget about TTC restrictions on Sunday morning
Get on your regular route before having a coffee
Look dazed when the streetcar driver tells you or just implies there is some sort of something going on
Overhear him telling a tourist that _the marathon is on you can’t get there”
Listen to other people swearing
Try and explain what’s going on to people who don’t speak much English (or any other language you have, so you aren’t really all that much help)
Realize a cab through the marathon is going to be outrageously expensive, but seriously consider it anyway.
Get on the subway
Go to a stop you rarely visit and/or that is under construction.
Get instructions that include “see that arrow?” And you see 10 arrows.
Ask 3 more times.
Finally find the hidden hallway you need in the new construction.
Get on streetcar headed west about 30 minutes later than you needed.
