Your first 70.3 deserves a real coach. Stryde gives you one for $9.99/month. Stryde is an AI endurance coach built for athletes training for a real race - your first marathon, your first half-Ironman, your first ultra. The same coaching principles a human coach would use, adapted to your paces, your weekly hours, and how your body is actually responding this week. WHO IT IS FOR - First-time 70.3 and Ironman athletes - Marathoners and ultra runners chasing a goal time - Triathletes balancing three sports without a human coach - Athletes whose Garmin and Strava can track them but will not coach them WHAT YOU GET - Multi-week training plan adapted to your specific race - An AI coach that knows your paces, race date, recent workouts, and how you are feeling - Structured workouts with pace zones and tips, not "easy run 45 min" - GPS tracking with auto-marked mile and km splits - Strava integration (optional sync both ways) - Race day mental prep, nutrition planning, transition prep - Daily check-ins that actually adapt next week's plan based on your sleep, energy, soreness, RPE HOW IT IS DIFFERENT Most apps track you. Stryde coaches you. Your plan adapts every week based on what actually happened - missed workouts, low energy days, races that went better or worse than expected. Tell the coach your knee hurts and it will modify tomorrow without canceling your race goal. If you have used TrainingPeaks or Final Surge: this is similar, with an AI coach instead of static plans, at half the price, built for athletes who do not have $300/month for a human coach. PRICING Week 1 free - full access to your plan, no credit card required. Then $9.99/month, cancel anytime. No hidden fees. PRIVACY AND SAFETY Stryde is built with conservative coaching principles. The AI knows when to back off, when to push, and when to redirect you to a doctor for chest pain or symptoms beyond normal training fatigue. Built by an athlete, for athletes.
