The following steps will help you import your Float data into Ludum. Please note that the sessions need to be the same for the import to work. E.g. A 2000m session in Float can be imported to a 2000m session in Ludum.
Go to the session
Select the import tab
Choose Float as the import
Find the session from the list of sessions
Press import
The session should import and be displayed in the data on the Ludum Web App.
If the sessions are not the same you will receive an error.
