Training Structure Builder
Overview
Vekta’s Training Structure Builder enables you to generate detailed, structured training sessions - automatically synced to your devices and fully editable.
Concept
Vekta uses Generative AI to interpret your session's Title, Description, and Training Zones to create a structured session.
Each structure is made up of defined steps. For each step, you can customize:
Step Duration: Define steps by time (e.g. 5 minutes), distance (e.g. 2 km), or leave it open-ended.
Intensity Target: Specify target intensity using:
Watts – Fixed power (e.g. 280W)
% CP – Percentage of your Critical Power (e.g. 90% CP)
Zones – Select from Vekta’s zones or your own custom training zones
Cadence Target (optional): Add a cadence target if cadence is a focus of the session (e.g. 95 rpm).
Heart Rate Target (optional): Set HR targets as a secondary control (e.g. HR capped at 145 bpm).
Examples
Here are a few ways you can describe sessions that generate structured outputs:
Using Vekta's zones
3-Hour Ride with Anaerobic Efforts: 1h30 aerobic, followed by 6 x 30-second maximum power intervals with 4'30 recovery, 1h aerobic.
Using custom zones
Before using custom zones in a session description, make sure they’re defined in the athlete’s Profile > Training Zones. The AI can only reference zones that already exist.
4h Sweet Spot: Warm up, then ride 3 x 20 minutes at sweet spot with 10min of easy pedaling between efforts, cool down.
Intensity from % CP
1h30 Over-Under Intervals: 15-minute warm-up, then 6 x 5-minute over-under intervals (2 minutes at 105% CP, 3 minutes at 90% CP) with 5-minute recoveries; 15-minute cool-down.
Intensity from Power values
3h Lactate Clearance including 2 x (4 x (1min 500w into 4min 300w) - 20 min recovery)
Nested Structure (Max Depth of 2)
1h HIIT Session: 20-minute warm-up, followed by 2 x (5 x 1-minute VO2max intervals with 1-minute recovery) and 5-minute recovery between sets, ending with a 10-minute cool-down.
Critical Power Test
CP Test: Start with a 20-minute warm-up, then perform a 15" max sprint, followed by a 20-minute recovery. Next, do 5 min max, 30 minutes of easy pedaling, and a 20' max effort. Finish with a 20-minute cool down.
Including Cadence Target
3h Aerobic with Low-Cadence Work: Include 3 x 10min at threshold < 60 rpm.
Including HR Target
2h Steady Zone 2 ride: HR capped at 145 bpm.
Current Limitations
The Training Structure Builder is evolving rapidly, but there are a few current limitations to keep in mind:
Cycling-specific only: Structure generation currently applies only to cycling sessions.
No HR-only sessions: While you can add heart rate as a secondary target, sessions cannot yet be generated based on heart rate alone.
