Miami Marathon Training: A Plan to Reach the Start Healthy

Miami Marathon training works best as four phases across 12 weeks: three weeks of base running, three of build, three of peak, then a three-week taper, with two strength sessions per week and a lighter week roughly every fourth week. The 2027 Life Time Miami Marathon & Half is scheduled for Sunday, January 31, 2027, with the Tropical 5K on Saturday, January 30, according to the official race site, so 12 weeks out lands in early November. Check that site for current entry status. This structure assumes you already run a few times a week; if you do not, start earlier or choose the half marathon, and read how to build running mileage safely first.

This is a framework, not a prescription. It cannot account for your injury history, your pace or your schedule, and no plan prevents every injury. What it can do is keep the common causes of marathon injuries, mainly sudden jumps in load and no strength work, off the table.

The 12-week structure at a glance

The plan below uses effort and general mileage direction rather than exact numbers, because the right numbers depend on what you are running now. Start from your current weekly mileage and your current longest run, not from a template's week one.

A lighter week usually means cutting weekly volume by roughly a quarter to a third while keeping the same number of run days. Many runners skip them because they feel fine, which is when the lighter week does its job.

A sample week during the build phase

An example layout for a runner doing four runs a week:

• Monday: Strength session (squat or leg press pattern, hip hinge, single-leg step-ups, calf raises, core carry).
• Tuesday: Easy run, conversational pace.
• Wednesday: Rest or easy cross-training such as cycling.
• Thursday: Run with a controlled faster section.
• Friday: Strength session, slightly shorter than Monday.
• Saturday: Easy short run or rest.
• Sunday: Long run, early, at easy effort.

Keep at least one full day between hard runs and the heavy leg session. If your long run is Sunday, leave Saturday easy and avoid your hardest lifting on Friday.

Strength training for Miami marathon training

Strength work in marathon training means two short sessions a week built around a few movements, and it matters because running loads the same tendons and joints thousands of times per run. A reasonable starting point:

1. Squat or leg press: 3 sets of 6 to 8 reps.
2. Romanian deadlift or hip hinge: 3 sets of 6 to 8 reps.
3. Single-leg step-up or split squat: 3 sets of 8 reps per side.
4. Straight-knee and bent-knee calf raises: 3 sets of 10 to 15 reps, slow tempo.
5. Side plank or suitcase carry: 2 to 3 sets of 20 to 40 seconds per side.

Choose weights where the last two reps are hard but your form holds. Heavy, slow calf and single-leg work is especially relevant to the Achilles, shin and knee problems below. If you have never lifted, a coach can set loads and technique in a couple of sessions, which is where performance training fits in.

Injuries marathon training tends to produce

Marathon injuries cluster in a handful of places, and most start as small aches that get ignored for a few weeks. Each one has its own post:

• Shin pain along the inner edge of the shin: see shin splints in runners.
• Heel or arch pain, worst with first steps in the morning: see plantar fasciitis exercises.
• Pain in the back of the ankle or just above the heel: see the Achilles tendon rehab plan.
• Pain on the outside of the knee: see IT band syndrome.
• Pain around or behind the kneecap, especially on stairs and downhills: see runner's knee.

The underlying cause is usually load rising faster than tissue can adapt, which is the subject of load management explained. Footwear changes or a sudden hill block can do the same.

What to do when something flares

A flare-up needs a response proportionate to the symptom, not automatic rest and not automatic pushing through. Use this decision list:

1. Mild ache that settles in minutes and is gone the next morning: keep running, shorten the next run slightly and check whether you changed shoes, surface or mileage.
2. Ache that appears every run and lingers into the evening: cut the long run and any faster work for a week, keep easy running only if it stays low, and add the relevant strength exercise. Our post on when to modify versus stop marathon training covers the pain-scale rule in detail.
3. Pain that changes how you run, such as a limp or altered stride: stop running that day and book an evaluation before the next run.
4. Pain that does not improve after a week of lighter training: get it assessed rather than waiting for the next lighter week.

Get prompt evaluation for sharp or worsening pain, pain at night, swelling, numbness, pain on one spot of a bone, or inability to bear weight. Stop and seek urgent help for chest pain, fainting, confusion or signs of heat illness. For Miami-specific heat advice, see our post on running in Miami heat and humidity.

What this plan cannot do

A structure like this cannot replace individual assessment. If you have had a recent injury, a stress fracture, a heart or lung condition, or you are returning from surgery, talk with your clinician before committing to a marathon block. A physical therapist can look at how you move, test calf, hip and single-leg strength, and adjust the plan. We work with runners at our South Miami and Wynwood locations, and physical therapy is the right starting point if something already hurts.

Frequently asked questions

How many days a week should I run for Miami Marathon training?

Many runners do well with three to five run days a week, depending on experience and injury history. Fewer, well-spaced runs plus strength work often beat more days of tired running. Pick a number you can sustain through the peak weeks.

Should I lift during the peak and taper phases?

Generally yes, with lower volume. Keep the weights moderate and the sessions short, and avoid new exercises in the last two weeks, since unfamiliar soreness can disrupt race preparation. The taper itself is covered in our Miami Marathon taper and race week plan.

What if I miss a week of training?

Do not stack missed mileage onto the next week. Resume near the level before the gap, or slightly below if you were ill or injured. One missed week rarely changes race-day fitness; making it up often causes the injury you were avoiding.

If you want a second set of eyes before your build phase starts, book an evaluation and we will look at your running history, strength and any aches you have been tolerating.
