A few weeks ago, with Summer turning to Autumn, the wind getting up and the sun going down, my thoughts turned to Winter cycling. I’ve been considering getting a turbo trainer for a while now and I originally ordered a Jet Black Z1 Fluid Pro until I saw a smart trainer on offer at Wiggle for about £85 more than the “dumb” fluid trainer I was going to get… added to which I got nearly a tenner’s cashback via TopCashback…
The trainer I’ve gone for is a Tacx Vortex and it’s proved pretty easy to set up. Ideally I’d use a spare wheel with a trainer tyre but I don’t have one and my tyres are already looking a bit worn – I may change them when the bike comes out again in the spring, meaning I can afford to wear them out on the trainer first! All I had to do was swap out my quick release skewer for the one that comes with the trainer and my bike was easily mounted.
Calibration was a simple case of using the Tacx Utility app on my iPhone – which finds the trainer via Bluetooth and can also be used for firmware upgrades (it’s available for Android too). All you have to do is cycle up to a given speed and away you go!
I found that the Tacx Utility would always locate my trainer but the Tacx Cycling app was less reliable. Ultimately that’s not a problem because I use the Zwift virtual cycling platform (more on that in a moment) and the Zwift Mobile Link app will allow the PC to find my trainer via Wi-Fi and Bluetooth. There is one gotcha though – on the second time I used the trainer I spent a considerable time trying to get things working with Zwift. In the end I found that:
- The Tacx apps couldn’t be running at the same time as Zwift Mobile Link.
- My phone had a tendency to roam onto another Wi-Fi network (the phone and the PC have to be on the same network for the mobile link to work).
- My Bose Soundlink Mini II speakers were also interfering with the Bluetooth connection so if I wanted to listen to music whilst cycling then a cable was needed!
I’m guessing that none of this would be an issue if I switched to ANT+ – as my Garmin Edge 810 does. The trick when using the Garmin is to go into the bike profile and look for sensors. Just remember to turn GPS off when using it on a stationary bike (or else no distance is recorded). Also, remember that:
“[…] when doing an indoor activity or when using devices that do not have GPS capability, the [Garmin Speed and Cadence Sensor] will need to be calibrated manually by entering a custom wheel size within the bike profile to provide accurate speed and distance.” [Garmin Support]

And, talking of ANT+ – one thing I couldn’t work out before I bought my trainer was whether I needed to buy an ANT+ dongle for Zwift? Well, the answer is “No”! as the Zwift Mobile Link app works beautifully as a bridge on my trainer – it’s worth checking out the Zwift website to see which trainers work with the platform though (and any other gear that may be required).
I’ll probably write another post about Zwift but, for now, check out:
In the meantime, it’s worth mentioning that I started out riding on a 14 day/50km trial. I was about to switch to a paid subscription but I found out Strava Premium members get 2 months’ Zwift free* and, as that’s half the price of Zwift, I’ve upgraded my Strava for a couple of months instead!
So, with the trainer set up in the garage (though it’s easy to pop the bike off it if we do have some winter sunshine), I can keep my miles up through the Winter, which should make the training much, much easier in the Spring – that’s the idea anyway!
*It now looks as though the Strava Premium-Zwift offer has now been limited to just November and December 2016 – though I’m sure it will come around again!
