Train by % FTP
If you have a power meter, the engine prescribes in % FTP (Coggan zones P1–P7). No power meter? Falls back to HR and the plan still works.
Cycling · road & MTB
Your cycling plan, periodized.
Vetta builds the week by power, HR or pace — road or MTB. Sweet-spot, sub-threshold, VO2max, Z2 endurance — every block has its place, ordered by phase.
Sweet-spot or polarized
Pick the philosophy (Coggan, sweet-spot, polarized, MTB XC) or let the engine decide. Each one splits intensity and volume differently.
MTB is its own thing
MTB has its own archetypes (short singletrack intervals, technique, strength-endurance). It's not running on a bike.
ACWR always watched
The engine won't push your load past your safe ramp. Weeks come from your real CTL, not a template.
