Interplanetary 5K Race

Dome Interplanetary 5 K V Wb Rev2

Run the Planets!

Virtual Interplanetary 5K Race + 1 Mile Fitness Walk

UPDATE - January 22, 2021 

The Interplanetary 5K has always been held in March. This has been bad timing for us in 2020 and 2021! Last year, we transferred all folks who had registered for the Interplanetary 5K to 2021, thinking we would certainly be able to race this year. Perhaps in person races can be held this summer (we hope so!) but we do not feel it is a good idea to host an in-person race this March. Therefore, the 2021 Interplanetary 5K will be virtual! - Mike Rucker and Renae Kerrigan

Register by March 1 to guarantee a shirt!
