When is the Central Coast Dirt 100 in 2026?

Sunday, October 18, 2026 at Lake San Antonio in Monterey County, California. Confirm the exact start time, kit pickup schedule and any pre-race briefing on repackracing.com/central-coast-dirt-100 as the date approaches.

Where is the Central Coast Dirt 100 held?

Lake San Antonio in Monterey County, California — a large inland reservoir about 1 hour south of Monterey and 1 hour north of Paso Robles, inland from the Central Coast wineries. The race base is at Lake San Antonio; access is via US-101 south from Monterey / Salinas or north from San Luis Obispo.

How long is the Central Coast Dirt 100 and how is it structured?

The 2026 event runs a single 15-mile lap in three formats: a 30-mile race (2 laps), the featured 60-mile solo endurance race (4 laps) and a 60-mile DUO relay (4 laps split between two teammates). The 60-mile solo and DUO share the same finish line and course, so it is the featured category. The lap format means you pass the start/finish 1× on the 30-mile course and 3× mid-race (end of laps 1, 2, 3) plus the finish on the 60-mile course.

Is the Central Coast Dirt 100 actually 100 miles?

No — the 60-mile featured event is not literally 100 miles. The '100' in the name refers to the event's identity within the Repack Racing endurance-race calendar, not the race distance. The three actual distances are 30 miles (2 laps of 15) and 60 miles (4 laps of 15, solo or DUO relay).

How difficult is the Central Coast Dirt 100?

The 60-mile solo is a genuine endurance test: 60 miles of mixed fire road, doubletrack, singletrack and lakeside riding, repeated as 4 laps under October Central California sun, with 5–8 hour finish times. Trained amateurs prepare for months and treat laps 3–4 as the deciding section. The 30-mile course is a strong intermediate-endurance test but doesn't hit the same fatigue-and-fueling limits.

What terrain should I expect on each lap?

Each 15-mile lap combines fire road, doubletrack, singletrack and an extended lakeside section. The variety keeps intensity spiky rather than steady — punchy pitches on fire road, technical passages on singletrack, and rolling exposed lakeside doubletrack. Steady tempo pacing wins over surges.

How many carbs per hour should I target?

70–90 g/hr for most trained riders on the 60-mile solo, biased toward liquid and gel because you cannot safely chew in the singletrack sections. 60–80 g/hr on the 30-mile course. Trained guts can push toward 100 g/hr on longer efforts.

How much should I drink?

500–900 ml/hr for the 60-mile solo, adjusted for the day's temperature. Cool October morning starts mask sweat losses — drink to the clock, not to thirst. A pre-race sweat test is the only reliable way to personalize your target.

How many aid stations are there?

Aid is placed by Repack Racing at the start/finish plus any on-course support they set up for 2026. Mid-pack 60-mile riders should plan for 65–95 minute gaps between start/finish passes. Confirm the exact 2026 aid layout in the Repack Racing pre-race athlete communications.

What categories does the Central Coast Dirt 100 offer?

The event typically runs three formats — 30 miles (2 laps), 60 miles solo (4 laps) and 60 miles DUO relay (4 laps split between two teammates) — with age-group and sometimes Pro Elite subcategories within each distance. Confirm the current-year category list on repackracing.com/central-coast-dirt-100 or through the registration page.

How does the 60-mile DUO relay work?

Two teammates share the 4-lap 60-mile course, alternating laps or splitting them 2-and-2 depending on team strategy. Exchanges happen at the start/finish. Coordinate warm-up timing, shared fueling logistics (bottles, crew, tools) and lap strategy ahead of race day — a poorly coordinated DUO loses more time in transitions than on the trail.

How do I register for the Central Coast Dirt 100 2026?

Registration is handled by Repack Racing through the event page at repackracing.com/central-coast-dirt-100. Confirm current pricing, tiers and registration deadlines on the official site. First-lot pricing is typically discounted; register early to save.

What is a good Central Coast Dirt 100 training plan?

A realistic Central Coast Dirt 100 training plan for the 60-mile solo runs 12–16 weeks and hits three targets in parallel: aerobic volume (peak 10–14 hours/week for 8–12 weeks), threshold work (weekly 2× 20 min at 90–100% FTP), and repeated punchy-climb intervals (weekly 6–8× 3–5 min at VO₂ on 5–10% gradients). Long rides progress toward 4–6 hours with 3,000–4,500 ft of climbing on similar mixed-surface terrain. A 2-week taper with race-effort openers finishes the block. For the 30-mile course, an 8–10 week plan with shorter long rides (2.5–3.5 hours) is sufficient for most riders.

How should I prepare for the dry inland heat?

Run 8–12 heat-acclimatization sessions (sauna 20–30 min post-easy-ride, or indoor trainer in a warm room 45–60 min at moderate effort) in the 6 weeks pre-race. Practice race-morning breakfasts before dawn simulations to rehearse the cool October start. Test sodium and fluid targets on 4+ hour training rides in similar dry-heat conditions.

Where can I download the Central Coast Dirt 100 course map or GPX file?

The official 2026 route (single 15-mile loop, raced 2× on the 30-mile course and 4× on the 60-mile solo / DUO relay) is on RideWithGPS at ridewithgps.com/routes/57249991 with an inline elevation profile, and the GPX is available for direct download at fuelqpro.ai/gpx/CC100.gpx. Load the GPX into your head unit (Garmin, Wahoo) or sync the RideWithGPS route directly — once your device knows the loop, subsequent laps are turn-by-turn familiar.

Can I defer my Central Coast Dirt 100 entry?

Deferral, transfer and refund policies are set year-by-year by Repack Racing. Historically a partial refund window closes 30–60 days pre-event and limited transfers may be available for documented medical reasons. Always confirm the current-year policy on the official registration page — informal or late-request deferrals are not granted.

Do I need to qualify or enter a lottery for the Central Coast Dirt 100?

No. The Central Coast Dirt 100 is open registration — there is no lottery, no qualifier race series, and no prior-finish requirement to enter. Register directly through repackracing.com/central-coast-dirt-100 subject only to spot availability. First-lot / early-bird pricing typically saves money — register early.

Is there a partner benefit for Central Coast Dirt 100 athletes?

Yes. Repack Racing partners with FuelQ Pro so the first 20 eligible registered athletes can claim a sponsored FuelQ Pro Race Pack (retail USD 39, athlete pays USD 0). Access opens September 14, 2026.
