The Blue Diamond Almonds Shamrock'n Half Marathon on Sunday is likely to undergo a course change because of flooding on the original route caused by recent storms.
The traditional 13.1-mile course starts and finishes at Raley Field. Along the way, runners pass Tower Bridge, the Capitol, the American River bike trail and Old Sacramento.
But this year the course will be changed to avoid portions soaked by the American River, which has swelled from increased water releases from Folsom Lake.
“We are making a course change to the half marathon,” said Dusty Robinson, general manager of Fleet Feet, the owner of the race. “The 5K on Saturday will be unaltered because it does not go through Discovery Park.”
Never miss a local story.
Robinson could not provide a description of the course change because the new route still must gain approval from the city of Sacramento and Sacramento police.
Race participants will get final instructions of potential changes on Thursday afternoon or Friday by email.
“Definitely, keep your eye on your emails,” said Robinson. “In general, aside from the route change, bands will be in place. The experience that is Shamrock’n will be in place. It will just be wet.”
The National Weather Service predicts rain for the region Sunday.
