Course & elevation
Napa Valley runs point-to-point down the rural Silverado Trail with a gentle, runnable net descent and only mild rollers to interrupt it. The smooth grade through vineyard country makes it a popular, low-key PR and Boston-qualifying course; the scenery and quiet roads are the draw, with the soft downhill as the bonus.
- Start → Finish
- 395 → 56 ft
- Net
- −339 ft
- Total gain
- ≈ 170 ft
Key moments
- Mile 1–6Easy early descent on the Silverado Trail. Relax and let the gentle grade set your pace.
- Mile 7–20Rolling vineyard miles trending downhill; hold steady goal pace without pounding the dips.
- Mile 24–26.2A flatter, more populated finish into Napa. Push through the wine-country home stretch.
Pacing strategy
Run the gentle descent with light, quick turnover rather than braking, and even effort yields a comfortably fast time. The grade is mild enough that quad damage is minor, but stay relaxed on the early miles to leave something for the flatter finish.
Pacing by goal time
Checkpoint splits for four common goals at Napa Valley Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.

Grade adjustment is a model, not a promise. It assumes even effort and ignores wind, heat, and how well your legs handle sustained descent — which on a steep course is often the deciding factor.

Fueling & hydration
Aid stations sit roughly every 2 miles with water and sports drink along the rural trail. The soft downhill rhythm makes fueling easy to overlook, so keep a disciplined gel schedule and the final miles will hold.
Weather
Early-March in Napa is cool and often damp at the start (40s°F), with spring green hills and the chance of rain — generally fast, comfortable racing conditions.
Is Napa Valley Marathon a good Boston qualifier?
Yes. The course drops 339 ft net, comfortably inside the 1,500 ft threshold where Boston's downhill adjustment begins, so a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
