Are you gracing SWOT with a presidential visit?
Is there an event on? Probably should have checked that (I know there’s one in Albany).
Event or is your friend 4:00pm if you are passing on the way back to the city
The Colour Patch next to where you would have been watching the parasailers is probably the best coffee spot, but yes, there isn't much choice for an evening meal. Don't know why, but there's an invisible barrier which decent food and coffee can't penetrate about 10km South of Margaret River. By the way, a former OA President had a holiday home at Augusta, just off Caves Road.
Bunbury Parkrun is at Big Swamp, slightly inland from your route. I think SWOT prefers the
Bunbury Runners Club, an institution which has been around since decades before Parkrun. There are some good running routes on their website, and it looks like their Saturday run starts from a cafe just off the main shopping drag.
Oh well, opportunity missed (but I think the run I actually did this morning was worth it).
I know JillE does parkrun down there.
