As we announced a while back, Google has decided to end of life their Chrome applications. Races used the RunSignUp.com/CheckIn link to get to this app (or downloaded it as a Chrome app) to get to this version. Effective January 1 it will no longer be available. We are posting the message on the right when you open that page until then.
The web check-in is still a great option for people with laptops and reliable internet access. And we have added an easy way to assign delegate access to just the check-in app. You will also see a redesign of the web check-in page in 2019.
