Most training apps give you a plan and walk away. Build Your Legend is different. Powered by StrideIQ™ — our adaptive AI engine — your plan rebuilds every week from your real data. Not adjusted. Rebuilt. The plan you start with isn't the plan you end with. That's the point. HOW IT WORKS 1. Connect Strava — one tap. We scan 6+ weeks of your history to understand your real fitness, not what you wish it was. 2. Set your goal — pick a race, a distance, and a date. StrideIQ™ builds your plan backward from race day. 3. Regenerate each week — when you're ready, hit Generate. Add context (feeling strong, a tough week, travel obligation, a sore knee) and StrideIQ™ rebuilds from your last 7 days. WHAT STRIDEIQ™ DOES FOR YOU → Adaptive weekly plans — every session tells you what to run, how far, and how fast. Intervals, tempo, easy runs, long runs. You always know what to do and why. → Strava-native — zero manual logging. We read your pace, HR, cadence, drift, and fatigue directly from Strava. No self-reported effort. No RPE guesswork. → Auto-deload detection — when fatigue accumulates, StrideIQ™ inserts a recovery week before you ask. No injury. No spiral. → Fitness-matched pacing — no generic pace zones. Your targets recalibrate automatically every week as you get fitter. → Race countdown logic — build, peak, taper, race. All automatic, all timed to your exact goal date. → Context-aware — tell it what's going on before each rebuild. Heavy week at work, a sick day, legs that felt dead. It factors that in, every single time. → Cross-training support — add weight training, cycling, or swimming. StrideIQ™ accounts for your full training load, not just miles. WORKS WITH YOUR GEAR Strava, Garmin, Apple Watch, COROS, Polar, Wahoo, Suunto — if it syncs to Strava, we read it. WHY RUNNERS SWITCH - "I tried another popular running app for 3 months. Plan never matched what my body was actually doing. Within 2 weeks StrideIQ™ had me on a different schedule than I would have built myself — and I PR'd." — Marcus L., Marathon 2:54 - "The auto-deload is wild. I would have run through that fatigue week and gotten injured. It just inserted a recovery block. Like having a coach who actually pays attention." — Priya S., Half Marathon 1:32 - "No setup. No spreadsheet. No effort ratings. It reads my Strava and figures it out. That alone is worth it." — Devon K., 10K 38:42 30 DAYS FREE, FULL ACCESS 30 days. Full access. No credit card. No commitment. If Build Your Legend doesn't change how you train in 30 days, walk away — you won't have paid a cent. A static plan is a prediction. An adaptive plan is the truth. SUBSCRIPTION Build Your Legend is free for 30 days. To continue after your trial, subscribe with an auto-renewing plan: Legend Monthly or Legend Annual.
