TFL Guided rides into London

[mr_cellophane]

Just seen TFL are doing guided rides in to encourage people to cycle to work.

Can someone explain the route for the Finsbury Park ride
here at Drayton Park. Why the big detour. It doesn't look necessary in Street View.

1 way street. It would be better to come off Drayton park 1 turn earlier and head straight down Arvon road.

Edit: sorry it's not 1 way, google maps say's it is, but when looking at street view it isn't. The new road layout obviously hasn't been updated on google and thus it doesn't work out that as a cyclist you can go down there. Not that google does routes for cyclists.
