Sources & method

Race date, start (7:30 AM, Milvia St at Kittredge St), finish (MLK Jr Way at Allston), 7 water stops, 630 ft official elevation, USATF CA18024DT: berkeleyhalfmarathon.com › Half Marathon (checked Oct 19, 2026).
Course line, water-stop and mile-marker positions: traced from the organizer's 2026 course map PDF (BHM-map-half-marathon.pdf, created Aug 3, 2026). The PDF's vector route was georeferenced to OpenStreetMap streets (affine fit refined by snapping to roads; median residual ≈ 2 m, 90th pct ≈ 9 m). Unverified: no official GPX is published; the traced line measures 12.86 mi before scaling and is scaled uniformly to 13.1 mi; markers printed on the PDF are approximate, so mile positions here are measured, not official. The site's course-maps page still shows a 2024 image.
Elevation: USGS 3DEP (~10 m), sampled every ~20 m, smoothed ±40 m; footbridge/overpass sections interpolated. DEM climbing (~598 ft) is a bit under the official 630 ft.
Plan (pace + HR): Goal 1:40–1:41 (Running Coach). Push-phase base pace 7:30 and the 175–182 HR band for miles 11–13.1 are our assumptions.

Course line, mile markers, aid station points, relay exchange, halfway, start/finish, cheer zones: SRA's official interactive CIM "Master Map" (Google My Maps, linked from runsra.org › Course & Aid Stations), exported as KML.
Aid station names, mile numbers, what's stocked, refill points: official aid station table on the same SRA page (2026).
Race date, net drop (366 ft), start waves/closing times: runsra.org › CIM and Start Line. Finish layout: Finish Line page (2025 info; SRA says 2026 details are coming).
Elevation: USGS 3D Elevation Program 1/3 arc-second (~10 m) DEM, sampled every ~25 m along the official line and lightly smoothed (±40 m). A cross-check against USGS 1 m lidar at the start (108.1 m) and finish (6.1 m) agreed to within 0.1 m. On the one mapped road bridge (Fair Oaks Blvd at the levee) elevation is interpolated deck-style between the abutments. Measured start/finish: . SRA's official figure is a 366 ft net drop; DEM-based climbing totals vary by source and smoothing, so treat them as approximate.
Distances: positions along the drawn line are calibrated piecewise to SRA's official mile-marker placements, so hover mileage matches the markers you'll see on course.
Road names, bridges and neighborhoods: © OpenStreetMap contributors (Overpass / Nominatim). Climb cross-check: Run Ready CIM course guide (Oct 2025), which also supplied the typical start temperature.
Goal splits & HR band: 3:30:00 goal and per-mile HR targets from Running Coach; split model and adjustments described on the Splits tab.
Pacing notes are general, conservative marathon guidance written for this course, not official SRA advice. Course details can change, so check SRA's race-week communications.
