Alpe spinner with bad connection?

Sometimes I ride with a friend in his garage which has really unreliable Wi-Fi coverage. The game frequently drops in and out of offline mode where other riders in the world disappear. While this isn’t a problem, in wondered if the alpe spinner works if we are offline at the time we cross it? Some things don’t work well with the flaky connection like events and things so I wondered if we could tackle the alpe route without missing the prize if we don’t have a solid signal.
