I have done CIM two times, in 2013 in which it literally had freezing temperatures, and 2016, which had perfect weather. Since I was born and raised in Sacramento, and my entire family still lives there, I am partial to races in that area. CIM is a VERY organized race with tons of porta potties, aid stations, and crowd support. Throughout the course there were many encouraging volunteers to uplift your spirits when the going gets tough. It is technically a net downhill course, but do not be fooled. the course is essentially rolling hills until you get to downtown. That being said, I thought it was a good experience and it is a wonderful sight at the end to see the Capitol. I would do this race again and recommend it to others.
