CIM Pace Calculator & Race Plan
CIM (California International Marathon) is a fast, net-downhill course that drops about 300 feet from Folsom to the State Capitol in Sacramento. It's a popular BQ course because the net downhill helps, but the early downhill miles can wreck your quads if you're not careful.
The first 10 miles have the most descent, and it's tempting to let gravity do the work. Our model builds in quad damage from the downhills so your late-race splits reflect what actually happens when you've been braking on descents for an hour.
