Quick n’ Dirty MTB’s 12th Annual Filthy 50+ returns to the San Pasqual Staging Area on Halloween, Saturday, October 31, 2026. The community-focused endurance event offers a timed 52.2-mile route with 3,195 feet of climbing, a 30-mile out-and-back, and a one-mile kids course. Adult starts are 8:00 AM for the 50+ and 8:30 AM for both 30-mile groups; the age-11-and-under kids race starts about 8:45 AM. The long route continues from San Dieguito River Park into Black Mountain Park on a reverse-lollipop layout. Pink flags and red arrows mark the course, and four feed-station visits provide hydration, food, Hammer Nutrition products and self-help mechanical supplies. Trails remain open to hikers, equestrians and other riders, so racers must yield and pass courteously. Registration is currently open through BikeSignup at $155 for the 50+, $135 for the adult 30-mile, $105 for the ages 12–15 school division and $20 for the kids race; all four prices rise later. The live registration periods extend into race morning, but only the kids race explicitly advertises onsite signup, and the organizer warns that the event can sell out with waitlists opening when full. Check-in is published as 6:00–7:45 AM by the registration host and 6:00–7:30 AM by the organizer, so arrive by 7:30. Riders receive electronic timing, marked courses, feed support and event swag; the finish-area program includes a Halloween costume party, live entertainment, vendor village, food for purchase and a raffle benefiting San Dieguito River Park Bike Patrol. The expert men’s and women’s 50+ fields each carry a $2,500 purse. No official event end time, total capacity, current spectator gate policy, livestream or 2026 results are published.

RFID electronic timing uses a tagged number plate mounted unobstructed on the front of the bike. Riders must start in their registered class, follow the marked route, complete the assigned distance/laps and cross the finish with the bike. Shortcuts cause disqualification; missing the route/laps causes a DNF. The kids course is one mile per lap: one Beginner lap, two Sport laps and three Expert laps.

12th Annual Filthy 50+ — Escondido 2026

San Pasqual Staging Area

Quick n’ Dirty MTB brings E-Dirty Cross back to Lake Hodges for its fifth edition on Saturday, December 5, 2026. The e-mountain-bike race runs alongside the separate Dirty 30 and uses the Lake Hodges Boat Ramp as its check-in, pre-ride and start hub. Check-in and course access begin at 7:30 AM, racing starts at 9:00 AM, and awards follow as soon as racing concludes; the organizer has not yet published the course, wave order, lap count, finish cutoff or end time. The announced field includes open men’s and women’s divisions for Class 1 and Class 3 pedal-assist e-bikes. Factory-installed motors and permanent class labels are required, throttles are prohibited, Class 1 assistance must stop at 20 mph and Class 3 assistance at 28 mph. Staff may randomly inspect bikes before racing, will inspect the top three after racing, and may GPS-test the top five on a flat one-sixteenth-mile segment. The current organizer page quotes $60 for Expert, Sport and Beginner entries and $50 for School Boy/Girl entries, with a $10 increase on December 4. It says online registration will remain available until race start, but no current 2026 checkout link is exposed; the old BikeReg destination resolves to a completed 2022 event and is intentionally not presented as active. Registration is therefore marked not yet open rather than closed. The event is a regional Los Angeles-area exception: Lake Hodges is roughly 110 road miles south of central Los Angeles and provides a specialized permitted e-MTB race format and trail venue not available in the urban core. The land manager’s standing public-trail policy normally permits Class 1 and 2 e-bikes but prohibits Class 3, while the organizer explicitly announces Class 3 race divisions; because the 2026 course is still TBA, Class 3 riders should obtain organizer confirmation that the final permitted event route and event authorization cover their category before registering or traveling.

The exact course and lap/wave structure are TBA. Quick n’ Dirty uses RFID-tagged front number plates under its general rules. Riders must start in the registered class, follow the marked course, complete assigned laps and cross the finish with the bike; shortcuts cause disqualification and incomplete laps cause a DNF. E-bike compliance may be checked before and after racing and by GPS speed test.

Class 1 Men Open

Class 1 Women Open

Class 3 Men Open

Class 3 Women Open

Announced for pedal-assist Class 1 and Class 3 e-mountain bikes with a factory-installed motor and permanent class label. Throttles are prohibited. The page also references Expert, Sport, Beginner and School Boy/Girl price groups, but does not publish their exact mapping to the four open class/gender categories.

Organizer says online registration will be available until the 9:00 AM PST race start, subject to the 2026 registration link becoming available and any capacity limit not yet published.

The race is upcoming. No 2026 start list, timing link, results, podiums, livestream or replay has been published. The organizer says awards will follow as soon as racing concludes.

Quick n’ Dirty E-Dirty Cross — Lake Hodges 2026

Lake Hodges Boat Ramp

Quick n’ Dirty MTB closes its 2026 calendar with the Dirty 30 at Lake Hodges on Saturday, December 5. Mountain-bike and drop-bar riders take on one 34-mile lap combining hard-packed gravel, rolling fire roads, punchy climbs and technical singletrack along the lake’s north shore, with approximately 1,850 feet of climbing. The organizer specifically names Raptor Ridge and Highland Valley Trail as connecting areas that may form part of the final route and says Hammer Nutrition plus other supplies will be available at aid stations; the exact course file, aid-station positions and cutoff remain unpublished. Check-in and course pre-riding open at 7:30 AM PST, and racing starts at 9:00 AM. The field is presented for men and women on mountain bikes or drop-bar bikes, with age bands 16–17, 18–19, 20–29, 30–39, 40–49, 50–59 and 60+, plus Single Speed 16+ and Big Boned (200+) 16+ classes. The page does not spell out whether every special class is split by gender, so no extra split is inferred. All classes are listed at $100, increasing to $110 on December 4. The organizer says online registration will remain available until the race starts, but its current 2026 page does not expose a checkout; an older BikeReg slug resolves to a completed prior event and is intentionally not offered as active. Registration is therefore marked not yet open rather than closed. Quick n’ Dirty’s standing rules require helmets, prohibit headphones and shortcuts, and use an unobstructed front RFID number plate for scoring. Entries are final and nonrefundable. The event is a regional Los Angeles-area exception: Lake Hodges is roughly 110 road miles south of central Los Angeles and supplies the extended mixed-surface trail network and permitted endurance-race setting unavailable in the urban core. Spectator access, participant capacity, waiver and guardian rules, parking fees, accessibility accommodations, weather thresholds, race waves, awards, livestream and a finish time have not been published and should be confirmed before travel.
