Guided first pairing
TerraFlo checks what your trainer exposes — power, speed, and which control paths it accepts — before any resistance control is used.
Equipment
Saris H3 trainers and TerraFlo
The Saris H3 is a beta-priority smart trainer — quiet, direct-drive, and a natural fit for big-screen route riding with TerraFlo.
Where this family stands
The Saris H3 direct-drive trainer is one of the smart-trainer families TerraFlo is prioritizing. Measured power drives your speed through the route's real physics, and grade simulation can follow the filmed road where supported — which pairs especially well with a TV-first setup in the workout room.
As with every trainer, TerraFlo confirms exact behavior during pairing and stays inside what your unit reports.

What happens when you pair
Brand names orient; pairing decides. TerraFlo interrogates the machine in front of it — which telemetry it sends, which controls it accepts, and where its limits are — and adapts the workout to fit.
If your Saris model doesn't respond during pairing, register for beta with the exact model name — real setups drive the compatibility roadmap.
Route-true ride feel
Measured power, real route grade, and momentum shape resistance where supported — climbs feel like the filmed road.
Your data stays yours
Completed sessions are private by default and can export to Strava, Apple Health, Health Connect, or TCX where supported.
