If you have registered for a Run Project half marathon — or you are circling the Skyline Half Marathon, Badass Texas, or Too Hot To Handle on your calendar — you need a plan that respects both the distance and the Texas climate. A half marathon is a serious but achievable goal for most healthy adults. With twelve structured weeks, sensible progression, and race-day habits that match North Texas weather, you can arrive at the start line confident rather than guessing.
This guide is a complete half marathon training plan written for runners in Dallas, Fort Worth, and the broader DFW metro. It includes weekly structure, sample mileage, taper guidance, hydration strategy for heat, and a race-day checklist. Use it alongside your Run Project registration and, if you are running multiple events, consider building a Series Pass so your training season maps cleanly to your race calendar.
Who this half marathon training plan is for
This plan assumes you can currently run or run-walk for thirty minutes without stopping. You do not need a marathon background. You do need consistency, reasonable footwear, and the willingness to adjust pace when Dallas-Fort Worth throws you a ninety-degree morning or a surprise cold front in January.
The plan works for:
- First-time half marathoners targeting a Run Project 13.1-mile event
- Experienced 10K runners stepping up in distance
- Runners returning after time off who want a conservative rebuild
- Athletes using a half as a tune-up before a longer goal later in the year
If you have a medical condition, recent injury, or cardiovascular history, clear training with your physician before beginning. This article is coaching education, not medical advice.
Twelve-week overview: three phases
Most successful half marathon training blocks split into base building, volume progression, and taper. The table below summarizes the arc. Exact mileage will vary by starting fitness; the principles matter more than hitting a number perfectly every week.
| Phase | Weeks | Focus | Weekly runs | Long run target |
|---|---|---|---|---|
| Base | 1–4 | Aerobic foundation, form, habit | 3–4 | 6 → 9 miles |
| Build | 5–9 | Endurance, race-pace touches | 4–5 | 10 → 12 miles |
| Peak & taper | 10–12 | Confidence, freshness | 3–4 | 12 → 8 → race |
Count backward from your race date. If Skyline is your target, block twelve weeks on the calendar and treat weeks ten through twelve as non-negotiable taper territory even if life gets busy earlier in the cycle.
Phase 1: Base building (weeks 1–4)
Weekly structure
Run three or four days per week. Separate your runs with at least one rest day or easy cross-training day. A typical week might look like:
- Tuesday: Easy run 30–40 minutes at conversational pace
- Thursday: Easy run with 4–6 short strides (20 seconds fast, 60 seconds easy) OR a steady 35-minute run
- Saturday or Sunday: Long run, starting around 5–6 miles and adding roughly one mile per week
- Optional: Second easy day (20–30 minutes) or brisk walk, bike, or swim
Pace and effort
During base phase, almost everything is easy. If you cannot speak in full sentences, you are running too fast for a standard easy day. North Texas humidity makes easy pace slower than your ego prefers. Accept that. Training by effort protects you when heat index spikes in late spring or early fall.
Strength and mobility
Twice per week, add fifteen minutes of runner-focused strength: glute bridges, calf raises, side planks, and hip flexor stretches. Half marathon training is high repetition; weak hips and tight calves are how shin splints enter the chat. You do not need a gym membership — consistency beats complexity.
Week 4 checkpoint
By the end of week four, you should complete a long run of eight to nine miles feeling tired but not destroyed. If you are short of that, extend base one more week before pushing build-phase volume. There is no prize for rushing into fatigue.
Phase 2: Build (weeks 5–9)
Adding volume safely
Increase total weekly mileage by no more than ten percent week over week. Your long run grows toward eleven or twelve miles. Midweek runs can extend to forty-five or fifty minutes. One weekly run may include controlled tempo work: after a fifteen-minute warm-up, run fifteen to twenty minutes at a pace you could hold for roughly an hour — often called “comfortably hard” — then cool down.
Simulating race conditions
If your target is a September or spring Dallas race, practice at least two long runs in weather similar to race morning. For Too Hot To Handle, that means early starts, hydration belts or planned water stops, and electrolytes. For Too Cold To Hold, layer intentionally and practice what you will shed after mile two.
10K tune-up option
Week seven or eight is an ideal window for a 10K race or time trial. Run Project hosts multiple 10K distances across the calendar — Melon Dash and several Dallas events fit well. Racing a 10K gives you a fitness benchmark and rehearses nerves, parking, and pre-dawn logistics without the full half marathon cost.
Recovery discipline
Build phase is where runners overreach. Protect sleep, fuel within sixty minutes after long runs, and keep easy days truly easy. If a week feels flat, drop one run rather than pushing through sharp pain. A missed workout is training data; a stress fracture is a season.
Phase 3: Peak and taper (weeks 10–12)
Peak week
Week ten is typically your longest long run — often eleven to twelve miles for first-time half marathoners. Run it steady, not heroic. Practice your race-morning breakfast, shoes, socks, and fueling strategy. Note what chafes. Fix it before race day.
Taper weeks eleven and twelve
Reduce volume by twenty to thirty percent in week eleven and forty to fifty percent in race week. Maintain a little intensity — a few short pickups — so your legs feel springy. Many runners panic during taper and add extra miles. Do not. Trust the work you banked in weeks five through ten.
Race week habits
- Sleep eight hours; start banking sleep two nights before if race eve is restless
- Hydrate with electrolytes if forecast is warm; do not chug plain water only
- Walk through packet pickup early; know parking and corral placement
- Lay out bib, pins, outfit, and post-race layer the night before
Texas-specific training considerations
DFW is not flat like a Midwest rail trail, and it is not cool like a coastal morning in November. Your plan must account for:
Heat and humidity
From May through September, schedule key workouts at dawn. Wear light colors, visors, and sunscreen. On long runs over seventy-five degrees, carry fluid or plan loops past water fountains. Pace by heart rate or perceived effort, not winter PR splits. Our guide to running in Texas summer heat goes deeper on hydration and pacing adjustments.
Wind and open courses
Many Run Project courses use urban parks and lakefront paths where wind matters. Practice running into a headwind for segments of your long run — it builds mental toughness and teaches even pacing when the second half feels harder than the first.
Trail and path options for training
Dallas-area runners often train on Katy Trail, White Rock Lake loops, and suburban path networks in Plano and Frisco. Fort Worth athletes use Trinity Trails. Vary surface when possible to reduce repetitive stress, but prioritize specificity as race day approaches — if your event is road, bias toward road long runs in the final four weeks.
Sample week at peak build (week 9)
| Day | Workout | Notes |
|---|---|---|
| Mon | Rest or 30-min walk | Mobility, foam roll |
| Tue | 45 min easy | Conversational pace |
| Wed | Strength 20 min + 25 min easy | Glutes, calves, core |
| Thu | Tempo: 15 w/u, 20 tempo, 10 c/d | Controlled, not sprinting |
| Fri | Rest | Sleep priority |
| Sat | 11-mile long run | Practice fuel + hydration |
| Sun | 30 min easy or off | Listen to legs |
Fueling and hydration for long runs
For runs under seventy-five minutes, water is usually enough. Beyond that, most runners benefit from thirty to sixty grams of carbohydrate per hour — gels, chews, or real food you have tested in training. Never experiment on race morning. Salt tabs or electrolyte drink mix help when sweat rate is high, which is most Texas long runs from June onward.
Post-run, eat protein and carbs within the first hour. Chocolate milk, a turkey sandwich, or a balanced meal works. Half marathon training increases appetite; fuel recovery deliberately instead of treating extra hunger as a mistake.
Injury prevention and when to back off
Sharp pain, pain that changes your gait, or pain that worsens as you run means stop and assess. Common issues — IT band tightness, plantar discomfort, shin soreness — often respond to rest, ice, and professional evaluation if they persist more than a few days. Substitute pool running or cycling to maintain fitness without loading irritated tissue.
Replace running shoes every three hundred to five hundred miles. Log miles in a notes app so you are not guessing. Rotate two pairs if budget allows — shoes need twenty-four hours to decompress between runs.
Race day strategy for Run Project half marathons
Run Project events use professional chip timing and organized corrals. Arrive early, use the restroom line that looks longest (it moves), and start conservatively. The first mile should feel almost too easy. Half marathons are won in patience: runners who surge early often walk late.
Negative split — second half slightly faster than first — is a realistic goal on well-managed courses. Use aid stations even if you are not thirsty. Thank volunteers. Save one gear for the final 5K when others fade.
After you finish, walk, hydrate, and eat. Collect your medal, find your people, and note one thing to improve next cycle. Many runners in DFW treat the half marathon calendar as a year-long rhythm; your next start line might be only twelve weeks away.
Pair your training with the right race
Choosing the right event keeps motivation high. Dallas runners often anchor around Skyline. Athletes who want a spring half with a strong community field look at Badass Texas in Waco. Heat-trained runners target Too Hot To Handle. Browse the full race calendar or our Dallas running races hub to match your training timeline to a date that fits your life.
If you plan to run two or more events in a season, a Series Pass reduces per-race cost and locks in entries before popular distances sell out. That financial commitment is also a psychological one — you are less likely to skip long runs when the calendar is already paid for.
Mental training and goal setting
Half marathon preparation is as much cognitive as physical. Most DNF stories in local races are not fitness failures — they are pacing failures, anxiety spirals, or unprepared race-morning logistics. Set three goals before week one: an outcome goal (finish strong), a process goal (complete ninety percent of planned runs), and a contingency goal (what you will do if weather or life disrupts a key workout).
Visualization helps. Once per week during build phase, spend five minutes imagining race morning: alarm, breakfast, drive, corral nerves, first mile calm, aid stations, final 5K effort, finish arch. Athletes who rehearse logistics mentally report lower stress on actual race day. Pair visualization with concrete planning — pin your parking map, save the packet pickup email, and add the race to your calendar with a two-hour pre-start alert.
Mantras are not cheesy when they work. Short phrases — “smooth and steady,” “this is what I trained for,” “the next aid station” — give your brain something to repeat when discomfort arrives at mile ten. Write one on your hand or wristband if that helps.
Final thoughts
A half marathon training plan is not magic. It is repeated easy miles, a handful of purposeful hard sessions, long runs that teach patience, and a taper that lets fitness express itself. Texas adds heat, wind, and occasionally glorious fifty-degree race mornings — adapt accordingly. Twelve weeks from now, you can cross a Run Project finish line knowing you prepared with intention.
