Vekta’s Training Structure Builder enables you to generate detailed, structured training sessions - automatically synced to your devices and fully editable.

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).

Here are a few ways you can describe sessions that generate structured outputs:

3-Hour Ride with Anaerobic Efforts: 1h30 aerobic, followed by 6 x 30-second maximum power intervals with 4'30 recovery, 1h aerobic.

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.

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.

3h Lactate Clearance including 2 x (4 x (1min 500w into 4min 300w) - 20 min recovery)

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.

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.

3h Aerobic with Low-Cadence Work: Include 3 x 10min at threshold < 60 rpm.

2h Steady Zone 2 ride: HR capped at 145 bpm.

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.
