Here are all the options currently on the WA calendar with a 3000m SC excluding other countries' regional or National Championships where he could compete OC:
June 26: Meeting de Blangnac, FRA (F)
June 27-29: Kazakh Athletics Cup, KAZ (F)
June 28-30: Jack Brow Memorial, CAN (F)
June 29: Torneo Invierno Porteño, ITA (F)
June 29: Warszawska Liga Lekkoatletyczna, POL (F)
June 29: MAA Circuit, MRI (F)
June 29: Copa RS de Atletismo, BRA (F)
June 29: Troféu IVOTI de Atletismo, BRA (F)
June 30: Scottish National Athletics League, GBR (F)
So unless they're adding a steeple to Penn or he's going to the Canadian National Champs, the Jack Brow meet looks like the most likely.
