Irwin voluntarily organised over 20 events, involving over 450 athletes aged from under 11 to over 65. His innovations included virtual races and "prediction runs" where competitors guessed their time.
Irwin's events were opened to friends and family and his meticulous handicap encouraged everyone to have a go. A covid-compliance champion, Irwin completed risk assessments and collated declarations, helping with technology so athletes did not miss out.
When permitted, Irwin organised covid-secure, socially distanced races including 800m, 5km, and cross-country. Twice a week he supported group training evenings.
Thanks to Irwin, the club maintained friendly competition, social interaction and health and fitness.
