A couple hundred people are expected to show up at the historic Dole Mansion in Crystal Lake to run and bike for a total of 16.4 miles as this morning at the Fourth annual Run and Roll for the Dole Duathalon.

The popular race will both begin and end at the historic Dole Mansion after winding through Crystal Lake.

Last year more than 280 people signed up for the event and this year, 250 have registered so far. The majority of the participants are from Illinois, though some have traveled from states across the country including Wisconsin and California to take part in the event which participants in the past have said is great for running.
