You can share your Stryd with other runners. Keep the following in mind:
1. Each runner can install the Stryd app on their phones and have their own accounts.
2. Weight and height affect the reported metrics. So, you may need to update the information when others run with your Stryd.
3. Each runner can set up his/her individual account in PowerCenter, so the Stryd data can be segregated for each runner.
