The 2020 Star Wars Rival Run race series was the first runDisney event to succumb to the COVID-19 pandemic. The race was fully cancelled, the only runDisney event to be completely wiped off the map.
Wine & Dine 2020, Marathon Weekend 2021, Princess 2021, and Star Wars 2021 all were offered as virtual-only events (Star Wars was initially offered as in-person before being transitioned to virtual. I am not sure if this was also the case for the other race weekends). Eventually the Wine & Dine 2021 race weekend marked the return to in-person racing at Walt Disney World.
When Star Wars 2021 was transitioned to a virtual event, runDisney announced it would be the last Rival Run event, with the springtime race weekend to be reimagined with new theming. At first, many hoped for a different Star Wars themed weekend. But it was eventually revealed that the spring race event put on by runDisney would be something altogether different: the Springtime Surprise race weekend.
The theming for each race would call back to now-defunct events previously held at Walt Disney World.
The Expedition Everest scavenger hunt and 5K race would take place on Thursday night at Animal Kingdom. If I heard correctly, this was the first nighttime race at Walt Disney World since 2015.
The Race for the Taste 10K would take place on Saturday morning. This foodie-themed race came before the Wine & Dine weekend we know today.
The Tower of Terror 10-Miler would return as a daytime race, taking place on Sunday morning. This popular race used to take place at night.
Runners who completed all three races would also earn a challenge medal.
