I'm riding with the main group until I get dropped. Which is usually somewhere north on keele but before it turns east to the midway stop at the deli shop. You should be able to keep up until hopefully the group initially turns keele (at which point it goes from a slow pace to hyper speed).

Where was that route map again?

I join the ride where it goes through Yonge/Steels because I live so far north :/
