- WHY
- Your half-marathon pace gets built here. The last rep should be the fastest.
Marathon, half, 10K, 5K, Hyrox or triathlon. Teecha writes your plan to race day, rewrites it when life gets in the way, and answers when you have a question at 6am.
iPhone only, to start.

Open the app and see what you're doing today. Paces, loads and recoveries are already worked out. Train, then close the app.
One session at a time, with the reason behind it.
Your age, experience and recent results set the starting paces.
Build, race-specific, taper. Worked back from your race date.
My calf has been sore since yesterday. Should I still do the threshold session?
No. Threshold moves to Friday; today is 30 min easy on the bike. If it still pulls tomorrow morning, tell me.
The coach sits in the bottom bar, one tap away. Tell it what's wrong and it rewrites your week. It answers in a sentence, not a lecture. And it won't let you skip the key session.
The length depends on your race and how long you have. Load builds, holds, then drops so you reach the start line fresh.
The week reshuffles itself. The key session comes first, the rest follows.
It counts towards your streak. Teecha asks how your legs feel and adjusts tomorrow.
Tell the coach and it swaps the session. No forums, no guessing.
