Run further.
Not harder.
Kallpa reads your Strava data and builds a plan that adjusts every week. Based on what you actually did — not what a questionnaire guessed about you.
Templates don't see your real week.
A PDF plan doesn't know about your Wednesday ride. It doesn't know you slept badly, or that you pushed hard on Saturday. It expects you to adapt to it. Kallpa reads what you actually did. Every week. And adjusts.
Your plan starts from what you actually did.
Kallpa analyses your last 12 weeks on Strava: volume, paces, elevation, frequency, fatigue signals. No questionnaire — your data already knows.
The plan evolves. You don't chase it.
Every week, your VDOT and TRIMP load are recalculated. Heavy week, the plan backs off. You're progressing, it moves with you.
A coherent block toward your race.
Pfitzinger periodisation over 12 to 24 weeks. Not a random pile of sessions, a block that's going somewhere.
We monitor overload signals. Before something breaks.
Kallpa tracks your ACWR ratio and HRV signals. When a week starts running hot, you know before it catches up with you.
Not just running.
You do other things besides run. Cycling, swimming, lifting — classic running apps ignore all of it when calculating your load.
Kallpa pulls every Strava activity into your TRIMP score. Three hard rides in a week can push you past the overload threshold as easily as a heavy running week. Most plans would never know.
Why I built this.
Madrid. April 2024. First marathon. Campus Coach calculated 2:48 from my 1:24 half in Barcelona two months earlier. I believed it.
What the plan couldn't see: gym, boxing five days a week, broken sleep, work stress. My HRV had been in the red for weeks. Nothing flagged it.
Two weeks out: both Achilles tendons, both calves. The physio said don't go. I went. 3:03:33.
Crossing the line: nothing. Months of not wanting to run. Kallpa would have seen all of it. I built it.
