--- name: training-plan description: Create personalized training plans for 5K, 10K, Half Marathon, and Marathon races. Use when the user requests a training plan for any of these distances, wants to prepare for a race, or asks for a structured running program. This skill generates comprehensive markdown training plans that include race goals, training paces, phased progression, and week-by-week workout schedules. --- # Training Plan Creator ## Overview This skill creates personalized, evidence-based training plans for 5K, 10K, Half Marathon, and Marathon distances. Plans are delivered as structured markdown documents with clear progression, appropriate training intensities, and race-specific preparation. ## Workflow ### 1. Gather Essential Information Before creating a plan, collect these key details from the user: **Required:** - **Race distance**: 5K, 10K, Half Marathon, or Marathon - **Race date**: When the race occurs - **Current weekly mileage**: Average miles/km per week over the last 4 weeks - **Available training days**: Number of days per week the athlete can train (typically 3-6) **Recommended:** - **Target race time**: Goal finish time or pace - **Recent race results**: Previous race times to establish current fitness level - **Training background**: Months/years of consistent running - **Injury history**: Any recurring issues or limitations - **Other constraints**: Schedule restrictions, terrain access, weather, life stress **Handling missing information:** - If target time is not provided, ask about recent race performance or typical training paces - If training days are unclear, suggest 4-5 days as a reasonable starting point - If race date creates a very short timeline (< 8 weeks for marathon), flag this concern ### 2. Calculate Training Paces **IMPORTANT**: Use the `calculate_paces.py` script to generate training paces based on the target race time and distance. This ensures consistent and accurate pace calculations. **How to use the pace calculator:** The script is located at `scripts/calculate_paces.py` (relative to this skill's directory). ```bash python3 scripts/calculate_paces.py --distance --time ``` **Examples:** ```bash # 5K in 20:00 (paces per mile by default) python3 scripts/calculate_paces.py -d 5 -t 20:00 # 10K in 45:30 python3 scripts/calculate_paces.py -d 10 -t 45:30 # Half Marathon in 1:35:00 python3 scripts/calculate_paces.py -d 21.0975 -t 1:35:00 # Marathon in 3:30:00 python3 scripts/calculate_paces.py -d 42.195 -t 3:30:00 # For per-km paces instead of per-mile python3 scripts/calculate_paces.py -d 10 -t 45:00 --per-km ``` **Output format:** The script calculates six pace zones based on percentage adjustments from race pace: - **Easy**: 120-130% of race pace (recovery and aerobic development) - **Steady**: 110-115% of race pace (aerobic endurance, used primarily for marathon/HM) - **Threshold**: 103-107% of race pace (comfortably hard, lactate threshold work) - **VO₂max**: 95-98% of race pace (interval training, hard but repeatable) - **Repetition**: 90-93% of race pace (short, fast reps for speed and economy) - **Race**: 100% of race pace (target race effort) **Workflow:** 1. Run `calculate_paces.py` with the user's target race distance and time 2. Copy the pace ranges from the script output into the training plan 3. Include these paces in the "Training Paces" table of the plan 4. Reference `coaches-guide.md` sections 3 and 6 for additional context on intensity definitions and how to apply these paces in workouts **Note**: The script provides pace ranges in minute/mile format by default (use `--per-km` for minute/km format). Pace ranges account for terrain, weather conditions, and day-to-day variation. Always remind athletes that these are guidelines and should be adjusted based on how they feel. ### 3. Design the Phased Structure Read `references/coaches-guide.md` for comprehensive guidance on plan design principles, phase structures, and distance-specific emphases. **Key sections to reference:** - Section 1: Core Principles - Section 2: The "Shape" of a Good Plan (Phases A-E) - Section 4: Weekly Architecture - Section 6: Distance-Specific Emphases **Determine phase durations** based on total plan length and race distance: - **Foundation/Base**: Build aerobic capacity and durability - **Build/Development**: Introduce and expand quality workouts - **Specific/Peak**: Race-specific preparation and intensity - **Taper**: Reduce fatigue while maintaining sharpness - **Transition**: (Brief mention for post-race) **Apply the plan length guidelines** from section 7: - 8 weeks: Short build, assumes existing base - 10-12 weeks: Standard for 5K/10K, workable for HM - 12-16 weeks: Common for HM, minimum for experienced marathoners - 16-20 weeks: Marathon standard **Scale appropriately** using section 8 guidelines: - Adjust volume, workout duration, and recovery based on ability level - Apply the "minimum effective dose" principle for newer athletes - Avoid common design errors from section 9 ### 4. Structure the Weekly Microcycles Build each week using the principles from section 4 of the coaches guide: **Weekly template:** - 1-2 quality sessions (threshold, intervals, or race-pace work) - 1 long run - Remaining days easy (with strides 1-3x/week) - Optional: 1 strength training day **Important workout structure rules:** - ALL interval workouts must be **distance-based** (e.g., "5 x 1 mile", "4 x 800m", "3 x 1km") - Never use time-based intervals (e.g., "5 x 4 min") - Every interval workout follows: **warm-up → intervals → cool-down** structure - Specify distances in miles, meters, or km (e.g., 1.5 miles, 400m, 2km) **Progressive overload:** - Increase volume gradually (typically 5-10% per week) - Follow 3:1 or 2:1 build-to-recovery patterns - Include planned deload weeks (~15-30% volume reduction) **Distance-specific emphases** (from section 6): - **5K**: Focus on VO₂max and speed-endurance - **10K**: Emphasize threshold work with supporting speed - **Half Marathon**: Threshold durability and long run progression - **Marathon**: Volume, marathon pace durability, and fueling practice ### 5. Create Week-by-Week Schedule For each week of the plan, specify: - Week number and phase - Total weekly mileage/volume - Specific workouts for each training day: - Day of week (or Training Day 1, 2, etc.) - Workout type (Easy, Threshold, Intervals, Long Run, etc.) - Workout details (distance-based, pace, structure) - Purpose or focus of the session **CRITICAL: All interval workouts MUST follow this structure:** - **Warm-up** (distance + pace) - **Intervals** (number x distance @ pace, with recovery distance/time) - **Cool-down** (distance + pace) **All intervals must be DISTANCE-BASED, not time-based.** Use miles, meters, or kilometers (e.g., "5 x 1 mile", "4 x 800m", "3 x 1km") rather than time-based intervals (e.g., "5 x 4 min"). **Workout description format examples:** - "Easy 45 min + 6 strides" - "Threshold: 1 mile easy warm-up, 4 x 1 mile @ T pace (0.25 mile jog recovery), 1 mile easy cool-down" - "Long Run: 90 min easy" - "Intervals: 1 mile easy warm-up, 5 x 1 mile @ I pace (0.25 mile jog recovery), 1 mile easy cool-down" - "Marathon Pace: 1 mile easy warm-up, 2 x 2 miles @ MP (0.5 mile jog recovery), 1 mile easy cool-down" - "Long Run with quality: 14 miles, last 3 miles @ steady pace (S)" **Recovery within intervals:** - Use distance-based recovery: "0.25 mile jog", "0.5 mile jog", "400m jog" - Or time-based recovery: "2:00 jog", "90 sec jog" (but prefer distance-based) ### 6. Verify Weekly Mileage Using interval_calculator.py **IMPORTANT**: Before finalizing the weekly mileage totals, use the `interval_calculator.py` script to accurately compute the distance for each interval workout. **Why this is critical:** - Manual calculations of workout distances are prone to error - The script ensures accurate totals including warm-up, intervals, recovery, and cool-down - This prevents understating or overstating weekly mileage (which can lead to overtraining or undertraining) **How to use the calculator:** For each interval workout in your plan, run the calculator with the workout parameters. The script is located at `scripts/interval_calculator.py` (relative to this skill's directory). ```bash python3 scripts/interval_calculator.py \ --warmup \ --intervals --interval-dist --interval-pace \ --recovery \ --cooldown \ --easy-pace ``` **Example:** For "1 mile easy warm-up, 5 x 1 mile @ I pace (0.25 mile jog recovery), 1 mile easy cool-down": ```bash python3 scripts/interval_calculator.py \ --warmup 1mi \ --intervals 5 --interval-dist 1mi --interval-pace 6:15 \ --recovery 0.25mi \ --cooldown 1mi \ --easy-pace 8:00 ``` Output: ``` TOTAL DISTANCE: 8.25 mi TOTAL TIME: 1:01:15 ``` **Workflow:** 1. Design your interval workouts following the standard structure 2. Run `interval_calculator.py` for each interval workout to get exact distance 3. Add up all training day distances (easy runs, intervals, long runs) for the week 4. Verify the weekly total matches your intended volume progression 5. Update the "**Total Volume**: X miles/km" for each week with accurate totals **Note:** For easy runs and long runs without structured intervals, you can estimate distances directly. Only use the calculator for workouts with warm-up, intervals, recovery, and cool-down components. The calculator defaults to miles but can use kilometers with `--unit km`. ### 7.
