Virtual Challenge - If I join late, do previous activities logged during the challenge timeframe count? Q: If I join a challenge after the start date, do my previous activities during the challenge timeframe count? A: Yes - a participant’s previous activities, logged before joining but after the start date (max 60 days), are automatically added to the challenge when they join. If a challenge lasts longer than 60 days, then our platform will only backfill 60 days’ worth of activities. You can always see when you joined on the main challenge dashboard.
