Worth the trip if the mountains match what you want.
The card
Miwok is the California 100K where worth is allowed to beat demand without becoming a brochure. Demand is 3: sixty-two miles, over 11,000 feet of gain, Stinson Beach to the Headlands and Tam, singletrack and dirt, a competitive front and a long day for everyone else. It is not 4 or 5 because the altitude is coastal, the technicality is trail, and the weather is Marin in May rather than a monsoon or a canyon furnace. You can have a hard 100K that is still not a mountain 100. This is that card.
Worth is 4 because the place is the product. Redwoods, ridgelines, cliffs, a finish in a town that still looks like a town. People fly for this 100K. That is destination, not regional. Lake Sonoma is the nearby 100K we would not tell you to cross a continent for. Miwok is the one we would. The Headlands are not a consolation prize for missing the Sierra Crest. They are a different sport: coastal climbing, fog, Pacific air, views that do not need a 14er to justify the weekend. Organization confidence is medium. The public description is consistent: excellent marking, volunteer culture, professional medical at aid.
The next edition is May 1, 2027. If you wanted Western States Trail, that is Canyons, with a circuit tax. If you wanted a mountain 100 in California, Angeles Crest is the other problem. If you wanted a 100K that is actually worth the weekend because of where it is, this is the card in this batch. Not a 5. Not a skip. Destination, on purpose. Worth beating demand is allowed when the place is the product.
Who it is for
Runners who want a coastal 100K with views that justify the flight, and who do not need 13,000-foot passes to feel they traveled.
Who should skip
Altitude chasers and anyone who will be disappointed that Marin is not the Sierra Crest.

Supporting dimensions · organization confidence medium
62 miles of Marin trail from Stinson Beach. A 100K, not a mountain 100.
Over 11,000 ft of gain. Coastal climbing, not alpine vert.
Singletrack and dirt road, about a mile of pavement. Technical enough for a 100K.
Early May on the Headlands: fog, wind, sun. Not a furnace, not a freeze.
Mount Tam, not a 14er. The air is Pacific.
An hour from San Francisco. Easy, which is why worth can outrun demand.
A classic with a real front and a deep age-group field. Not an icon 100.
Long-running, volunteer-famous, publicly described. Medium-high from the public record.
A destination 100K you can do without a lottery religion or a stones stack.
Redwoods, ridges, coastal cliffs. This is the worth 4.

Distance & format How much does the advertised distance and format actually ask? | 3 out of 5 | 62 miles of Marin trail from Stinson Beach. A 100K, not a mountain 100. |
Vertical How serious is the climbing, not just the mile marker? | 3 out of 5 | Over 11,000 ft of gain. Coastal climbing, not alpine vert. |
Technicality Hands, poles, route-finding, or just a long dirt road? | 3 out of 5 | Singletrack and dirt road, about a mile of pavement. Technical enough for a 100K. |
Climate Heat, monsoon, ice, or a friendly summer afternoon? | 3 out of 5 | Early May on the Headlands: fog, wind, sun. Not a furnace, not a freeze. |
Altitude Does the air change the race, or is it a talking point? | 1 out of 5 | Mount Tam, not a 14er. The air is Pacific. |
Logistics How hard is the weekend around the race: travel, crew, lodging, rules? | 2 out of 5 | An hour from San Francisco. Easy, which is why worth can outrun demand. |
Prestige & field Does the start list and history change what the weekend feels like? | 3 out of 5 | A classic with a real front and a deep age-group field. Not an icon 100. |
Organization From public evidence, does the event look competently run? | 4 out of 5 | Long-running, volunteer-famous, publicly described. Medium-high from the public record. |
Value Entry fee, travel tax, and lottery friction versus what you get on course. | 4 out of 5 | A destination 100K you can do without a lottery religion or a stones stack. |
Adventure & scenery Would you fly for the place even if nobody kept score? | 5 out of 5 | Redwoods, ridges, coastal cliffs. This is the worth 4. |
