The problem we're solving

A real coach used to cost a real coach.

PDFs are paywalled and static. Other AI coaches charge $15+/month and assume you already train like a pro. Human coaches start at €150. So most amateurs and ambitious age-groupers train off feel, or not at all.

Static PDF plan

Paywalled. Doesn't budge.

Miss one Tuesday and the rest is guesswork.

$50–150 one-off
Other AI coaches

$15+ a month, gated for pros.

Designed for athletes who already know their FTP and zones.

$15–30/mo
Human coach

€150/mo. 48-hour replies.

Worth it, if you can afford one. Most ambitious amateurs can't.

€150+/mo
Triple Peaks

A few dollars a month. For everyone.

Coaching for the amateur, the semi-pro, the ambitious athlete who never had access.

From $4/mo
How it works

Three things a static plan can't.

01
Step 1 · 90 seconds

A plan, ready before your coffee.

Race, date, days you can train, hours you've got. First week lands on your phone before the kettle boils.

Onboarding · 4 questions, no quiz

02
Step 2 · every session

Every workout tells you why.

One plain-English sentence before each session: why this pace, why today, what it's building. You'll start to get it.

Tuesday's workout · 6×800m at 4:25
Structured workout view showing warm-up, intervals, and cool-down with target paces
03
Step 3 · every Sunday night

Next week adapts to last week.

Skipped Tuesday, slept badly Thursday, ran 12K on a hilly trip. The plan you wake up to on Monday already knows.

Made for you

Built for athletes without a coach.

Three people we hear from most. One of them probably sounds like you.

01
First half-marathon, 12 weeks out

You signed up for Berlin in October. Never raced before.

“I downloaded a free PDF plan. By week 3 my knees hurt and I had no idea if I was on track.”
  • Built backwards from race day. Peak at week 9, taper weeks 11–12.
  • Capped at 4 runs a week. The other days are rest, not optional.
  • Long run grows ~10% a week. Never 8K one Sunday and 14K the next.
02
Coming back from plantar fasciitis

Six months off the bike. Sprint tri in May.

“Last time I came back I re-injured in five weeks. I do not want to do that again.”
  • Tell us once: when you stopped, what happened, how it feels now.
  • First three weeks are mostly swim and easy spin. Running starts week 4.
  • Hard sessions only after two clean weeks in a row, no flare-ups.
03
Working parent, 4–6 h a week

Two kids, a full-time job, and a sub-4 marathon in March.

“Some weeks I get six hours. Some weeks I get two. I need a plan that does not pretend otherwise.”
  • Set a max hours-per-week budget. The plan stays inside it.
  • Miss Tuesday's tempo? Wednesday becomes the workout, Saturday stays long.
  • Every session is ranked. You always know which one to protect.
The plan effect

A plan makes all the difference.

Most amateurs train off feel. Every Monday is a fresh decision. With a plan that adapts, every session has a reason. Here's how four common moments play out.

The moment
With a plan
Without a plan
Monday, 06:47
Slept 5 hours. Tomorrow is a tempo run.
Tempo moves to Wednesday. Today: 30 min easy spin. HRV dropped 12%.
–Push through and feel rough all week, or skip and feel guilty.
Six weeks out
42 days to Berlin. Am I on pace for sub-1:55?
Yes. Long-run pace is 5:35/km for three weeks. Threshold up 4%.
–Last Sunday's long run felt OK. Beyond that, no idea.
Missed Tuesday
Skipped 5×1K intervals. Project went sideways.
Intervals move to Thursday. Friday drops to 40 min easy. Saturday long stays.
–Cram intervals onto Wednesday's hills. Saturday wrecks you.
Race week
Berlin is Sunday. How much do I taper?
Volume −40%, intensity −20%. Two 4×400 openers Thursday at race pace.
–Read six Reddit threads. Skip Friday. Sleep badly Saturday.
