The Walter stable has been a big supporter of Canberra Racing, but Friday's meet will be the last time it is represented at Thoroughbred Park.
Canberra Racing chief executive Peter Stubbs was confident the scheduled eight races would go ahead despite wet weather shutting down the ACT's sports grounds on Wednesday.
But it will probably be a wet track, listed as a heavy 8 on Wednesday after the deluge.
Guy Walter won this year's $200,000 Canberra Cup (2000 metres) with Jacquinot Bay and was fourth on Canberra's training premiership with 11 winners when he died of a heart attack a month ago.
His wife Wendy took over the stables, but has decided she'll give the game away on Saturday week, the day before Thoroughbred Park's next race day.
She has just one runner on Friday, Doubos in the maiden plate for fillies and mares (1200m).
"There's no problems for Friday. There's no surface water on the track today," Stubbs said on Wednesday.
"It's a heavy 8 at the moment, whether that improves is [unknown], but that's a possibility with the forecast that we've got for today, tomorrow and Friday."
