California International Marathon

Sunday, December 6, 2026 · Sacramento, USA · 7:00 AM

Updated Oct 17, 2026

One of the top Boston Qualifier routes in the US, with a high concentration of Olympic Trials Qualifiers. The sweeping, gently rolling net-downhill terrain and minimal turns make it BQ-friendly. Net drop of 366ft complies with Boston's index rules (which penalize >1,500ft drops from 2027).

Is the CIM Marathon hard?

No, not as marathon courses go. The CIM Marathon scores 2.4/10 on the Kenyan Running Difficulty Index, tied for the 5th easiest of the 12 marathons we rate.

The score is built from four factors: hills, race-day weather, turns and bridges, and the late miles where a runner is most likely to lose time. See the score breakdown.

Pacing the CIM Marathon

Print a pace band for the CIM Marathon. On the climbs, run even effort, not even pace: expect to fall behind the band going up and to win the time back coming down.

The score breakdown

Topographic Stress (30% weight)2.5 / 30
Atmospheric Stress (20% weight)6.0 / 20
Course Friction (15% weight)1.5 / 15
Tactical Brutality (35% weight)12.0 / 35

Score confidence: preliminary. Computed from public course, weather, and prize data.
