Welcome to OpenStreetMap and thanks for adding your store.

Rather than using shop=running_store, which isn't documented or used in the UK, you might be better off using shop=sports with any additional tags which apply. The documentation for this tag is at https://wiki.openstreetmap.org/wiki/Tag:shop%3Dsports

It's entirely up to you, so feel free to ignore my suggestion.

I've tweaked your opening hours to use the syntax expected by OSM's data consumers.
