It is not clear how Young advanced to the final; the Official Report says in the results of this heat that Coeckelberg and Denny qualified as having led the most laps, and in the description of the final field says that Young was "permitted to start, having satisfied the judges that he was not lapped in Heat 2."| Rank | Cyclist | Nation | Time | Notes |
