Training for a half marathon is one of the most rewarding athletic endeavors you can take on — but weeks 8 through 12 are when most runners hit the injury wall. Mileage is at its highest, cumulative fatigue has built up, and the body is under maximum stress. At Franklin Lakes Chiropractic and Sports Medicine in Franklin Lakes, NJ, we help local runners make it to the start line healthy.


Why the Final Training Block Is the Danger Zone

The majority of training-related injuries don't happen on week one, they happen deep in the training cycle, when tissues are fatigued and the mileage climbs. You're doing long runs of 10–12 miles, adding mid-week quality work, and your body is working overtime to adapt. This is when small imbalances become big problems.


The Most Common Issues We See During Half Marathon Training

  • IT band syndrome (peaking around the 9–10 mile long run mark)
  • Stress reactions in the tibia or metatarsals
  • Hip flexor and piriformis tightness limiting stride length
  • Low back pain from accumulated compression
  • Plantar fasciitis flare-ups with increased weekly mileage


Smart Strategies for the Peak Training Block

  • Never increase your long run and weekly mileage in the same week
  • Add a true recovery week every 3–4 weeks (reduce volume by 30%)
  • Prioritize sleep. Tissue repair happens at night
  • Don't skip strength work. Hhip and glute strength is protective
  • Schedule a mid-training chiropractic check-in before symptoms become injuries
