Registration for the 2012 Milwaukee Lakefront Marathon opened on Sunday, starting the race for the 3,100 slots in the run from Grafton to Veteran’s Park on Oct. 7.
Organizers expanded the marathon capacity to 3,100 runners for the 32nd edition. In 2011, the field of 3,050 filled in mid-April.
Demand for marathon entries has increased in recent years and organizers dropped a relay event and opened up the race to more runners last year.
