You're also not going through De Beauvoir. So you will be doubly fine.
This is a pretty simple walk. It will be a bit congested around Islington probably. I would mix it up by stopping at a couple of pubs (Dove in Broadway Market maybe? Royal Inn on Viccy Park? Wenclock? Look Mum? Orwell up on Essex Road [this would radically change your route]).
