Getting back into it

You ran regularly a few years ago. Life got busy. Starting over feels daunting — like you've lost everything you built. Arc builds from where you are now, not where you were. Missed sessions are reframed, never guilt-tripped.

🚴

Active across sports

You run some weeks, bike on weekends, and hike when the trails are good. No single sport defines you — and no app has really understood that. Arc treats every activity as training load. Your Saturday hike shapes Monday's run.

🏅

Still competing, smarter

You race regularly and know your body. But recovery at 55 isn't what it was at 35 — and most apps give everyone the same plan. Arc builds age-aware recovery in automatically. Not as a concession. As strategy.

🎯

Training seriously, time-limited

You have a half marathon in 10 weeks and a full schedule. Every session needs to earn its place. Arc generates periodized suggestions toward your race goal and shows you exactly why each session is there.

Your first training week, in 5 minutes.

Connect Strava, answer a few questions, and Arc builds your week around who you actually are.
