Your pace this week is 5 sec/km faster than last week. Keep it up!
I'd suggest a 15km long run on the Tokyo Marathon course tomorrow. Weather looks perfect.
Your ACWR is above 1.3. Today, I'd recommend an easy recovery run at 6km.
Amazing run today! You've hit 500km total distance — a huge milestone! 🎉

What is the virtual course experience?
We use actual marathon course data to generate a virtual route near your current location. Experience the same distance and course profile as the real race, right in your neighborhood.
Do I need an Apple Watch?
No, all core features work with iPhone alone. Apple Watch adds real-time pace, heart rate data, and wrist-based navigation.
About the 7-day Pro trial

Does it work offline?
Route generation requires an internet connection, but tracking a previously generated route works offline.
