Valley Spokesmen Bicycling Club is celebrating the 42nd annual Mt. Diablo Challenge, an 11.2-mile ride that climbs to the summit of Mount Diablo, one of the highest peaks in the Bay Area. It is a 3,249-foot climb up South Gate Road through Mount Diablo State Park that is closed to cars or cyclists not involved in the challenge. What's exceptional is that Mt. Diablo's road will be car-free, giving more than 800 cyclists an exclusive opportunity to pedal their way up one of the San Francisco Bay Area's loftiest peaks. A vista from the summit on a clear day might even reward you with views stretching to the Farallon Islands and the Sierras. It's an event that the team at Strambecco considers to be one of the Best Road Cycling Events in California and the Southwest.

Mt. Diablo Challenge was previously hosted by Save Mount Diablo but has been taken over by Valley Spokesmen Bicycling Club since 2017 to broaden participation and emphasize family participation. Donations made during registration benefit Save Mount Diablo.

Event & Course Info

Starting from the Athenian School, cyclists at the Mt. Diablo Challenge will ascend South Gate Rd, eventually reaching Summit Rd, and finally, the summit itself. This 11.2-mile journey, with its 3,249 feet of elevation gain, promises a challenge. From road bikes (single or tandem) to mountain bikes, fixed-gear, unicycles, and outdoor elliptical bikes, diversity is encouraged. E-bikes of Class 1 & 3 are permissible, albeit without eligibility for awards.

While there's limited water at the starting point, hydration is available en route. The summit welcomes participants with a spread of coffee, water, energy bars, and other snacks. Additionally, bike mechanics will be stationed both at the beginning and the peak. However, note that no SAG vehicles will patrol the course.

With waves of cyclists based on estimated finish times, the first wave is flagged off at 8:15 am. Those in the first waves enjoy the privilege of the entire road width during ascent. However, post-celebration at the top, all must adhere to a descending protocol, ensuring safety.

The ride culminates in a grand celebration at Monte Vista High School, with BBQ, music, drinks, and awards. Beyond the ultimate titles of King and Queen of the Mountain, prizes await in 17 age categories. With separate podiums for men and women and special awards for the oldest and youngest participants, the Mt. Diablo Challenge ensures that every pedal stroke counts.

There is a field limit of 1,000 riders, ensuring a manageable and enjoyable experience for all, and while vehicular access to the mountain is restricted during the event, loved ones can join in the after-ride celebrations at Monte Vista High School.

Spanning 32 miles from Concord to Pleasanton, the Iron Horse Regional Trail runs right through Danville, making it a convenient starting point for cyclists looking to put in some extra miles. Originally a railway track, this multi-use trail has been repurposed for pedestrians, horse riders, and cyclists, providing a safe and scenic route through the East Bay. With its flat terrain, the trail is suitable for cyclists of all levels. As you pedal along, you'll pass through a mix of urban and rural landscapes, including serene parks, bustling town centers, and picturesque open spaces. Given its length, cyclists can choose to tackle the entire trail or just a segment, making it customizable to individual stamina and time constraints.

For those with a penchant for climbing, the Castle Rock Regional Recreation Area offers a unique opportunity to test your skills. Situated just a short drive from Danville, this park is renowned for its sandstone boulders, making it a favorite spot for bouldering enthusiasts. The area caters to climbers of all levels, from beginners to experts. Apart from bouldering, the park also has picnic areas and hiking trails, making it a versatile destination for a day out. As the Fall colors set in, the contrast of the orange and brown hues of the rocks against the changing foliage provides a picturesque backdrop for climbers.
