Really sorry to hear this. I was an avid RunDisney race runner from 2006 - 2012, I’m up relatively high on the mileage chart amongst users here. I remember back in those days the races wouldn’t sell out for months, hard to believe that they sell out in an hour or less now.
I’m excited to finally run again this coming year, thankful that I was able to get a number in about 35 minutes but don’t know what my magic formula was to get it.
Since both Platinum & Gold Club members have guaranteed bibs with their membership - 2 races for Platinum and 1 race for Gold - that means the number of bibs available for open registration has been reduced.
With the old early registration for APs and DVC members, bibs weren't guaranteed, a limited number were available for early registration. Sometimes I had to wait until general registration to pick up the remaining race I wanted.
The introduction of Club runDisney changed everything regarding race registration.
