Race-morning weather history
Coastal early-October race where heat, not cold, is the risk: a forecast 89F pushed every 2024 start 30 minutes earlier on race week, and the 5:30 AM gun stuck. Typical mornings are cool marine-layer damp with rapid warming over the 7.5-hour limit. 2020 cancelled (COVID). Wyndo tracks what past editions of the race actually served up at the start hour — temperature, dew point, wind, and rain, and reads the live forecast for the start once race week arrives.

Race facts
- Start line
- Shoreline Drive at Shoreline Village Drive, downtown waterfront (Rainbow Harbor); finish at Marina Green ~500 m east. Coordinates are the OSM intersection node — approximate at street-block resolution.
- Scheduled start
- 5:30 AM (America/Los_Angeles) — Official 2026: marathon 5:30 AM PT, half 7:00 AM PT, both from Shoreline Dr & Shoreline Village Dr; Aquarium 5K 6:50 AM Sat from a separate start. The 5:30 gun is the legacy of 2024's race-week heat amendment (scheduled 6:00 moved to 5:30 for an 89F forecast) and has been the published time since. No wheelchair/elite gun published for 2026 (one existed in 2024 at 5:25) — 'single mass start' is unverified, not confirmed.
- Field size
- Marathon finishers, 2025 edition, per FindMyMarathon (aggregator; not corroborated at the marathon-only level — press coverage gives only weekend figures).
- Registration
- open (ACTIVE Network, price tiers; capped — 2026 sold out, 2027 waitlist)
