Whether you're chasing a marathon PR or your first triathlon, set your goal race and Endurance by Design builds a personalized plan that gets you there, adapting every day to your body and your schedule, so you reach the start line ready and the finish line proud.
Millions of motivated athletes train sub-optimally, plateau, get injured, or quit, and pay for tools they never master.
$150 to $300/month and limited availability put real coaching out of reach for the 95% of age-groupers who train without one.
PDF and template plans can't adapt to a missed long run, a bad night's sleep, or a sudden work trip.
TrainingPeaks and WKO assume you already think like a coach. Most athletes just want: what do I do today?
Running apps stop at the run. Triathlon means juggling swim, bike and run across disconnected tools. Few plans flex to the athlete you actually are.
Endurance by Design turns the race you're chasing into a periodized, science-backed plan, then watches your data and adapts daily so nothing knocks you off course.
From your goal race, date and weekly hours, AI builds a full multi-sport plan on the proven 80/20 method in seconds.
Reads sleep, HRV & training load from Apple Health to score your daily readiness.
Missed a session or feeling flat? The plan realigns without losing structure.
Today's workout on phone & watch, with intervals, zones and pacing built in.
Five disciplines. One adaptive plan. One subscription.
Training for a marathon? Your plan centers on run, strength and recovery. Racing a tri? It brings in swim, bike and brick. Same engine, built around your sport.
Three steps from the goal in your head to the medal around your neck.
Pick your A-race and date, anything from a 5K to a full IRONMAN, then add your B and C races so the season is prioritized around them.
A periodized base, build, peak and taper plan, generated in seconds and laid out day by day across every discipline.
Daily readiness keeps you in the right zone, and the plan adapts the moment life gets in the way, so you start the race ready and finish it proud.
From open-water swims to long rides to trail miles, your plan flexes to your sport and your week.
Everything an athlete needs to train smart: generation, daily readiness, adaptation and execution.
Periodized base / build / peak / taper plans tailored to your race, timeline and weekly hours.
A 5-factor algorithm of sleep, HRV, fatigue, stress and training load guides today's effort.
Every session is reviewed by an AI coach for appropriateness, with insights and feedback.
Rest mode, lighter day, customize week & vacation mode: life-proof without losing structure.
Missed sessions are detected and rescheduled intelligently, protecting your recovery rules.
Interval timing, zone cues, pace targets and haptics, on your phone and Apple Watch.
A/B/C race priorities, auto-injected race-day workouts and goal-time pacing strategy.
Offline-first with automatic background backup and cross-device restore.
It's the distribution elite endurance athletes use, while most amateurs train too hard, too often. Our engine enforces 80% easy, 20% hard automatically, so every plan is built the way the best coaches build them.
Daily readiness: 5 weighted inputs
Outputs a 0 to 100 score that sets today's status and training recommendation (push, normal, easy or rest).
Rather than fight Apple and Strava for your wrist, Endurance plugs into both, and reads your Garmin activities through Strava.
A native companion app pushes today's workouts to your wrist with live, block-by-block timing.
Reads sleep, HRV, resting HR and workouts to power your daily readiness score.
Train on your Garmin watch and your completed activities flow into Endurance through Strava to update your metrics.
Two-way sync: completed sessions post as activities, and incoming activities update your metrics.
"After a decade of racing, I'd tried every way to train: self-coaching, rigid templates, and a $200-a-month coach. The missing piece was always a plan that adapts to you and gets you to the start line ready. So I built it."
Swim, bike, run, brick and strength, plus built-in recovery. Whether you're training for a 5K, a marathon, or a full IRONMAN, one adaptive plan covers every discipline.
A PDF plan can't react when life happens. Endurance reads your sleep, HRV and training load each day, scores your readiness, and realigns the plan when you miss a session or need to back off, without throwing away your periodization.
It pulls health data from Apple Health, mirrors workouts to Apple Watch with live timing, and syncs two-way with Strava, so activities from your Garmin or other watch flow in automatically.
No. The app does the coaching thinking for you and tells you exactly what to do today, why, and how hard. The 80/20 sports-science method is built into every plan automatically.
Pricing, and any free trial or introductory offer, is shown in the app and on the App Store before you subscribe, and it may vary. You can view current pricing and manage or cancel your subscription anytime in your Apple ID settings.
