Lost AirPod

Hello everyone!
I was on my usual morning walk yesterday (Wed 18 November) and have somehow lost 1 AirPod. I know its a long shot but if anyone has spotted it or handed it in anywhere, I'd be most grateful!

My walk through Tabard Gardens, over Long Lane, through Guys Campus, over LB station, down the LB steps at the bridge, along More London, cutting through the path to behind where Cross Town donuts is, under the railway bridge to snowsfields and through leathermarket gardens onto Weston Street.

My music cut along the More London part of the route which makes me think I lost it then (distracted trying to avoid maskless people and didnt notice that may have been what stopped the music!) but could have been anywhere.

I tried 'lost my' on my phone but the airpod needs to be within bluetooth distance.

Any other suggestions on how to find are more than welcome! Thank you!
