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.
