Enter your goal time. Get hill-adjusted, mile-by-mile splits built from actual course data — including the opening Ojai climb, the Casitas Pass descent, and the Pacific Coast Highway finish run.
Mountains 2 Beach is deceptively simple on paper: start in Ojai, run to the ocean, finish on the Ventura Promenade. The 736-foot net downhill sounds like a gift. And in some ways it is — gravity does real work on this course, and splits come easier than a flat marathon suggests. But the gift has terms. Three miles of opening climb through the Ojai Valley, a long sustained descent through Casitas Pass that taxes quads for 15 straight miles, and a Pacific Coast section where the ocean breeze is beautiful but tired legs can still collapse a well-planned race.
This calculator helps you solve that problem by giving you an exact, step-by-step plan built on research, experience, and data. Enter your goal time, set how aggressively you want to handle uphills, and you'll get a target pace for every mile that closes exactly to your goal — accounting for every foot of climb from the Ojai start and every foot of drop all the way to the beach.
Enter your goal time and effort level. Your personalized mile-by-mile splits appear instantly.

Where the climbing lives, where the descent opens up, and why the Casitas Pass miles decide whether you finish strong or survive to the beach.
The race begins in downtown Ojai under the arched arcade of Libbey Park — a Spanish colonial street scene with palm trees, a mission-style bell tower, and somewhere around 3,000 runners packed shoulder-to-shoulder at dawn. It's one of the most photogenic start lines in California running. Then you run out of town and immediately start climbing.
Miles 1 through 3 are where Mountains 2 Beach earns the first half of its name. The course follows Highway 33 out of town and into the hills surrounding the Ojai Valley, climbing steadily for the first two miles before mile 3 delivers the sharpest single ascent on the course — approximately 84 feet in one mile. This is the summit approach. The views opening behind you toward the Pacific are worth the effort if you can spare the attention.
Mile 4 brings a brief reprieve as the terrain flattens near the summit area. Then mile 5 drops 100 feet — the single biggest downhill to this point — and the character of the race shifts completely. By mile 7, you've come off the mountain and the long descent toward the coast is fully underway.
This is where Mountains 2 Beach delivers its most unique challenge. Eight straight miles of net downhill through the Casitas Pass region, with Lake Casitas visible in the distance and the Santa Ynez Mountains receding behind you. The running feels deceptively easy. Your heart rate stays low. Your lungs are grateful. Your quads are quietly paying the bill.
Miles 10 and 11 are the steepest consecutive section of the course, dropping a combined 182 feet. The descent through Casitas Pass proper sends you down at grades your body has to brake against, mile after mile. By the halfway mark at mile 13, you've dropped over 350 feet from the opening summit — more elevation than the entirety of most "hilly" races — and you still have 13 miles to run.
Mile 15 flattens slightly as the terrain transitions from the pass to the broader coastal valley. This is a good moment to check your split and assess how your legs feel. If you've run your calculator targets through the descent, you should feel tired but controlled. If your quads are already burning at mile 15, you went out too fast on the downhills.
The approach to the coast brings the single most dramatic mile of descent on the entire course. Mile 18 drops 95 feet — the biggest net downhill of any single mile from start to finish — and arrives at a point when your legs have already absorbed 17 miles of sustained downhill running. It's a strange feeling: the terrain is helping, the ocean is getting closer, and your body is both grateful and spent.
By mile 20, the Pacific Coast Highway opens up ahead of you and the Pacific Ocean becomes visible for the first time. The transition from inland Southern California to the California coast is one of the most emotionally rewarding moments in marathon running. The breeze off the water is real, the scenery is genuinely spectacular, and there are still six miles left in your legs.
Miles 21 and 22 run along or near the PCH with ocean views and a gradual net drop that lets your pace open slightly compared to the rolling terrain earlier in the course. You've covered over 20 miles and descended more than 700 feet. The finish is now close enough to see in your mind, if not yet on the horizon.
The final section through Ventura is where the race resolves. After 22 miles of mountain terrain and coastal descent, the course transitions to city streets and harbor views for the closing miles. It's mostly flat — a welcome change for legs that have been braking against downhills for the better part of 15 miles — but flat miles after that kind of descent feel oddly hard. The terrain has done its job; your legs have to do the rest.
Mile 25 passes through the Ventura Harbor area, one of the more picturesque sections of Southern California coastline. Boats in their slips, pelicans overhead, and the smell of the ocean close. Mile 26 drops slightly toward the Promenade, a final small gift of elevation before the beach appears.
The final 0.2 miles threads onto the Promenade with the crowd gathered and the ocean loud on your left. If you've run your targets all the way from Ojai, the math closes exactly here. Miles of mountain, miles of descent, miles of coast — all summed up in the numbers on your watch at the finish line.
Late May in Southern California is typically warm and clear — but the Ojai Valley start and the Pacific Coast miles can create very different conditions in the same race.
Mountains 2 Beach runs on Memorial Day weekend in late May, when Ventura County weather is generally stable. The Ojai Valley start, at roughly 750 feet of elevation, tends to be cooler and sometimes cloudier than the coastal finish, which can run 10–15°F warmer by the time the bulk of the field finishes. Runners starting before 7:00 AM often experience mild conditions in the mountains that turn significantly warmer by the PCH section. The ocean breeze on the final miles is a consistent feature and tends to moderate late-morning temperatures for mid-pack finishers.
| Year | Start Temp | Finish Temp | Humidity | Wind | Conditions | Notable |
|---|---|---|---|---|---|---|
| 2024 | 55°F | 68°F | 70% | 8 mph W | Ideal | Mild morning in Ojai, pleasant coastal finish with a helpful westerly breeze. Strong year for PR attempts. |
| 2023 | 60°F | 74°F | 65% | 6 mph SW | Warm | Warmer-than-average Ojai start. Coastal miles provided relief, but mid-pack runners experienced heat stress through miles 15–20. |
| 2022 | 52°F | 63°F | 75% | 10 mph NW | Ideal | Cool and overcast — excellent conditions throughout. Finish temps stayed below 65°F even for back-of-pack finishers. |
| 2021 | 63°F | 78°F | 60% | 5 mph SW | Hot | One of the warmer editions. Finish temps hit nearly 80°F for late finishers. DNF rate elevated compared to cool-year editions. |
| 2019 | 57°F | 66°F | 72% | 9 mph W | Ideal | Pre-pandemic classic edition with excellent conditions from Ojai to the beach. Many runners reported PRs on the downhill course. |
The practical rule for Mountains 2 Beach: in cool years (Ojai start below 60°F), the downhill can be fully exploited and goal times are very achievable. In warm years, the final PCH miles amplify heat stress — the sustained downhill from Casitas already taxes your thermoregulation, and warm coastal air removes the breeze advantage. The hill adjustments in this calculator are accurate in all weather; your goal time estimate may need a conservative buffer in years when temperatures climb above normal.
With 736 feet of net downhill from Ojai to Ventura, M2B is one of the more BQ-friendly certified marathons on the West Coast — if you manage the descent correctly.
Mountains 2 Beach is certified by USATF and qualifies for Boston registration. The 736-foot net downhill gives runners a genuine speed advantage compared to flat courses — most race predictors will underestimate your finishing time on this course relative to a flat effort. Runners who've run a 3:10 on flat terrain regularly target sub-3:05 at M2B in favorable conditions.
The caveat is quad fatigue. The descent from Casitas Pass through the coast is more sustained and steep than any net-downhill BQ staple like Boston or Eugene. Runners who bank too aggressively on the downhill assistance — running faster than their calculator targets through miles 5–15 — often pay with a dead-legged last six miles that erases the downhill advantage entirely. The BQ math at M2B is real; it just requires discipline to collect.
These are the BAA's official qualifying times. Meeting the standard gets you into the registration window; actually getting in typically requires running 5–6 minutes faster than the standard based on recent cutoff history. Check baa.org for the current cycle's cutoff data.
| Age Group | Men | Women | Non-Binary |

| 35–39 | 3:05:00 | 3:35:00 | 3:35:00 |
| 40–44 | 3:10:00 | 3:40:00 | 3:40:00 |
| 45–49 | 3:20:00 | 3:50:00 | 3:50:00 |
| 50–54 | 3:25:00 | 3:55:00 | 3:55:00 |
| 55–59 | 3:35:00 | 4:05:00 | 4:05:00 |
| 60–64 | 3:50:00 | 4:20:00 | 4:20:00 |
| 65–69 | 4:05:00 | 4:35:00 | 4:35:00 |
| 70–74 | 4:20:00 | 4:50:00 | 4:50:00 |
| 75–79 | 4:35:00 | 5:05:00 | 5:05:00 |
| 80+ | 4:50:00 | 5:20:00 | 5:20:00 |
Enter your BQ target — not the qualifying standard, but the time you actually need to get in (typically 5–6 minutes faster). The calculator splits will show faster paces during the Casitas descent miles and near-neutral paces on the PCH section, reflecting the course's actual profile rather than a uniform downhill assumption.
The most common M2B BQ mistake is treating miles 5–15 as free speed and running significantly faster than target. Those miles feel easy and the physics are genuinely favorable. But 10 miles of sustained downhill running at a faster-than-target pace is a quad-destruction strategy that shows up as a catastrophic slowdown after mile 20. Your calculator splits are already optimized for the downhill — running faster than them is a bet against the physiology of descent running.
Timing note: Mountains 2 Beach runs on Memorial Day weekend in late May. A qualifier here is valid for the following April's Boston registration window — roughly a 10-month lead time, which is plenty of runway to register during September's opening window.
A point-to-point course from Ojai's mountain valley to Ventura Beach — with shuttle buses, a Memorial Day weekend atmosphere, and one of California's most scenic finish lines.
The race expo and packet pickup are typically held at the finish area in Ventura on Saturday before race day. Most runners pick up their packets Saturday and spend the afternoon off their feet in Ventura or the surrounding area. Sunday is race day — Mountains 2 Beach runs on Memorial Day weekend, which means the surrounding area is busier than a typical race weekend.
The marathon starts at approximately 6:00 AM in downtown Ojai. Half marathon starts are typically staggered by 30–60 minutes. Check the official race website for the current year's schedule as start times can vary slightly by edition.
Mountains 2 Beach is a point-to-point race, which means you cannot park at the start and walk to the finish. The race organizers run shuttle buses from the Ventura finish area to the Ojai start — this is the primary transportation method for most runners. Bus pickup begins several hours before the start.
Some runners arrange to be dropped off in Ojai by a friend or family member who drives ahead to the finish area. If you're driving to Ojai independently, confirm parking availability near the start — downtown Ojai is small and Memorial Day weekend creates additional traffic.
The start line on Ojai Avenue is one of the most picturesque in California racing — Spanish colonial architecture, arched walkways, palm trees, and the mountain backdrop visible in the predawn light. Corrals are organized by projected finish time. The start area has limited facilities compared to a city marathon, so use the shuttle pickup area restrooms before boarding if possible.
Bring a throwaway layer for the Ojai start — the mountain valley can be noticeably cooler than Ventura at 5:30–6:00 AM, even in late May. Morning temperatures in Ojai can run 10–15°F cooler than the coastal finish area on the same morning.
Aid stations are spaced roughly every two miles throughout the course. Water and sports drink are available at each station. The point-to-point nature of the course means spectator access is limited on the mountain and Casitas Pass sections — most crowd support concentrates at the start, near mile 20 on the PCH, and at the finish in Ventura.
The course is certified and monitored with regular medical support. The cutoff time is 7 hours from the marathon start. Given the net downhill nature of the course, the cutoff pace is achievable for most runners who complete long training runs consistently.
The finish is on the Ventura Beach Promenade — a wide paved walkway along the Pacific Ocean in downtown Ventura. The finish arch is set with the ocean directly behind it, making for one of the most memorable finish-line photos in California running. Post-race food, medals, and gear bag retrieval are all in the finish area along the Promenade.
Gear bags checked at the Ojai start are transported to the finish by the race organization. Plan your family meetup at a specific landmark along the Promenade — the finish area gets crowded quickly on Memorial Day weekend and cell service can be slow with everyone trying to connect at the same time.
Most runners stay in Ventura, where the finish is located. Ventura is a compact beach city with hotels ranging from national chains near the freeway to boutique options closer to the Promenade. Memorial Day weekend means elevated hotel rates and rooms that fill early — book four to six months out if possible.
Downtown Ventura parking near the finish fills on race morning. The easiest approach is staying walking distance from the Promenade finish and loading onto the shuttle to Ojai from a central pickup point. If you're driving a vehicle to the finish area, arrive early — the race attracts runners from across Southern California and the parking situation tightens significantly by 5:00 AM.
Mountains 2 Beach's 736-foot net drop puts it in a similar category to courses like Ogden (1,088 ft) and Big Sur (219 ft net downhill), but the course profile is distinct. Unlike Ogden, which has a single sustained canyon descent, M2B has an opening mountain climb followed by a long progressive descent. The initial 162-foot climb in the first three miles means you can't treat it as entirely downhill — you have to manage both the opening effort and the quad fatigue from 15+ miles of descent.
Compared to Boston (which is net downhill but has the Newton Hills), M2B is harder on your quads and easier on your aerobic system. The net drop is roughly 70% as large as Ogden's, and the overall elevation profile more closely resembles a big downhill training course than a classic race like Big Sur.
Quad fatigue from extended downhill running is the defining challenge of this course. Most race-day advice focuses on managing the opening three-mile climb, but the real problem is what happens to your legs over 15 miles of sustained descent through Casitas Pass and toward the coast. Downhill running creates significant eccentric muscle load — the kind of muscle damage that accumulates with each downhill mile and typically expresses itself as a sudden inability to run a reasonable pace somewhere after mile 20.
The best preparation is training on downhill terrain before the race and running your calculator targets on the descent rather than banking pace. Runners who successfully manage the descent consistently report that the final six miles on the PCH and into Ventura feel controlled. Runners who push the descent typically experience the opposite.
Not in the traditional sense. The opening climb in miles 1–3 means your first half will naturally be slower even with proper pacing. The "ideal" split strategy here is to run controlled through the climb, disciplined through the Casitas descent, and relatively consistent on the PCH miles — arriving at mile 23 with enough quad strength left to maintain pace through the flat Ventura finish.
The calculator's pacing strategy slider (set to Ideal or Conservative) builds this approach into your splits automatically: slightly more conservative in the early miles and slightly more credit given to the downhill miles in the Casitas section. The goal isn't negative splits — it's even effort, which looks like uneven pace because of the terrain.
The calculator uses mile-by-mile net elevation data derived from official Mountains 2 Beach course records. The uphill penalty (12–15 seconds per mile per 1% grade, user-adjustable) and downhill benefit (8 seconds per mile per 1% grade below -0.75% threshold) are based on published research on grade-adjusted pace. The math closes exactly to your goal: every target pace multiplied by its segment distance sums to your goal time.
Real performance varies with fitness, training, temperature, and fueling strategy — particularly on a downhill course where quad fatigue can cause late-race slowdowns not reflected in the elevation data. The calculator gives you the best available mathematical framework for this course; smart pacing and downhill training give you the best available physical framework to run it.
