The Course: Why Runners Keep Choosing CIM
Part of what makes the CIM Marathon persistently attractive — for elites and everyday runners alike — is the carefully designed course:
- Point-to-point layout: The race begins near Folsom Dam and finishes at the California State Capitol in Sacramento. Wikipedia+2Sunrise Running Company+2
- Net-downhill profile: The route drops from an elevation of approximately 359 feet at the start down to roughly 19 feet at the finish, making it one of the most downhill-friendly major marathons in the U.S. Find My Marathon+1
- Rolling early terrain, smooth downhill finish: The first portion moves through gently rolling foothills and suburban areas, while the latter portion benefits from sustained downhill terrain — a recipe for personal bests and fast times. Find My Marathon+2Sunrise Running Company+2
- Well-supported course logistics: With 17 aid stations spaced throughout the route, runners had access to water, hydration mixes, gels, and fruit — ensuring sustained performance and comfort from mile one to the finish. Runsra+2Runsra+2

Race Weekend Events: Community, Expo, and Runner Support
CIM 2025 offered much more than the marathon itself. The full race weekend delivered a host of events and support opportunities:
- CIM Race Expo: Began Friday, December 5, at a new Expo location at Cal Expo — where runners collected bibs, met pacers, checked out sponsors, and picked up final race instructions. The Expo remained open Saturday as well. kcra.com+1
- Shakeout run: A 2-mile shakeout run was held Saturday morning at a downtown plaza near Sacramento’s riverfront — giving runners a final chance to loosen up and connect with the running community before race day. kcra.com+1
- Transportation & gear logistics: On race day, official shuttles transported runners from the staging area to the start. Gear check opened in the early morning hours, avoiding last-minute stress for participants. kcra.com+2Runsra+2
- Course support and safety: Thanks to efficient planning by organizers, all runners had access to fluids and fueling, and hydration and aid stations remained well stocked throughout the course. Road closures and re-open timings were also clearly communicated. Runsra+2Runsra+2
These elements contributed to a smooth, organized race day experience — whether for elite competitors chasing fast times or runners simply looking to enjoy the marathon journey.
Participation, Community, and the Spirit of CIM
Beyond elite competition, the 2025 CIM Marathon embodied a strong sense of community and spirit that defines the event year after year. The broad participant base — from elite runners to first-time marathoners — created a vibrant, inclusive atmosphere. Many participants ran for personal goals, charity causes, or to earn a Boston qualifier, while local volunteers and spectators lined the course, cheering on every pace group. kcra.com+2Sunrise Running Company+2
Moreover, the organizing Sacramento Running Association (SRA) continues to uphold high standards for logistics, runner safety, and community engagement — from pre-race communications to post-finish support. This year’s execution reflected the association’s commitment to making CIM an accessible marathon for diverse kinds of runners. Runsra+2Runsra+2
The race also serves as a hub for ambition: many participants use the event to qualify for larger marathons, chase personal bests, or build momentum for their next racing goal. The course’s downhill advantage, combined with organized race support and the winter weather typical of early December in Sacramento, continues to make CIM a strategic choice for timing a peak marathon performance.
