Advice on map run

Hi,

I’ll be in London for work, and I need to do a training run on one of the days I’m there; I created this map. https://www.strava.com/routes/3327988429394644784

Basically, I’m on Poland Street, and I want to go around the parks to make it more interesting. This will be a 7 am run before the shops open. But I’m wondering if going down Oxford Street on the way back is the best option.

Any suggestions are greatly appreciated!

Cheers
