Congratulations, and yes, that jump from “one-off run” to “annual tradition” is a real leadership shift. I helped with a charity quiz night that grew the same way; by year three, I was drowning in spreadsheets until a friend took over registrations and another handled sponsors. The event got better because I stopped being the bottleneck. Before chasing books or courses, build a small core team: one person for registrations, one for volunteers, one for sponsors, and one for race-day logistics. Give each a clear outcome and deadline, then let them own it. A simple shared checklist and a post-event debrief will teach you more than most courses.
