Cursa

You don't start over. From the moment you grant Apple Health permission, Cursa reads every run you have ever logged, from any app, so your PRs are detected before you take your first step and your fitness level is already known. You arrive as yourself, not as a blank slate.

TRAINING PLANS THAT SHOW THEIR WORK Pick any race from the RunSignUp catalog and Cursa builds a plan backward from your finish line. When your week goes sideways and the plan needs to shift, a card surfaces the exact sessions that changed and the plain-English reason beside them. Miss two tempo runs and volume pulls back before the deficit compounds. String together five strong weeks and the plan moves up to match. Nothing is reshuffled without you agreeing to it first. No spreadsheets, no PDFs or paper plans, no decision fatigue, no guessing what to run on Tuesday.

COACHING THAT KNOWS THE WORKOUT After every run, Cursa generates a coaching note using Apple Intelligence -- on-device, not sent to a remote server. Because Cursa built your plan, it knows what today's workout was meant to deliver: the goal pace, the training phase, the intent. The note tells you exactly where you held form, where you drifted, and what that means for the rest of the week. Not a template. Not a run like yours. This run.

INTERVAL WORKOUTS BUILT ON YOUR PHONE, RUN ON YOUR WATCH Drag work and recovery blocks, set target paces, define repeat counts. Send to watch. From that point, your Apple Watch owns the session -- showing current interval, live pace, heart rate, and rep count, with a gentle haptic or voice coaching when you drift off target. You don't need to touch your phone again.

YOUR FULL RECORD, IN ONE PLACE All-time and year-to-date personal records across 1 mile, 5K, 10K, half marathon, and marathon. PRs are detected from real run segments, so a half marathon can surface a 10K PR you didn't know you set. Official chip times from RunSignUp sync automatically when available, and every race result links back to the source run you tracked. Every PR links back to the run where you achieved it.

RACE DAY, HANDLED Before you start, enter the list of people you want to receive a live tracking link. Your friends and family open it in any browser, no account, no download. A moving dot, an estimated finish time that updates as you run. Cross the line and Cursa pulls your official chip time from RunSignUp automatically. No results site. No manual entry.
