I'm wondering if the virtual 5K summer series will happen this year. In years past, the virtual summer series medals were previously announced before marathon weekend. While marathon weekend went virtual this year, there has been no announcement whatsoever about the virtual summer series for 2021.
I have done a few virtual races through runDisney. Namely the 2018-2020 Star Wars Virtual Half Marathons, the 2018-2020 virtual summer series 5K races, and most recently the 2021 Walt Disney World Virtual 5K, Virtual Marathon (I chose 26.2 over 6 days to reduce injury risk), the
Castaway Cay Virtual 5K, with the Princess Virtual 10K and Half coming this month and the Star Wars races in April or possibly May since they're virtual.
Except for the 2020 Star Wars Virtual Half, none of the previous Star Wars Virtual Half Marathons sold out. And in fact 2020 did not sell out until after a week or two after they announced the cancellation of the 2020 Star Wars race weekend. The summer virtual series have been interesting. In 2018, one race sold out, but others did not. In fact, I was able to register my nephew for one of the races in late July when the medal was known. The 2019 series themed to Marvel's Avengers sold out entirely, but even then did not do so until a couple of weeks after Avengers Endgame was released. The 2020 races sold out in less than an hour, but that is likely due to limited medal stock because of the pandemic.
I had no plans to run the 2020 Wine & Dine Half, Marathon weekend 2021, and Princess 2021. However, after a good experience running a virtual race in September, I immediately looked into the then known to be virtual 2020 Wine & Dine Half. I decided against it because the medals did not intrigue me enough to pay that price. Wine & Dine was announced as going completely virtual in July or August. As of early September, it had not sold out. I registered immediately for Princess Virtual and Marathon weekend Virtual in September with no issues at all. While both races eventually sold out, they did not sell out for a few weeks. I was already registered for Star Wars when it went virtual and chose to keep my registrations. However, the available registrations did last at least a month. I registered my nephews for the virtual kids races and my little sister registered for the regular virtual half (Yoda and Darth Vader on the medal) a few days after the Death Star medal (original always intended to be virtual race) was revealed. At that time in mid January, most of the races were already sold out, but not all. So they also lasted a couple of weeks.
Are they worth it? That depends on your perspective. As a factor to provide additional motivation to get out there and run, they can be excellent. But just because you sign up for one does not mean that you will automatically put in the work. That depends on you. I chose to register for the virtual 5K, marathon, and Castaway Cay 5K because I really liked the medals. I passed on Goofy and Dopey because I did not want to feel like I had to do those respective distances in consecutive days. Likewise, I chose my Princess races based on how much I loved the movies used this year. I skipped the challenge because I wanted to give myself the choice to not run 6.2 and 13.1 on consecutive days if I did not feel like it. I know that runDisney would send it to me no matter what, but that's my take.
I planned to at least attempt the virtual marathon, but after training and the pandemic did not see eye to eye, I chose to adjust my expectations and go for 26.2 over 6 days. It still worked for me because the motivation did help. I may not have gone 26.2 in one day like I did live in Walt Disney World in 2019 and 2020, but my January 2021 miles were my highest number since December 2020, when I was training for Dopey. So for me the motivation worked. And I do not know if I would have kept it going had I not been signed up for Princess Virtual.
As noted earlier, I kept my originally planned Star Wars races (10K/Half Challenge and Kessel). I did not go for the virtual 5K because the medal does not appeal to me.
