Course & elevation
Santa Rosa is flat to gently rolling, with much of the route on the smooth Joe Rodota and Santa Rosa Creek trails through Sonoma wine country. The fast profile makes it a popular BQ course; late-summer heat is the variable to plan for.
- Start → Finish
- 160 → 170 ft
- Net
- +10 ft
- Total gain
- ≈ 800 ft
The certified route
An out-loop-back course from downtown Santa Rosa: west on 4th St, north up Fulton Rd, looping through the Piner Rd and Olivet Rd area, and returning via Fulton Rd to the finish on 4th St.
- Start
- 4th St at the center of the huge flower pot with sign at 619 4th St, 51 ft west of the 2-hour parking pole at 621 4th St and 24 ft east of the pedestrian crossing pole.
- Finish
- 4th St at the Kress location of the starting line, just below the K in the Kress sewer drain cover, 7 ft east of the storm sewer drain cover.
Underfoot
Mostly paved, with about 4 percent dirt.
Through, in order

- Mile markers are documented in the packet.
Transcribed from the USATF certificate for Santa Rosa Marathon (CA17049RS), measured 24 and 25 June 2017. Where the certificate is silent, so are we.
Key moments
- Mile 1–8Flat town and trail miles. Start controlled before it warms up.
- Mile 9–22Smooth bike-trail miles through vineyards; hold goal pace.
- Mile 26Finish near Railroad Square downtown.
Pacing strategy
Even pacing on the flat course, but start conservatively, because the August sun can build through the morning. Bank heat tolerance, not time.
Pacing by goal time
Checkpoint splits for four common goals at Santa Rosa 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.
| Checkpoint | Sub-3:00 | Sub-3:30 | Sub-4:00 | Sub-4:30 |
|---|---|---|---|---|
| Mile 3.1 | 20:396:45/mi | 24:057:52/mi | 27:318:60/mi | 30:5810:07/mi |
| Mile 6.2 | 41:257:01/mi | 48:198:11/mi | 55:139:22/mi | 1:02:0710:32/mi |
| Mile 9.3 | 1:01:556:58/mi | 1:12:148:08/mi | 1:22:339:18/mi | 1:32:5210:27/mi |
| Mile 12.4 | 1:22:266:45/mi | 1:36:107:53/mi | 1:49:559:01/mi | 2:03:3910:08/mi |

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.
Plan your mile splits
Turn your goal time into a mile-by-mile plan for Santa Rosa Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.
Plan Santa Rosa Marathon splitsFueling & hydration
Aid stations roughly every 2 miles with water and sports drink. Warm mornings raise fluid needs, so drink early and keep electrolytes coming.
Weather
Late-August Sonoma County mornings are cool but warm quickly under the sun; heat late in the race is the main risk.
What race morning has actually been like
The last 5 editions of Santa Rosa Marathon, measured at the start line rather than averaged across the month. Starts have run 53–57°F, averaging 56°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2021 | Aug 29 | 57°F | 55°F | 7 mph | 78°F |
| 2022 | Aug 28 | 57°F | 56°F | 13 mph | 67°F |
| 2023 | Aug 27 | 53°F | 52°F | 5 mph | 74°F |
| 2024 | Aug 25 | 57°F | 53°F | 7 mph | 77°F |
| 2025 | Aug 24 | 57°F | 55°F | 10 mph | 69°F |
The gap between the gun and late morning matters here. In 2023 it went from 53°F at the start to 74°F by late morning. A four-hour finisher ran a materially different race from a three-hour one.
Dates derived from the race's published pattern (Sunday in late August (4th Sunday; 2021 was the 5th Sunday)), observations at Santa Rosa, CA (start). Source: Open-Meteo historical reanalysis (ERA5), 7-11am local at the start line. Reanalysis is modelled from station observations, so treat it as a close record rather than an official one.

Is Santa Rosa Marathon a good Boston qualifier?
Yes. The course actually finishes 10 ft higher than it starts, so no downhill adjustment applies, and nobody can accuse the time of being gravity-assisted.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
Compare every course, how the downhill bands work, or work out your own target.
