AI voice coach for runners
Your coach.
In your ear.
It knows your pace. It knows your heart rate. It knows you. And you can talk to it.
A private AI running coach that runs with you — and talks with you while you're out there.
During your run
A coach who knows how hard you're working.
Phone in your pocket, eyes on the path. Ask how you're doing and talk it through — your coach answers with your effort right now in mind.
You“Can I hold this pace for another three kilometres?”
Coach“Your heart rate keeps creeping up at the same pace. Ease off a touch and you'll finish strong.”
You“How much is a touch?”
Coach“Ten seconds per kilometre. You'll barely feel it — your pulse will.”

Interval training
Make every interval count.
On the track or your usual loop, your coach follows every rep and helps you decide when to push on and when to stop — without a glance at your watch.
You“One more rep?”
Coach“Go for it. Your pace held steady across all four, and your heart rate came back down in every recovery.”
You“Same target?”
Coach“Same target. If you drop off it in the last 200 metres, call it there — still a good session.”
Before your run
Plan your run. Just by talking.
Talk through how you're feeling and what you want from today. Plan your intervals or choose today's run — without endless menus.
You“Legs feel good today. What's the plan?”
Coach“Then let's do intervals. Your long run isn't until Saturday, so you've got time to recover.”
You“How many?”
Coach“Five times a kilometre. Start the first one easy — the last two are where it counts.”
After your run
The run ends. The conversation doesn't.
Talk through the run, understand the hard moments and decide what to work on next.
You“The last two kilometres felt terrible. What happened?”
Coach“Nothing went wrong. That was a hard session on top of yesterday's — heavy legs at the end are exactly what we'd expect.”
You“So no need to worry?”
Coach“None. Easy jog tomorrow and you'll be fresh for the weekend.”
Behind the conversation
Built on training science. Made for conversation.
Your coach doesn't guess. It works with the measures coaches and sports scientists rely on: your pace from GPS, heart-rate zones based on your own values, cardiac drift, training load and an estimated VO₂max. The AI's job is to explain what those numbers mean for you — right now, in plain words.
Your zones, not generic ones
Pace zones are built on your own threshold pace, heart-rate zones on your own heart-rate values — not on an age formula.
Cardiac drift
Your pulse is read against your pace. A heart rate that climbs at a steady pace tells a different story than a hard effort.
Load and fitness over time
Training load, fitness (CTL) and an estimated VO₂max from your training history show whether you're building up or need an easier week.
The interpretation and the advice come from AI and can be wrong. How you feel always comes first.
What it does
Everything it does for you. Before, during and after.
01 · Before
Before the ride
- Plans today in a two-minute chat: how much time you have, how fresh you are, what's coming up.
- Turns any workout into blocks, from a photo, a name or your own words.
- Tells you what today will cost tomorrow, before you start.
- Brings in your training history from intervals.icu.
02 · During
During the ride
- Calls every interval change with your target watts or pace, and counts the reps down.
- Spots your bests as they fall, and tells you early when one is in reach.
- Watches your reserve: warns before you blow up, tells you when it's full again.
- Keeps count of your goal: stimulus done, minutes missing, when to back off to stay fresh for race day.
- Answers anything hands-free: hold your headset button and talk. Music keeps playing.
- Stays quiet when nothing matters. You choose how chatty it is.
On your roads
It knows where you ride
- Knows your climbs from your own rides: how long, how steep, your best up there.
- Knows where the road is free: stretches you ride without stopping, hills included, announced before they start.
- Live on a segment: seconds ahead of or behind your best, then your time, your place, and how fresh you were when you set it.
- Rides with your ghost on roads you know: faster or slower than usual, and whether the same speed costs fewer watts than it used to.
- Knows your usual loops: how far and how long to home at today's pace, the last free stretch, and asks when it isn't sure which one you ride.
- Compares with your own rides: the same road wherever you started, similar length, last session.
03 · After
After the ride
- A short debrief: what worked, what to change next time.
- When you'll be fresh again for hard work.
