It starts great. Then Tuesday happened:
The plan doesn’t care. It just sits there, saying “5 miles + 3 strides” like nothing changed.
So you push through. The weird knee turns into six weeks off. You start over.
Every runner has a graveyard:
None of them could bend. None of them could listen. And nobody noticed when you stopped caring.
That's where Carl comes in.
Running doesn't need another dashboard. It needs a coach who knows you.
Connect Strava or Garmin. Talk to Carl on WhatsApp, Telegram, or text (US).
No card needed.

Best for runners who already have a plan and want to see how their body is handling it.

The coach behind Carl
Hey, I’m Jeremy, running coach and ultramarathoner.
I failed at running for decades, and it wasn't for lack of data. I had the watch, the heart rate zones, the pace targets, the recovery scores. I hit my numbers right up until something hurt. The dashboard knew what I did. It had no idea how I felt.
So I started training by feel, and the injuries stopped. 12,000+ miles, 12 ultramarathons, a 100-mile finish, zero injuries. I still wear the watch. It just doesn't run my training anymore.
I do still love the numbers in their place. I keep a free set of pace and race calculators at running-calculators.com for anyone who wants them.
I built Carl to coach the way I coach. When my ankle started acting up, I told Carl. He moved me to the bike, added mobility work, and kept the plan moving. My fitness stayed, and the ankle got better. Zero injuries doesn't mean nothing ever hurt. It means I caught it early.
Built from what you actually did and how it felt. Say yes, or tell him what to change. And when Wednesday goes sideways, the plan moves with you.

The doctrine
The best plan is the one you're healthy enough to follow next month. Carl would rather cut one Tuesday than cost you a month on the couch.
Big engines are built by showing up, not by hero workouts. Carl protects the streak that actually builds you.
Bike rides, gym sessions, long walks: they're training, not footnotes. Strength is what makes you faster and more durable.
Kids, work, travel, a rough night. Training bends but doesn't break, and Carl rebuilds around whatever the week throws at you.
Carl has read the field: exercise physiology, coaching systems, injury and rehab research. Unusual case? The answer comes from evidence, not a hunch.
"I've read more training science than any one coach could hold in their head. I still spend most of my time telling people to slow down." Carl

I love Training Vibes because I can see how I *felt* on my runs and how it has been trending over time. It gives me honest feedback that I sometimes have difficulty giving to myself. Highly recommend.
Rob HFounder of the WKRCTraining Vibes helps me keep an eye on how I'm feeling — take my foot off the gas when I'm at risk of getting injured, and work out what's working well when I'm feeling good. A clean interface that makes you stop and reflect. Super simple to use.
As a hobby jogger still learning how to run properly, Training Vibes gives me a better outlet to think clearly about my runs and how my body is responding. The trend info has been really helpful to remind me when I need to back off or I can pick it up.
Bradley BratcherCEO of Year 50Training Vibes is guided by how your body feels, not just performance metrics. 'Vibes' are easy to understand and take the pressure off chasing numbers. It's a refreshing take on fitness tracking.
Milan RajDigital Health & Tech Leader, Engineering ConsultingTraining Vibes is incredibly easy to use across multiple platforms. Zero issues syncing to Garmin. It's accurately pulled all data after every activity. Definitely recommend!
There's finally a way to track the way I feel during a run and discover how that impacts my training. Whether you rely on this data by itself or as a supplement to heart-rate data, it is a game changer.
Steve ColeAttorneyI've always trained according to how I feel, but never kept a log of how my body is responding. Sometimes I push too hard. Training Vibes makes it super easy to use, and have a record of how my body is responding.
This is fantastic, a great way of tracking runs and able to reference back on previous runs super quick and so easy to use.

A human coach is expensive,
and not always there.
A static plan is generic,
and bends for nothing.
Most training apps are all dashboards,
and don't know when to back off.
Winging it is free,
until your knee sends the bill.
Carl has personality.
And he knows what he's doing.

Talk to Carl. Tell him about your runs, your body, your week. He handles the rest.
Connect Strava or Garmin, or skip. Connect your messaging app, and you're talking to Carl.
An AI coach built by Jeremy Singh, a runner and coach. Jeremy built him to coach the way he coaches: listen first, protect the athlete, play the long game. He talks with you in your texts (Telegram, WhatsApp, or SMS) like a coach would.
The Journal records how every workout felt, so you can spot patterns. Coach Carl coaches you: he plans your week, adjusts it when life happens, and remembers everything you tell him.
Carl coaches you every day. Jeremy reviews your plan every week, is in the chat with you and Carl so you've got two coaches in your corner, and gets on a call with you once a month. Spots are limited so he has time for every runner.
No. Carl writes your weekly plan, but the plan is the least of it. The product is the conversation: the check-in after a rough run, the adjustment when your week explodes, the question about that ankle you mentioned twice. Carl writes your week, then adjusts it every time something changes.
A chatbot waits for you to ask. It doesn't see your runs, doesn't check in after a workout, and won't notice when you go quiet for a week. Carl does all three, and rebuilds your week the moment something changes.
The activities you sync from Strava or Garmin, and what you tell him. That's it. The conversation stays between you and Carl. Your data is used to coach you, never sold.
No. Carl works best connected to Strava or Garmin, but tell him in plain words ("Ran 3 miles today") and he'll track it.
Yes. Just tell Carl, or use the link in your receipt, or go to app.coachcarl.run/settings and change your subscription. Cancel during the trial and you won't be charged. When you cancel, you drop to the free Journal and your history stays.
Carl meets you where you are. He was built to start you too easy rather than too hard, and if something hurts, the plan bends around it. He's not a doctor and won't pretend to be one; he'll tell you when something needs a human professional.
