[*]No Garmin 520 dá para controlar a intensidade e a potência. Dá para seguir workouts criados no garmin connect e treinos previamente realizados com o Garmin 520.
[*]O Golden Cheetah recebe a info de Power, Speed e RPM mas não controla o rolo.

Bem me parecia que o golden cheetah controla o rolo:

Many know Golden Cheetah as the super-advanced cycling analytics app that also happens to be open source (and thus free). However, the app has grown to include trainer integration via a trainer mode. Within this mode it’ll allow you to create structured workouts using everything from %FTP to exact wattages or even gradients. Additionally, you can download workouts from the massive online ErgDB data (though, that sometimes can be a bit like sifting through the beach sand for a jelly bean).
The app can also control FE-C trainers, or other trainers via older private-ANT variants. Further, it supports the CompuTrainer. But more than that it can utilize known trainer power curves to estimate power for a number of popular trainers – like the Kurt Kinetic Road Machine and others. This means you’ll just need a speed sensor to in turn get power information. More than that though – the app just supports so many different data types and sensors. Aspects like BSX and Moxy sensor support, the ANT+ remote control for controlling the trainer page, and even the FIT2.0 developer fields that both Training Peaks and Strava have basically shunned.
The app can consume ANT+ sensor data using a USB stick and then display/record that within the trainer view. Afterwards, your data can easily be uploaded to numerous sites either via the direct file option, or the integration with sites like Strava and Training Peaks. Overall the app is definitely worth a look, especially if you’re on a budget and just need the core recording functionality.
(Note that while the current production version is 3.3 and technically ‘prior’ to my cut-off date, their upcoming 3.4 version is in Release Candidate status, and brings many additional trainer features as outlined. As such, I’ve included it within this post since it’s clear the software is being constantly updated.)
o Maximum Trainer também acho que cumpre o que pretendo. não consigo decifrar é se gratuito ou pago. mas parece ser gratuito até à versão beta e pago após essa versão.
