The 2025 Bah Humbug! presented by the City of San Ramon is a great way to start the holiday season off with a healthy fun run or walk through San Ramon. Participants will receive a holiday long-sleeved shirt and the famous Bah Humbug! Ornament. This event is great for families and children! The Bah Humbug! is a chip-timed race.
