# How to join a team challenge

Team challenges (such as the Ülemiste City step challenge) allow you to compete as a team against others. To join, you’ll need the Activate app and a team code from your team captain.

**How to join:**
1. Open the Activate app.
2. Go to **Challenges → Public challenges** and find the challenge you want to join.
3. Tap **Join** and enter your team code when prompted.
4. You’re in! Your steps will start counting from the moment you join.

**Good to know:**
• Steps earned *before* you joined the challenge will not appear in the challenge leaderboard. Only steps from the moment you join are counted.
• Make sure you have connected a device or health app (Apple Health, Health Connect, Garmin, etc.) before joining so your steps are tracked.
• You can set an alias (display name) when joining. This can only be changed by leaving the challenge and rejoining, which resets your points to zero.
• Joining a challenge is free — you do not need a paid membership to participate.
• If your team code isn’t working, double-check the code with your team captain. Make sure you’re registering with the same email used in the Activate app.
