The Isis Winter League (IWL) is a series of head races run throughout Michaelmas and Hilary terms. IWLs are open not only to OURCs affiliated crews, but also to other rowing clubs based on the Isis, so all are encouraged to participate. The course usually runs from Donnington Bridge to Cox's Stone opposite Christ Church Meadow.
In years with low water time (e.g. IWLs and/or Torpids are cancelled), the OURCs Committee may elect to hold an “Isis Spring League” in Trinity Term.
