How to Train the Week of a Half Marathon: Your 7-Day Plan
Introduction
Did you know that in the final seven days before your half marathon, you can’t actually do anything to get physically "fitter" for the race, but you can certainly do things that might jeopardize your performance? It sounds a bit startling, but it is the golden rule of tapering. You have spent weeks—perhaps months—putting in the miles, sweating through intervals, and building the mental grit required to tackle 13.1 miles. Now, the final week is all about "priming the engine" rather than "building the machine."
The purpose of this guide is to walk you through exactly how to train the week of a half marathon, whether you are a first-timer just looking to cross the finish line or a seasoned racer aiming for a personal best. We will cover the physiological reasons for tapering, a day-by-day workout schedule for different skill levels, nutrition and hydration protocols, and the essential logistics that remove stress before the starting gun goes off.
At Sport2Gether, we believe that the journey to the finish line is always better when shared. That is why we focus so much on the community aspect of training. Even in this final "taper" week, staying connected with your running community can help calm the nerves and keep you focused. Our main message is simple: trust the work you have already done, keep your legs moving without overtaxing them, and prioritize recovery so you arrive at the start line feeling like a coiled spring, ready to fly.
The Science and Psychology of the Taper
Before we dive into the daily schedule, it is important to understand why we reduce our mileage. This period is known as the "taper." When you train hard, you are constantly breaking down muscle fibers and taxing your central nervous system. A proper taper allows your body to repair those micro-tears, restock its glycogen (energy) stores, and find its natural rhythm.
Physiological Restoration
During your peak training weeks, your body is in a state of constant recovery. By cutting your mileage by about 30% to 50% in the final week, you allow your red blood cell mass and hemoglobin levels to reach their peak. This means your blood can carry oxygen to your muscles more efficiently on race day.
The "Taper Crazies"
Psychologically, the final week can be difficult. Many runners experience what we call the "taper crazies"—a feeling of restlessness, phantom pains in the legs, or the sudden fear that you’ve lost all your fitness. We want you to know that this is completely normal! If your knee suddenly feels a bit "tweak-y" on a Tuesday afternoon when you aren't even running, it is likely just your brain processing the upcoming challenge. Staying connected with others through our app can help you realize that everyone else is feeling the same way.
Nutrition and Hydration Strategies
You might have heard about "carb-loading," a practice often associated with the full marathon. For a half marathon, you don't necessarily need to drastically increase your calories, but you do need to be intentional about where those calories come from.
Focusing on Carbohydrates
Three days before the race, start shifting your plate to be more carbohydrate-heavy. Think of easy-to-digest options like white rice, pasta, potatoes, and oats. These are your body’s primary fuel source. We suggest avoiding high-fiber foods (like large salads or beans) starting 48 hours before the race to prevent any digestive "surprises" on the course.
Hydration and Electrolytes
Hydration isn't just about drinking water on the morning of the race. It’s a week-long process. Aim to carry a water bottle with you throughout the day. Adding electrolytes can be incredibly helpful, especially if you are a "salty sweater" or if the forecast looks warm. We recommend arriving at the start line "pre-hydrated"—your urine should be a light straw color, not crystal clear (which can indicate over-hydration and mineral imbalance).
Pre-Race Breakfast
Never try a new breakfast on race day. Use the meals you ate before your longest training runs as your guide. Whether it’s a bagel with peanut butter or a bowl of oatmeal with a banana, stick to the tried-and-true.
The Beginner’s Final Week Breakdown
If this is your first half marathon, your goal is to stay loose and build confidence. You don't need to do anything heroic this week.
Monday: The Maintenance Run
Start the week with a short, easy run of 20 to 40 minutes. The pace should be very relaxed—you should be able to hold a full conversation. At the end of the run, perform 4 "strides." A stride is a 100-meter acceleration where you gradually build up to about 90% of your max speed and then decelerate. This keeps your fast-twitch muscles awake without causing fatigue.
Tuesday: Rest and Mobility
Take today off or engage in very light movement. Gentle yoga or a 20-minute walk is perfect. Use this time to check the "Events" or "Hotspots" in our app to see if there are any local groups meeting for a post-race celebration.
Wednesday: The Confidence Booster
Run for 30 minutes in total. After a 10-minute warm-up, do 5 sets of 2 minutes at your "goal race pace" with a 1-minute walking break in between. This isn't a hard workout; it’s just to help your brain and body remember what that pace feels like. Follow it with a 10-minute cool-down.
Thursday: Total Recovery
Today is a great day for a nap or a movie. Avoid spending hours on your feet shopping or sightseeing. Rest is productive work this week!
Friday: Short Shakeout or Rest
You can either rest or do a very short 15-minute jog just to settle your nerves. Focus on eating a good, carb-rich dinner and getting to bed early.
Saturday: The Eve of the Race
If you feel restless, a 10-minute walk or a 15-minute "shakeout" run can help. Lay out your gear (your "flat runner") so you aren't searching for socks at 5:00 AM.
Sunday: Race Day!
Give yourself plenty of time to get to the start. Do a very light 5-minute walk/jog to get the blood flowing, and remember: you are here to have fun!
The Experienced Runner’s Performance Week
For those chasing a specific time, the week looks slightly different. We keep the intensity but drop the volume significantly.
Monday: Easy Volume + Strides
A 40-minute easy run. Include 5-6 strides at the end to keep the legs "snappy." Focus on your form—head up, shoulders relaxed.
Tuesday: The Sharpness Session
This is your last "workout." It should feel short and fast.
- 15-minute warm-up.
- 3 x 1km at your half marathon goal pace (or slightly faster) with a 2-minute recovery jog.
- 10-minute cool-down. The goal here is to feel "pop" in your legs, not to finish feeling exhausted.
Wednesday: Recovery or Light Cross-Training
A 30-minute very easy recovery run or some light cycling. If you are feeling any specific tightness, consider using the chat feature in our community to ask for local physical therapist recommendations or recovery tips.
Thursday: Race Pace Touch
Run for 30 minutes total. Include two 5-minute segments at race pace to dial in your rhythm. This ensures your "internal clock" is ready for Sunday.
Friday: Rest Day
Focus on high-quality sleep. Interestingly, the sleep you get two nights before the race (Friday night) is often more important for performance than the sleep you get the night immediately before the race, which is often interrupted by nerves.
Saturday: The Shakeout
We recommend a 20-minute very easy jog with 3 short strides. This "primes" the neuromuscular system so you don't feel sluggish when the race starts.
Sunday: Race Day!
Arrive early, find your pacing group, and execute the plan you have practiced for weeks.
Gear Readiness and The "Nothing New" Rule
The most important rule in running is: Nothing new on race day. This applies to everything from your socks to your energy gels.
- Shoes: Do not wear brand-new shoes that you haven't run in. Your race shoes should have at least 20–50 miles on them so they are broken in but still have plenty of "bounce."
- Clothing: Check for seams that might cause chafing. Use anti-chafe balm liberally on any areas of friction.
- Technology: Charge your watch, your headphones, and your phone. If you use a heart rate monitor, ensure the battery is fresh.
- Weather Prep: Check the forecast daily. If there is a chance of rain, bring a disposable poncho or a trash bag to stay dry while waiting in the starting corral. If it’s cold, wear "throwaway" clothes from a thrift store that you can discard after the first mile (most races collect and donate these).
Race Logistics and Mental Readiness
Stress is a performance killer. By handling your logistics early in the week, you free up mental energy for the race itself.
Packet Pickup
Try to pick up your race bib and packet as early as possible. If the expo is on Friday and Saturday, go on Friday to avoid the massive crowds on Saturday. This keeps you off your feet.
Course Study
Look at the elevation profile of the race. Are the hills in the first few miles or the last few? Knowing where the challenges are allows you to pace yourself effectively. We often see our users discussing course specificities in the app—don't be afraid to ask others who have run the course before for their advice!
Visualization
Spend 10 minutes each evening visualizing the race. Imagine yourself hitting the 10-mile mark—the "dead zone" of a half marathon—and feeling strong. Visualize crossing the finish line with a smile. Mental rehearsal is a powerful tool used by elite athletes to maintain composure when things get tough.
Building Community with Sport2Gether
One of the biggest hurdles to staying consistent is the feeling of being alone in your goals. At Sport2Gether, we’ve built a platform that removes that barrier.
In the week leading up to your race, you can use the map feature to find "Hotspots" where other runners are doing their final shakeout runs. It is much easier to keep a "recovery pace" when you are chatting with a friend than when you are running alone and accidentally pushing too hard.
If you are a trainer or a club leader, our Premium tools allow you to promote your race-week meetups, manage attendance, and even coordinate transport for your members. We believe that "Together is better," and there is no better time to experience that than the week of a big event. Whether you need a pep talk or someone to share a post-race carb-heavy meal with, the community is there to support you.
Safety and Professional Advice
While we want you to push your limits and discover what you’re capable of, your health is the top priority. Please listen to your body. If you feel a sharp, localized pain during your taper week, it is better to rest entirely than to push through and risk a long-term injury.
Disclaimer: This guide provides general fitness information and is not a substitute for professional medical advice. Always consult with a healthcare professional or a certified coach before starting a new exercise program or significantly changing your training intensity. Exercise within your physical limits, and if you experience chest pain, dizziness, or extreme shortness of breath, stop immediately and seek medical attention.

FAQ
Q: Should I lift weights during the final week of a half marathon?
A: Generally, we recommend skipping heavy strength training in the final seven days. You want your muscles to be fully recovered and free of soreness. If you feel the need to move, stick to very light bodyweight mobility or stretching.
Q: What should I do if I miss a run during the final week?
A: Don't panic! Missing a 20-minute easy run on a Tuesday will have zero negative impact on your race performance. In fact, the extra rest might even help. Never try to "make up" for a missed run by doing double the mileage the next day during a taper.
Q: How much water should I drink on the morning of the race?
A: Aim for about 16–20 ounces of water or an electrolyte drink two to three hours before the start. This gives your body time to process the fluid. Stop drinking about 30–45 minutes before the gun goes off to avoid having to find a restroom in the middle of the race.
Q: Is it okay to run a 5K race the day before my half marathon?
A: For most runners, a 5K race the day before is too much intensity. While some experienced runners use it as a "shakeout," it can deplete your glycogen stores and leave your legs heavy. We suggest a very light 15-minute jog or a walk instead.
Training for a half marathon is an incredible accomplishment, and the final week is your time to shine. By following a structured plan, focusing on recovery, and leaning on your community, you’ll be ready to tackle those 13.1 miles with confidence.
