Everything irontri does

Built for
triathletes.
Not everyone.

Every feature was built because triathlon is three sports, one race. Generic training apps don't get that. irontri does.

Your training plan

Not a template.
Your plan.

🏁
Sprint, Olympic, T100, 70.3 or Full Ironman — each distance has its own structure and approach
📅
Tell us how many hours you can train per week and which days — your plan works around your life, not the other way

Week 3 of 36 · Build Phase 8h 25m total
🚴 Bike
28 km/h · Zone 2
Endurance Engine
3h long ride · 85-90rpm · Keep HR in Zone 2 the entire ride. No surging.
"Week 3 long ride is about time on the bike, not speed. Your aerobic engine is being built right now — every minute at Zone 2 matters more than you think."
02
Session detail

Every session has
a purpose.

Not just "easy run" or "bike intervals". Every session comes with exact pace targets, heart rate zones, a full warm-up, main set with rest periods, cool-down, and a coach note that tells you why you're doing this specific session this specific week.

🏊
Swim: interval distances in metres or yards, rest periods, and technique cues based on your weakness
🚴
Bike: cadence targets, speed or power zones, and whether it's indoor or outdoor — every detail specified
🏃
Run: pace per km or mile, cadence, stride cues — and brick runs that build race-ready legs
🏊
Threshold Intervals
Thursday · 70 min · Zone 4
1:45/100m
🔥 Warm up
400m easy freestyle · focus on long strokes and breathing rhythm
💪 Main set
8×100m @ RPE 8 · 15 sec rest
Focus on hip rotation and early catch
💬 Coach note
"8×100s at threshold this week because we're entering Build phase. Your aerobic base is ready — now we sharpen it."
03
Adaptive training

Your plan learns
as you train.

Rate each session after you finish. Too easy? Your upcoming sessions of that sport get harder. Struggling? They back off. irontri rewrites your future sessions automatically — so your plan stays calibrated to your actual fitness, not a guess from week one.

📊
Rate 1–5 after each session. Takes 2 seconds. Makes every future session more accurate
🧠
Adapts by sport — a hard run doesn't change your swim sessions. Each discipline is calibrated separately
📈
Your plan gets smarter the longer you use it — the feedback loop compounds over weeks

Strava integration

Train. Finish.
Already done.

Connect Strava once. Every ride, run, and swim you record automatically ticks off the matching session in your plan. No manual logging. No copy-pasting. You just train — irontri handles the rest.

🔄
Works with Garmin, Apple Watch, Wahoo, COROS, and any device that syncs to Strava
📍
Activities are matched by sport type and date — a 46km ride on Saturday ticks the Saturday ride session
🔒
We only read activity type, date, and distance. We never write to Strava without your explicit action

Race day ready

Taper lands on
the right week.
Every time.

Your plan counts backwards from race day. Base, build, peak, taper — each phase lands exactly where it should. You'll arrive at the start line fresh and sharp, not grinding out a hard session three days before your race.

📆
Set your race date once — the entire plan periodises around it automatically from day one
🏁
Race week is always 30–45 min easy sessions only. No surprises, no hard efforts close to race day
⏱️
Enter your goal finish time — irontri breaks it into swim pace, bike speed, and run pace, then builds every session around those targets

Your units

km or miles.
Your choice.

irontri works in whatever units you train in. Switch between metric and imperial at the start of your quiz — every pace target, bike speed, swim distance, and coaching note in your plan will use your preferred units throughout.

🌍
Metric: km/h, min/km, metres per 100m — for the majority of the world
🇺🇸
Imperial: mph, min/mile, yards per 100yd — fully consistent throughout your plan, no km leaking in
⚡
Set it once at the start — every session, every week, every target is in your units automatically

"I've used Garmin Coach and generic PDF plans before. This is the first time sessions have actually explained why I'm doing them. The coach notes make a huge difference."

"Finished my ride on Saturday, went to check it off — it was already done. Strava had synced it automatically. That alone is worth it for someone who hates admin."

"I told it my swim was my weakness. Every single swim session had specific technique cues — catch drills, hip rotation reminders. It actually listened."
