This commit transforms the single GAP calculator into a dual-mode application with two calculators: 1. Original GAP Calculator (preserved): - Maintains all existing GAP calculation functionality - Uses Minetti polynomial and Black GAM data for energy expenditure calculations 2. New GPX Race Pacing Calculator: - Parses GPX files to extract route elevation profiles - Implements iterative solver to find correct base pace that achieves goal time - Generates lap splits (400m, 1k, 1 mile, 5k) accounting for elevation changes - Uses GAP calculations to adjust pace for grade variations - Provides CSV export for splits Key implementation details: - GPXParser: Calculates distances, grades, and smoothed elevation profiles - GoalPaceSolver: Iteratively solves for base pace using reverse GAP calculations - LapCalculator: Generates splits with GAP-adjusted times for each segment - UI: Toggle between calculators, file upload, goal time input, results display The solver ensures that the calculated lap times, when accounting for all elevation changes along the route, will sum to exactly the target goal time. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Add safety-based speed capping for steep downhills (>8% decline) where theoretical GAP speeds are unrealistic and dangerous to achieve in practice. Changes: - Add progressive speed limitation from -8% to -25% grade with max 60% reduction - Cap maximum downhill speed to 1.5x base pace for safety - Track segments where speed capping is applied for transparency - Display visual indicators (⚠️ ) on affected lap splits - Highlight speed-capped laps with yellow background - Show warning message in pacing strategy when adjustments are applied - Add tooltips explaining the safety limitations to users Based on research showing runners cannot achieve metabolically equivalent speeds on steep downhills due to biomechanical constraints and safety concerns. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
