La Jolla Half Marathon 2026: How to Train Like an Adult With a Career, Family, and Knees

The La Jolla Half Marathon is set for May 16, 2026. Coastal route, real elevation, one of my favorite events of the year.

It is also the time of year when my schedule fills up with patients nursing knee pain, plantar fasciitis, and nagging hip tightness that should have been addressed in February.

Most of the runners I see in the office did not get hurt because they ran. They got hurt because they went from occasionally active to I guess I am training now without a plan.

Reasons to Run

Before the strategy, the reasons. Running, when you build into it intelligently, is one of the highest-return things an adult can do for long-term health.

It strengthens your cardiovascular system in ways no other activity replicates at the same time investment. It improves insulin sensitivity, which matters more than most people realize, especially for executives sitting through long meetings and traveling on airplane food. It builds bone density. It regulates sleep. It clears your head.

For my patients with families, training for a half marathon often becomes the first time in years they have committed to a goal that is just for them. That alone is worth something.

The Sane-Person Training Strategy

Increase your mileage slowly. Your cardiovascular system adapts faster than your tendons and joints, which is why so many runners feel great in week three and break down in week six. No more than a 10 percent jump in weekly mileage, and even that can be aggressive for someone returning to running after years off.

Protect your sleep the way you protect your training. Sleep is when adaptation happens.

Fuel before your long runs. Underfueling is not discipline. It is a recipe for muscle breakdown and a long run that ends with you bonking at mile nine.

Practice hydration before race day. Race day is not the morning to figure out which sports drink your stomach can handle.

Strength train. Hips, calves, glutes, and core. Twice a week is enough. The runners who skip strength work are the same ones I see in clinic with IT band syndrome or stress fractures.

Respect any pain that changes how you walk or run. Pushing through a sore quad is one thing. Pushing through pain that makes you limp is how you turn a six-week issue into a six-month one.

The Three Mistakes I See Every Spring

The weekend-warrior overload. Five sedentary days, then a 12-mile run on Saturday. The body cannot absorb that load.

Ignoring recovery. No stretching, no mobility, poor sleep, no rest days. Recovery is where fitness is built.

Not adjusting for heat and sun. Spring into summer in coastal San Diego is deceptively rough. Marine layer in the morning, then full sun by mid-run. Time your runs early, hydrate steadily through the day, and do not skip sunscreen because you think the clouds are protecting you. They are not.

When to Call Your Physician

Some symptoms are normal in training. Sore quads, tight calves, the occasional bad run. These are different:

• Chest discomfort

• Shortness of breath disproportionate to your effort

• Palpitations or an irregular heartbeat

• Lightheadedness or near-fainting

• Swelling in the legs or ankles

• Persistent knee, Achilles, or plantar pain that does not resolve with rest

Catching a cardiac issue or a stress fracture early is the difference between a small adjustment and a serious problem.

A Practical Race-Week Plan

Two nights before, prioritize sleep. The night before, you may sleep poorly from nerves, so the night before that is the one that counts.

The day before, hydrate steadily. Skip the 1998-style pasta binge. A normal balanced dinner is enough.

Race morning, eat a light meal you have tested in training. Wear shoes you have run in for at least 50 miles. Sunscreen. Nothing new.

After the race, focus on protein, fluids, and a slow recovery walk.

The Executive Health Angle

For most of my patients, performance is not about a medal. It is about being fit enough to keep up with their kids, travel without feeling wrecked, work at a high level, and age well.

This is where concierge medicine changes the equation. We can screen cardiovascular risk before training begins, interpret early symptoms during the build-up, and adjust your plan around travel weeks and work stress. When something feels off, you can reach me directly instead of waiting six weeks for an appointment.

A half marathon is not a stress test. It is a result. The work happens in the months before.

The Quick Recap

• Train progressively

• Sleep more, not less

• Fuel and hydrate intelligently

• Wear SPF 30 or higher outdoors and reapply

• Get evaluated early if symptoms feel off

The goal is not just finishing the La Jolla Half. The goal is finishing strong, staying healthy, and not limping through meetings for the next two weeks.
