Steps
1. Build a Baseline
Complete a 5K or 10K test run at comfortable pace to establish starting mileage and fitness level.
2. Design Your Schedule
Follow a 12-week plan with three run days per week: easy runs, one long run, and one speed or tempo session, increasing weekly volume by no more than 10%.
3. Incorporate Strength and Mobility
Add two weekly strength sessions focusing on core, hips, and legs plus daily mobility work to support running form.
4. Practice Race Nutrition
Test fueling strategies on long runs of 10+ miles using the same gels and hydration you plan to use on race day.
5. Taper and Recover
Reduce mileage by 20-30% in the final two weeks before the race while maintaining short easy runs and prioritizing sleep.
6. Review and Adjust
Track how your body responds each week and modify the plan if signs of overtraining appear.
Tips
- Prioritize sleep and rest days
- Run with a training partner for accountability
- Replace shoes every 300-500 miles
- Include cross-training like cycling on non-run days
