California International Marathon (CIM) Training
Chase your Boston Qualifier at CIM with data-driven training zones from VO₂ max testing. Master the net-downhill course with precise pacing strategy and optimal training zones.
The California International Marathon is renowned as one of the fastest courses in the nation, featuring a net downhill elevation profile from Folsom to Sacramento. It's a favorite for Boston Marathon qualifiers and PR attempts.
However, the downhill nature requires specific pacing discipline-going out too fast is easy on the early downhills but leads to quad destruction later. VO₂ max testing provides the physiological data to pace perfectly.
December weather in Sacramento is typically cool and dry-ideal marathon conditions when you're properly prepared.
Controlled Marathon Pace: Your sustainable race pace accounting for the downhill boost-preventing early burn.
Eccentric Strength Work: Zone 2 downhill running to prepare quads for race day pounding.
Threshold Runs: Build lactate clearance for sustaining faster-than-normal marathon pace.
Long Run Pacing: Progressive long runs simulating the CIM negative split strategy.
CIM takes place in early December, requiring strategic fall training:
August/Early September: Initial VO₂ max test to establish base training zones for 16-18 week training block.
October: Mid-cycle retest to verify fitness gains and adjust zones for peak training phase.
Early November: Final test to lock in race pace strategy and confirm BQ pacing plan.
Boston Qualifying requires hitting a specific time standard-no room for guessing. VO₂ max testing removes the guesswork.
We'll help you determine:
- Your exact BQ pace range based on your current fitness
- Whether you're ready to hit your age-group standard
- How much buffer to build in for BQ cushion (competition is fierce!)
- Pacing strategy for the first downhill half vs. flat final miles
Santa Cruz offers excellent CIM training terrain:
- Empire Grade to UCSC: Long downhill runs to prep legs for eccentric loading
- West Cliff Drive: Flat tempo runs for race pace work
- Pogonip: Variable terrain for strength building
- Nisene Marks: Long trail runs for endurance base
Your VO₂ max zones guide intensity on all these training routes.
Many Sacramento-area runners travel to Santa Cruz for weekend long runs and prefer to test in an optimal environment. Our facility offers:
- Sea-level testing for accurate baseline (Sacramento is ~25 feet elevation)
- Natural ventilation from ocean breeze
- Korr CardioCoach metabolic analyzer-gold standard accuracy
- Multiple equipment options (treadmill, bike, rower, stair mill)
VO₂ Max Test: $250
Includes BQ-specific pacing recommendations, personalized zones, and CIM course guidance.
