10k running route near Asakusa

Hi people,

I'm going to be over in Tokyo in November and will be staying in Asakusa.

I was wondering if anyone would have any advice for mapping out a 10k route locally?

I guess the obvious option would be to hit Sumida-gawa, but then would I better following it north or south? Ideally, I'd like to avoid roads as much as possible and be away from street level so I'm not bothering people walking about. The Northern route seems more to fit that route (assuming I start at Asakusa station), but for people who know the area, what would you say?

Alternatively, is Ueno Park my best bet?

Also, if anybody has any recommendations for a good route that's easily accessible from Asakusa, I'd be all ears.

As an aside, I was thinking about doing a parkrun, but they all seem relatively remote from Asakusa. Are there any similar type events closer to central Tokyo? (I don't want to be boarding trains dripping in sweat).

Thanks in advance!
