Ventura, CAApril 18, 2027

Start around December 27, 2026. The calendar below gives each phase a real date, then the course guidance shows where to make the build specific to Mountains 2 Beach Marathon.

Does this window fit your starting point?

Use this window when you have a running base and want several weeks before the hardest marathon-specific work begins. The extra month over a 12-week plan creates more room for gradual long-run growth and recovery.

  • You run consistently enough that week one is a continuation, not a restart.
  • You want a distinct foundation phase before the biggest long runs.
  • You can protect your planned run days for roughly four months.
  • Your race date leaves the full window without forcing skipped weeks.

The 16-week Mountains 2 Beach Marathon calendar

These dates define the job of each phase. Your current mileage, recent longest run, experience, goal, and available days still decide the actual workouts inside them.

Foundation

Weeks 1–4

Dec 28, 2026–Jan 24, 2027

Establish repeatable weeks, keep most running easy, and begin extending the long run without forcing the pace.

Build

Weeks 5–10

Jan 25, 2027–Mar 7, 2027

Increase the weekly load, preserve step-back weeks, and introduce the terrain and effort the race will require.

Peak

Weeks 11–13

Mar 8, 2027–Mar 28, 2027

Complete the biggest race-specific weeks and use long runs to lock in fueling, pacing, and equipment.

Taper

Weeks 14–16

Mar 29, 2027–Apr 18, 2027

Bring volume down while keeping the weekly rhythm familiar. Training is finished before race week begins.

Make the window specific to Mountains 2 Beach Marathon.

Use the first month to establish consistency, then make long runs progressively more specific to the race's terrain and conditions. The course rehearsal should grow with the plan, not appear all at once in peak week.

How to train for Mountains 2 Beach

Train for Mountains 2 Beach by building eccentric quad durability, not only aerobic fitness. A 724 foot net drop means thousands of footstrikes land with your quads working as brakes, and that damage accumulates quietly through the middle miles. Runners who arrive fit but downhill-untrained lose the race around mile 19.

Start downhill work about twelve weeks out and build it slowly, because it is the one stimulus that leaves people sore for days. Begin with two or three miles of moderate descent inside a long run at goal effort and work toward eight or ten. Short quick steps, and no leaning back.

Train the opposite thing too. There are 536 feet of climbing here and a 6.4 mile cutoff at 8:05 a.m. that assumes you can move well through the opening loop, so keep hill work in the plan. A pure downhill specialist gets caught out in the first hour.

Rehearse the 6:10 a.m. start as well. That means a 3:30 or 4:00 a.m. breakfast, so do it for real on at least two long runs instead of discovering your stomach's opinion on race day.

16-week Mountains 2 Beach Marathon plan questions, answered.

When should I start a 16-week Mountains 2 Beach Marathon plan?

The 2027 Mountains 2 Beach Marathon is scheduled for April 18, 2027, so the 16-week window opens around December 27, 2026. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.

Is a 16-week plan long enough for the Mountains 2 Beach Marathon?

Use this window when you have a running base and want several weeks before the hardest marathon-specific work begins. The extra month over a 12-week plan creates more room for gradual long-run growth and recovery. The course does not change the opening load you can handle, so choose from your current mileage and recent longest run before adding race-specific terrain.

How should I prepare for the Mountains 2 Beach Marathon course in 16 weeks?

Use the first month to establish consistency, then make long runs progressively more specific to the race's terrain and conditions. The course rehearsal should grow with the plan, not appear all at once in peak week. Train for Mountains 2 Beach by building eccentric quad durability, not only aerobic fitness. A 724 foot net drop means thousands of footstrikes land with your quads working as brakes, and that damage accumulates quietly through the middle miles. Runners who arrive fit but downhill-untrained lose the race around mile 19.

What if the 16-week Mountains 2 Beach Marathon window has already started?

Do not double weeks or cram missed mileage into the remaining calendar. Use your current mileage, recent longest run, experience, goal, and available days to choose a plan that can enter at an appropriate point while preserving the taper.

How much does Mountains 2 Beach drop?

Mountains 2 Beach loses 1,260 feet and gains 536 across 26.2 miles, for a net drop of 724 feet. It starts just over 700 feet up in downtown Ojai and finishes at sea level in Ventura, and the race describes the route as descending to sea level over roughly 22 miles.

Is Mountains 2 Beach a good Boston qualifier?

Yes, one of the better ones. 18.3% of finishers ran Boston qualifying times in 2026, 21.6% in 2025 and 24.8% in 2024, on a USATF certified course. The catch is that the downhill only helps runners who trained for it. Untrained quads hand the advantage straight back after mile 18.
