Hum Up Um

Sierra Azul - Mt Umunhum

San Jose, CA 3.7 Miler

This Event Took Place Wed. Feb 19, 2020

Welcome to "Hum Up Um"

The Trail Portal, Pacific Coast Trail Runs, and The Running Revolution are jazzed to kick off the 2nd annual Hum Up Um. This 7.8 mile journey from Bald Mtn Parking lot on Mt Umunhum Road to "The Cube" and back is one of our favorite courses to run. About the Cube atop Mount Umunhum (Home of the Ohlone Indians of California, means resting place of the hummingbird) is the fourth-highest peak in California's Santa Cruz Mountains (after Loma Prieta, Crystal Peak, and Mt. Chual). The mountain is situated in Santa Clara County, south of San Jose. It is sometimes referred to as Mount Um by locals. Most of the mountain is within the Sierra Azul Open Space Preserve.

The mountain is topped by an 8.5 story (84.5 feet tall) concrete radar tower (5 floors interior), known locally as "the Cube" or "the Box". The tower was built in 1957 as part of Almaden Air Force Station, a radar surveillance post which operated from 1958 to 1980. The Cube, which housed an 85.5-ton AN/FPS-24 radar, was completed in 1962 and used to watch for hostile aircraft during the Cold War. Its signal put an electronic zip into every radio, TV and sound system within its 250-mile range on every rotation.

Open Course Trail Racing

What is Open Course Trail Racing?
Open Course Trail Racing is a new category of racing that was spawned by the creative energy of Pacific Coast Trail Runs. This new technology, developed with our partner PWRLab, enables race directors to produce events which provides runners with an experience that feels as close to “live” or “in-person” racing as possible. "Live/In-person Racing" is what you knew up until the pandemic. "Open Course" allows for you to run the actual course that was designed by the Race Director. You will run the course on your time, at your own pace, during the event time period in compliance with the local park rules.

Open Course for Race Directors
• Allows you to produce your event more than one day per year by digitizing and monetizing.
• Allows you to safeguard your brand against someone else producing an event on your course.
• Provides a safety net to protect your organization against loss of permit due to the pandemic, fire, or other cancellations.
• Allows for you to produce a safe event.

Open Course for Runners
• Allows for you to run the course of all your favorite races.
• Allows for you to compete on the actual event course against others.
• Your time will be validated similar to a timing chip on the back of your bib.
• Your name will populate on the leaderboard like a normal live/in-person event.

Are You Ready to Race?
If yes, then:
1. Register Above via UltraSignUp.
2. Receive UltraSignUp confirmation email from Race Director (Check Spam Folders).
3. Follow Email instructions to launch syncing technology.
4. Choose "On-Course" or "Off-Course" (See Below Descriptions)
4. Compete & Connect with the trail Community.
5. Run the course as many times as you would like during the event window to climb the leaderboard.
6. Celebrate!

Mountain Lions ALERT – Big cats are very actively and thriving in the Sierra Azul and the nearby Santa Cruz mountain ranges. They are most active around dusk and dawn. Locals have reported frequent sightings so encountering them is VERY REAL. The segment to the summit is lined with tree covers and not always well traveled by hikers/runners. Due to the remoteness of this location, exercise caution and vigilance at all time during your run. Avoid using earbuds or loud music that will tune you out from your surroundings.

Check out this video, bit.ly/MtUmMountainLions, of mountain lions sightings at Mt Umumhum. Pay specific attention to the time of day in the footage. Your safety is our number one priority so please educate yourself in the unlikely event should you do encounter a mountain lion. We highly recommend running as a group or with a buddy. Feel free to post in our Strava Club, bit.ly/HumUpUmStravaClub, to organize your own meet-ups.
