Bay Area 100

Updates

Bay Area 100 is a Western States qualifier. The road to Bay Area 100 starts with Dick Collins Firetrails. That's why we created the Firetrails 100k + Bay Area 100 Bundle . Register for the 100K at Dick Collins Firetrails and the 2027 Bay Area 100 together and save 15%. Available only through Dick Collins Firetrails Registration. Click here. Welcome Please join us at the 2nd running of the Bay Area 100 on June 12, 2027. Starting at the gates of California Memorial Stadium, you'll experience a 100-mile journey through some of California's most breathtaking terrain. The course both inspires awe and challenges runners: 100 miles point-to-point, 18,000ft of vertical gain, 33 hours to finish. Ridgelines, redwoods, weather extremes, panoramic views stretching from the Golden Gate to Mt. Diablo. And there's something more that makes this race special — the people who run it, crew it, pace it, and cheer it. More than twenty Bay Area running and community groups played major roles in getting runners to the finish line in 2026, and they're excited to take part again. With so much commitment and participation, we're hearing the Bay Area 100 referred to as "The People's 100": tough enough to earn, approachable enough to attempt, and supported in a way that inspires success Registration Timeline We're capping the 2027 field at 300 runners. We will offer rolling registration starting in the summer that will allow you to register after we review your entry. Then we will move to a waitlist. Waitlisters will all be invited to enter on December 9 (Waitlist Wednesday!) and be entered in a first come, first served basis. Here are the dates: July 15 – Pre-Registration: Deferrals and 2026 alumni will be invited to enter. Open enrollment athletes will be invited to enter on August 3. August 3 – Open Enrollment: Open registration up to 200 runners. Everyone else will be added to the waitlist. December 9 – Waitlist Wednesday: Waitlist offers for remaining slots. After this we will move to a rolling waitlist. Remember you can defer you entry up to 30 days before our race. The Course The Bay Area 100 feels as remote as a mountain hundred, but it runs on the edge of a major metroplex — which means your crew, your family, and your friends can actually get to you. With 18,000ft of vertical, this race is designed to challenge you while also showing you the best views, ascents, and descents the SF/Bay Area has to offer. Navigate across bay crests and exposed ridges, through redwood forest, and along lake shore on fire trail as you push through Bay View, Las Trampas, Lake Chabot, and Redwood territories. Each section offers its own unique triumph. Time Limits, Cutoffs, Aid Stations The Bay Area 100 starts at 5am and has a 33-hour time limit. There will be no early start this year. There will be cutoffs starting at 10:00 am. All aid station locations will be presented in the 2027 Athlete Guide, which will be available mid-August. Qualifying Times to Enter We recommend a 50-mile race within a year of running this race. You'll be asked for your race, its date, your time during pre-registration. If you do not have a qualifying time, you'll also have an option to ask for an exception. Our goal is to simply ensure you are likely to succeed. Qualifying Status - WSER / UTMB The Bay Area 100 is 2028 Western States Qualifier as well as a UTMB Index race. Deferrals and Cancellations Bay Area 100 allows you to defer your entry up to 30 days before race day. This is a 100% rollover to the 2028 race.
