Running Training Plan Builder

Build a complete running training plan based on the following runner profile:

Target Race Distance: [5K/10K/HALF MARATHON/MARATHON/ULTRAMARATHON/NO RACE JUST FITNESS]
Current Running Level: [COMPLETE BEGINNER/CASUAL JOGGER/RECREATIONAL RUNNER/COMPETITIVE RUNNER]
Current Weekly Mileage: [0-10/10-20/20-30/30-40/40+ MILES PER WEEK]
Race Goal: [JUST FINISH/SPECIFIC TIME TARGET/PR ATTEMPT/PODIUM COMPETITIVE]
Available Training Days: [3/4/5/6 DAYS PER WEEK]
Time Until Race: [8/12/16/20/24 WEEKS]
Injury History: [NONE/SHIN SPLINTS/KNEE ISSUES/PLANTAR FASCIITIS/IT BAND/OTHER]

Develop the training plan across these six sections:

1. Baseline Assessment & Race Strategy
Evaluate the runner's current fitness level and establish appropriate training paces. Use recent race times or a time trial to estimate current VO2max and calculate training zones: easy or conversational pace for zone 1 and zone 2, tempo or comfortably hard pace for zone 3, interval or hard pace for zone 4, and repetition or very hard pace for zone 5. Provide these paces in both minutes per mile and minutes per kilometer. If the runner has no recent race data, provide a protocol for a 1-mile or 1.5-mile time trial to establish baseline paces. Outline the race day strategy including target pace per mile or kilometer, pacing strategy for negative or even splits, fueling plan during the race, and mental checkpoints. Set intermediate milestones to check training progress at weeks 4, 8, and 12.

2. Weekly Training Structure & Key Workouts
Design the week-by-week training plan with specific daily workouts for the entire program duration. Each week should include a long run with progressive distance increases following the 10 percent rule, one speed or interval session building from strides and fartleks to structured intervals and tempo runs, one moderate-effort steady-state run, easy recovery runs on remaining days, and one designated rest day minimum. For each key workout, specify the exact distance or duration, target pace or heart rate zone, warm-up and cool-down protocols, and the physiological purpose of the session. Include a 2 to 3 week taper period before race day with specific mileage reduction percentages of 60 to 75 percent of peak volume while maintaining some intensity.

3. Pace & Effort Guide
Provide a detailed pace chart for every workout type in the plan. Break down easy runs at 60 to 70 percent of max heart rate with conversation pace guidelines. Define long run pace as easy pace to easy plus 15 seconds per mile. Specify tempo run pace as the pace you could sustain for about 60 minutes in a race. Detail interval paces for 400-meter, 800-meter, 1000-meter, and mile repeats with appropriate recovery jog durations between repeats. Include rate of perceived exertion equivalents on a 1 to 10 scale for runners without GPS watches or heart rate monitors. Provide guidance on adjusting paces for heat adding 15 to 30 seconds per mile above 65 degrees Fahrenheit, humidity, altitude adding 5 to 10 seconds per mile per 1000 feet above 3000 feet, and wind conditions.

4. Cross-Training & Strength Work
Design complementary training to support running performance and prevent injury. Provide a runner-specific strength routine performed 2 to 3 times per week lasting 20 to 30 minutes covering single-leg exercises like lunges, step-ups, and single-leg deadlifts, hip stability work including clamshells, side-lying leg raises, and monster walks, core work covering planks, dead bugs, bird dogs, and pallof press, and calf and foot strengthening with heel raises, toe spreads, and arch doming. Include a mobility and stretching protocol targeting hip flexors, hamstrings, calves, IT band, and thoracic spine. Recommend cross-training options for non-running days ranked by specificity: cycling, swimming, elliptical, rowing, and yoga. Explain when to replace a running day with cross-training versus adding it on top of running volume.

5. Injury Prevention & Management
Address the most common running injuries with prevention protocols. Cover shin splints through gradual mileage progression and calf strengthening. Address runner's knee with quad strengthening and foam rolling of the IT band and quads. Discuss plantar fasciitis prevention with calf stretching, foot strengthening, and appropriate footwear. Include Achilles tendinopathy prevention through eccentric heel drops and proper warm-up. Provide a pre-run dynamic warm-up routine lasting 5 to 8 minutes with leg swings, walking lunges, high knees, butt kicks, and A-skips. Include a post-run routine with static stretching and foam rolling lasting 5 to 10 minutes. Provide a traffic light system: green means train as planned, yellow means modify the workout by reducing intensity or volume, and red means take a rest day and consider professional evaluation. Include guidelines on when to run through discomfort versus when to stop.

6. Race Day Preparation & Execution
Provide a complete race day playbook. Cover the final week including carbohydrate loading strategy for half marathon distance and above, sleep optimization, equipment checklist, and race kit layout. Detail race morning timing from wake-up to the starting line including pre-race meal consumed 2 to 3 hours before with specific food suggestions, warm-up jog and dynamic stretches 20 to 30 minutes before, and mental preparation techniques. Provide mile-by-mile or kilometer-by-kilometer race execution strategy with pacing guidance, mental cue words, and fueling timing. Address common race day problems including side stitches, hitting the wall, bathroom needs, and weather adjustments. Include post-race recovery protocol for the first 48 hours and the first 2 weeks covering nutrition, gentle movement, and when to resume structured training.
