SplitSage

SplitSage is a mobile + web AI-assisted pacing and split planning app for runners training for 10K through marathon. You import recent runs from Garmin/Strava, pick a target race (course profile + weather assumptions), and the app generates a realistic pacing plan with split-by-split targets, effort cues, and “if you’re off by X seconds at mile Y” correction rules. During key workouts, it provides audio prompts and post-run analysis focused on pacing errors (starting too fast, drifting on hills, late-race fade) rather than generic stats. It also includes a simple “race week checklist” and fueling reminders tied to your pace plan. The goal is not to replace coaching; it’s to reduce the most common self-inflicted race failure: bad pacing. It’s brutally realistic about goals and flags when your target time doesn’t match your training data.
