For marathon runners
Not a summary. Not a scoreboard. A read on what actually happened, in the voice of a coach who's been paying attention.
Debrief · Thursday
Quicker than an easy run usually lives for you. 4:58/km, about 15s/km faster than your usual easy. HR stayed low, so nothing physical. But the plan wanted easy to be easy.
You mentioned the calf on Tuesday. Easy runs are where you bank that signal, and 4:58 is harder to justify if the calf’s still talking. Not my call, but worth sitting with before tomorrow.
A plan is a prescription. It can't read what came before, what came after, or the day you actually had.
A plan tells you Tuesday is a tempo. It can’t know the calf has been niggling since the long run, that you’ve got a work trip Thursday, that the kids haven’t been sleeping, or that race day is the reason any of this matters. Coach Casey holds the rest of the picture, and brings it to every read.
Plan wants 8×3min tempo. But you mentioned the calf on Tuesday, and you’ve got the work trip this week. Not a great week to push through something that’s already talking.
I’d swap for an easy 45 and save tempo for Saturday. Your call.
Most of what makes a coach good isn't in your Strava data. It compounds.
The first month is useful. The third is sharp. By month twelve, Coach Casey knows things about your running that you’d struggle to write down.
Reads your runs. Catches the obvious.
Knows your easyisn’t the book’s easy. Remembers the calf from February. Knows the kids have been sick.
Knows which races matter. Knows the kid, the sleep, the work patterns, the way you fall apart in February. The patterns you didn’t know you had.
Months later, in the middle of a different conversation, the right detail comes back.
“Pulled up sore on the left calf around the 8k mark. Backed off.”
“Calf chatter on the descent at 19k. Same side as April. Worth keeping an eye on, not worth panicking about.”
Coach Casey sits alongside the plan you've already got, written by you, by a coach, by an app, by anyone.
Five minutes of setup, then keep running the way you already were.
Upload the plan, paste it, describe it. Whatever you’ve got. Five minutes. Once.
No new app during the workout. No daily check-in. Coach Casey reads each run as it comes in, against the plan and everything that came before.
A debrief after every run. A review at the end of every week. Chat, whenever you want to dig in.
Annual is what we recommend. Monthly is there if you want to try it that way.
A$199 a year. Roughly A$16.60 a month.
Annual is priced to keep you through the window where Coach Casey gets sharpest. The first three months are useful. Month six is when the memory really earns its keep. Monthly is a fine way to try it past the trial; switch to annual any time.
Cancel monthly any time. Annual is a year commitment, but if you cancel before it’s up, unused months refund pro-rata, automatically. No claw-backs, no retention emails.
The questions that come up before a trial. Answered honestly.
No. Coach Casey reads what you're already doing. Your plan, your runs, what's been going on around them. Then writes back like a coach paying attention. The plan stays yours, or your coach's, or your group's.
Strava is the only feed Coach Casey reads. If your run shows up there, it gets debriefed. No second app on the run, no morning check-in.
Update what you tell Coach Casey, the same way you'd tell a coach. The next debrief reads against the new plan. Memory of the old block stays. Pacing, fatigue patterns, what worked.
It accumulates the context that Strava data alone can't capture: which races mattered, which weeks bent, what your easy actually looks like in July. Three months in, you'll feel the difference. By month six, the recall starts surprising you.
Strava data comes in through their API. The only thing written back is the verdict line, one sentence under each debriefed run's description, which you can turn off in settings with one tap. Your runs, plan, and chat history are stored on Supabase, in Tokyo. Coach Casey uses large language models to write debriefs and respond to you; your data is never used to train them.
14 days, no card required, everything enabled. Cancel monthly any time. Annual is a year commitment, but if you cancel before it's up, unused months refund pro-rata, automatically. No claw-backs, no retention emails.

Coach Casey started as a private tool I built to debrief my own runs while training for the Melbourne Marathon. I’m a coach. I’m also a coached athlete. I wanted the read on each run that my own coach gives me, specific and in context, between sessions, on every run.
It’s a one-person product so far. I read every support email myself. I use Coach Casey on every run I do, including the ones I’d rather forget.
14 days free. No card required. If it isn’t sharper than what you’ve got, leave. We won’t make it weird.
