Race planning guide
How to choose a running race in California
Compare more than the date and distance. Open the official race page to review the exact start time, course surface, elevation, time limits, packet pickup, parking, accessibility, and refund or transfer policy before registering.
- Confirm the source: organizer pages control registration status, pricing, schedule changes, and cancellations.
- Check the course: road, trail, hills, altitude, and weather can make two events at the same distance feel very different.
- Plan race morning: verify the venue, parking instructions, start corral, and recommended arrival time.
- Match your training: leave enough time to build safely for the distance and recover before your next goal race.
