Castles has worn plenty of other hats during lockdown, being an important member of the racing sub-committee that helped steer the industry back to racing, the sort of hands-on work that means many hours on the phone and not a lot of thanks.
He gets the reward of a cracking race meeting today whereas one of the other key industry drivers during lockdown has been trainer Tony Pike, who could get more tangible rewards.
As president of the Trainers' Association, Pike has been a vital link to the likes of RITA during the craziness of Covid-19 and has not been scared to stand his ground on the important issues, all while trying to run his own huge stable.
While today won't be easy shopping for punters, Pike looks to have at least three good chances, headed by Cyber Attack in race 10. He was an impressive recent trial winner here and loves Te Rapa, having once beaten superstar mare Verry Elleegant here as a two-year-old.
"He is forward enough to win and has a good draw so he is probably my best of the day," says Pike. "But I also rate Hot Spring Project [race six] and Universal Stars [race five] as hard to beat and the team are ready to go."
Te Rapa starts earlier than usual at 10.30am with Awapuni also racing today, with their first race at 11.13am.
