Talk with your data.
Train smarter. Smash your goals.
Most apps track your training. Lactate Training understands it. Ask questions about your sessions. Get answers rooted in your physiology, your history, and your goals. Not generic advice. Real coaching intelligence.
Talk with your data. Understand every session.
Most apps tell you what happened. Lactate Training tells you what it means.
Every session you do contains more information than a chart can show. LT reads it — lap by lap, effort by effort — and turns it into plain English coaching insight that's actually yours.
Sync your session
Finish your run. LT pulls it straight from Garmin or Strava — no manual upload required.
LT reads the data
Heart rate, pace, cadence, elevation, lap splits — all analysed in context of your recent training history.
You get real answers
Not a summary. A coaching conversation. Ask follow-up questions. Dig into the detail. Understand what actually happened.
Your sessions, finally explained.
Upload a workout and LT breaks it down — lap by lap, effort by effort, in plain English. Not just numbers on a screen. Real insight. Why that tempo felt hard. Whether your pacing was right. What your body was actually doing. It's the difference between collecting data and understanding it.
The coaching layer other apps don't have.
LT doesn't just summarise your session — it reasons about it. It knows your recent training load, your injury history, your target race. So when it analyses your long run, it's not giving you a generic readout. It's giving you context that's actually yours.
Every analysis looks forward, not just back.
Every analysis is forward-looking. LT doesn't just explain the past — it uses it to shape what comes next. Fatigue trends. Recovery signals. Readiness for your next hard effort. That's not a workout summary. That's a coaching conversation.
- Lap-by-lap breakdown in plain English
- Context-aware analysis based on training history
- Injury and load reasoning built in
- Forward-looking recommendations after every session
- Ask follow-up questions directly in the app
- Works with Garmin and Strava data automatically
How you feel matters. LT listens.
Training isn't just what you do. It's how you're doing.
The best coaches don't just look at your workout data. They ask how you're feeling. LT does the same — every day, in a way that actually feeds into how it coaches you.
Open LT each morning
Takes 60 seconds. LT asks how your body feels, how your head is, what's going on in life. Free text — no forms, no sliders.
LT builds your picture
Your responses feed directly into how LT interprets your training and what it recommends next.
Patterns emerge over time
After a few weeks, you start seeing what actually affects your performance. Not theory — your data, your patterns.
More than a mood tracker.
Every day, LT checks in. Not with a generic form. With a real conversation. How's your body feeling? How's your head? What's going on in life? That information feeds directly into how LT coaches you. Because a hard session on a bad day isn't the same as a hard session on your best day.
The context other apps miss.
Stress. Sleep. Work. Family. Travel. Life doesn't stop when training starts. LT understands that. Your daily check-in gives it the full picture — so the analysis and planning it gives back is built around your real life, not an idealised version of it.
Build the habit. See the pattern.
Over time, your check-ins become one of the most powerful data sets LT has. Patterns emerge. You start to see what actually affects your performance. What drains you. What fires you up. That's self-knowledge that makes you a better athlete.
- Daily conversational check-in — no forms or sliders
- Physical and mental wellbeing tracked together
- Life load context fed into coaching AI
- Patterns surfaced over time
- Integrates directly with session analysis and planning
- Takes less than 60 seconds
A training plan that actually fits your life.
Not a rigid schedule. A living, breathing training brain.
Most training plans collapse the moment real life happens. LT's calendar is built around the fact that life always happens — and adapts accordingly.
Build or import your plan
Start from scratch with LT's guidance, or import an existing plan. Screenshot, text, whatever you have.
Add your life context
Work trips, social commitments, busy periods — LT factors all of it into how it builds and adjusts your schedule.
LT adapts in real time
Missed a session? Feeling rough? Something came up? LT adjusts the plan forward without losing sight of the goal.
Plans that adapt — not collapse.
Most training plans break the moment life gets in the way. A missed session, a work trip, a bad night's sleep — and suddenly you're behind. LT's calendar is different. It understands that life happens. When things shift, it adapts. The plan moves with you.
Your calendar knows more than your schedule.
Work commitments. Travel. Recovery days. Social plans. LT factors all of it in. So when it suggests your long run, it's not just looking at what day of the week it is. It's looking at everything happening around it. That's real-life adaptive planning.
Past, present, future — connected.
The calendar isn't just a place to store workouts. It's the bridge between what you've done, where you are now, and what needs to happen next. Every session placed is placed for a reason. LT can tell you exactly what that reason is.
- Adaptive planning that adjusts when life gets in the way
- Life load integration — work, travel, fatigue, social
- Conversational plan editing — just tell LT what's changed
- Session placement with AI reasoning explained
- Import any existing plan — screenshot, text, or voice
- Connected to session analysis and daily check-in data

Ask anything. Get a real answer.
Not a chatbot. A training partner that knows your history.
There are questions every athlete has that no app has ever been able to answer properly. Am I overdoing it? Should I race this weekend? Why does my easy pace feel so hard? LT can answer all of them — because it knows you.
Ask your question
Text or voice. Any time. Whatever's on your mind about your training, your race, your recovery.
LT answers in context
Not a generic response. An answer based on your actual training data, history, and goals.
Keep the conversation going
Ask follow-ups. Dig deeper. LT remembers what you've talked about — so conversations build over time.
The conversation that changes everything.
Most fitness apps are one-way. You give them data. They give you charts. LT is different. You can ask it anything — and it answers based on your training, your physiology, your goals. Why is my resting HR elevated? Am I ready to race? Should I do this session today? Real questions. Real answers.
It remembers. It connects the dots.
LT's AI doesn't start from scratch every time you open it. It knows you. It remembers what you've talked about, what sessions you've done, what's been going well, what hasn't. So conversations build on each other — just like they would with a real coach who's been with you for months.
Your coach. On demand.
3am before a race. Post-run on a Tuesday. Waiting for the train. Whenever you need to talk through your training, LT is there. Ask via text or voice. Get a response that's rooted in your actual data, not generic advice copied from a training blog.
- Context-aware answers based on your full training history
- Text and voice input — no friction
- Longitudinal memory — conversations build over time
- Ask about specific sessions, upcoming races, or general training
- Injury nuance — LT understands load, not just effort
- Available 24/7 — no waiting for a coach to reply
What Athletes Say
Real athletes. Real results.
"LT told me things about my training I've been trying to figure out for two years. My coach charges £100/month and doesn't give me this level of insight."
"I never understood why some sessions felt terrible despite good HRV scores. The check-in helped me see the pattern — it was always work stress. Game changer."
"I travel every other week for work. Every other training app just falls apart. LT is the first one that handles it without me having to manually fix everything."
"I asked LT if I should run a half marathon six weeks after a calf strain. It didn't just say yes or no — it walked me through my load, my recovery pattern, and what signs to watch for."
