Riga - Walk from Central Market to Freedom Monument?

[NickAndysMom]

When we are in Riga this summer, we plan to walk from Central Market to Freedom Monument. Google Maps plots our course northeast along Satekles iela, then along the north east side of the park on Raina bluvaris, past the university.

 

I'm wondering, are these good walking streets? It looks like they might be rather busy. Would it make more sense for us to go back through Old Town, by instead leaving the Market heading southwest toward the river?

 

I know this is a pretty technical question! Hoping someone who lives or has spent a lot of time in Riga might be able to point me in the right direction.
