Surviving a Treadmill Half Marathon
- Nutrition plan: Take gels or fuel every 45 minutes during the run
- Hydration: Sip water every 10-15 minutes — have bottles pre-filled
- Mental breaks: Divide the run into 3-4 segments mentally rather than thinking about 13.1 miles
- Vary incline slightly: Small 0.5-1% changes every few miles reduce repetitive strain
- Music or entertainment: Essential for 2+ hours on a treadmill
