4 runners in 10 get injured while training for a marathon, and some never make the start line. Synka has one goal: get you to the start line, then across the finish line. IT'S NOT THE MILES, IT'S THE SPIKES Most training mistakes are sudden jumps: a long run much longer than anything you did this month, a hard session the day after a hard session, a comeback that starts too fast. Synka builds your plan to race day and smooths those jumps out, week after week. A PLAN THAT FOLLOWS YOU Ten seconds each morning: energy, pain, period. If you are tired, today's session gets easier. After a bad night, the hard session moves to a better day. Short on time? Say how many minutes you have and Synka builds a session that fits. Missed a week? It eases you back in. YOUR CYCLE, TAKEN SERIOUSLY Synka learns which phases of your cycle cost you more and places hard sessions on your best days. On hormonal contraception or without cycle tracking, the plan works exactly the same. EVERYTHING A PREP NEEDS Build, race-specific and taper blocks. Intervals, threshold, tempo, long runs and lighter weeks. One to seven runs a week, a run-walk start for beginners, and guided strength sessions built into the plan. GPS runs with voice-guided pace, your run on the lock screen, sessions sent to your Apple Watch. SEE YOURSELF PROGRESS Your paces are set on your real level, not on a wish. Synka reads your runs from Apple Health and shows the race time you can aim for, your VO2max pace, your freshness, and your pace at the same heart rate: how many seconds you gained in three months. No watch? Everything works by feel. HONEST Every change to your plan comes with its reason. No made-up numbers, no ads, no tracking, no in-app purchase. Delete your account and all your data from the app, immediately. Synka is not a medical device and does not replace medical advice.
