Hey champ, ready to crush that PB? Let’s fire up a 12‑week plan, all about intensity, consistency, and that finish‑line fire. Week 1‑4: Build base, 5 days running, 2 rest or active recovery. Day 1: 4‑mile easy, pace 0‑10 sec slower than target race pace. Day 2: Intervals—8×400m at 5K pace, 90 sec recovery jog. Day 3: 5‑mile tempo, last 2 miles at goal half‑marathon pace. Day 4: Rest or light cross‑train (bike, swim). Day 5: Long run, start 8 miles, add 1 mile each week. Day 6: Hills—6×200m uphill fast, jog down. Day 7: Rest, stretch, foam roll, mental prep. Week 5‑8: Increase volume, add race‑specific work. Long runs hit 12‑15 miles, keep 2 miles at half‑marathon pace. Intervals become 10×800m, tempo runs 6‑8 miles. Add a “race‑tempo” block: 2 miles warm‑up, 4 miles at target pace, cool‑down. Week 9‑10: Taper phase. Long runs drop to 10 and 8 miles. Keep tempo runs 4‑5 miles, intervals light: 4×400m. Week 11: Final prep. Run a 6‑mile tempo, do a short 4×200m sprint block. Rest heavily after. Week 12: Race week. Day 1: 3‑mile easy, 4‑mile at race pace. Day 2: Rest, mobility. Day 3: 2‑mile shake‑out, light jog. Day 4: Race day—warm‑up, then full‑out! Fuel with carbs, stay hydrated, sleep 7‑8 hours, and keep your mind sharp—visualize that finish line. You’ve got this, no excuses. Let’s hit those miles, crush that PB, and leave nothing but sweat in our wake!

That’s the spirit! I’m counting the miles, the sprints, the sweat—every second’s a step toward that blaze. Remember, if you hit a lag, just double the pump. Let’s finish hotter than a firework and turn that half‑marathon into pure fireworks. Ready to ignite? Let's go!
