Allen is a big proponent of using Zwift to determine your functional threshold power (FTP), a strong metric of fitness. You’ll need a power meter or a trainer that can estimate power, like Kinetic’s Smart Road Machine (pictured above, with the add-on Power Unit).
FTP tests are used to identify the likely max power you can reasonably hold for an hour-long time trial, usually calculated while you put out your highest sustainable power for 20 minutes.
After doing an FTP test – available through Zwift’s online menu of workouts – you can use your result to set up training zones that allow you to work toward specific cycling goals, such as riding faster, further, or both. With Zwift, if you want to increase your power in certain conditions, you can choose to ride hillier courses, longer distances, etc.
Once your set-up is dialed, it’s time to choose a course and get pedalling.
There are currently five worlds in which to ride: Watopia, also known as Zwift Island; a true-to-life route around London and some of the surrounding countryside; an online version of the 2015 World Championships course in Richmond, Virginia; Innsbruck, Austria, a world built around the 2018 UCI World Championship cycling course; and New York 2118, which is modelled on the roads of Central Park as they will be in 100 years along with kilometres of skyway, flying cars, and futuristic buildings.
These worlds are constantly being expanded by the Zwift team. Earlier this year, Zwift added both the Alpe du Zwift on Watopia, a Zwift-ification of the Alpe du Huez climb accessible only to Zwifters at level 12 or higher, and the Leith Hill expansion to London.
“They’re all unique in terms of course demands,” says Allen. “And that’s part of the appeal. You’re not doing the same loop over and over.”
For example, Watopia has one main climb, a few rollers, some downhills, and plenty of flats. There are various choices along the way: Turn one direction to practice climbing, head the other direction for more flats. This diversity means you have plenty of opportunities to personalise your route and training, making it longer or harder in certain ways.
The 14.9-km London loop has 220 metres of climbing per lap, while the Richmond circuit is mostly flat, save for a pair of precipitous cobblestone climbs that require arduous out-of-the-saddle efforts (which can be great if you’re interval training). You can find a monthly schedule on the Zwift blog.
Other recently added features include avatar customization so your Zwift persona can look just like you with options for skin colour, hair colour, facial hair, and even preferred sock length. The game also has a mini map feature that allows you to track your place in any Zwift environment as you ride, as well as proximity to sprints, KOMs, and other climbs or descents. And you can sign up for Zwift flexible training plans, which can be tailored to your goals and available training time. This allows you to progress logically, as you need to put in the work to unlock later workouts.
Also to note, if you’re a multi-sport athlete, Zwift also recently launched Zwift Run, which allows users to take their treadmill experience shoulder-to-shoulder with cyclists on the roads of Zwift. Users need access to a smart, Bluetooth-enabled treadmill or a ZwiftPod (or similar footpod) to connect into the game.

Perhaps best of all, Zwifting means you never have to ride inside alone. Right now, interacting with other riders means riding alongside their avatars, and tapping out a quick message on your smartphone screen or laptop keyboard. (Increasingly, though, popular apps like Discord are now allowing riders to talk to each other in real time. “Eventually everyone will have a microphone,” predicts Guerra.)
And just as with outdoor group riding, Zwifting is governed by rules of etiquette. The most basic edict is simply, don’t be a jerk.
If a group ride has a pre-determined pace (typically indicated by a watts-per-kilogram number), don’t jump in and start smashing heads. Most group rides will have a leader, indicated by a beacon over his or her head. Follow this person’s lead and you’ll fit right in.

The same ethos applies to the myriad Zwift races available to users. Just like in the real world, nobody likes the Cat 1 rider who sandbags the Cat 3 race.
“That just ruins the race for everyone,” says Nathan Guerra, a Wisconsin-based pro mountain biker and frequent Zwifter, who has made a name for himself as the unofficial voice of Zwift; you can hear his live-caster play-by-play calls of various Zwift events on a Twitch.tv video stream. “If you know your FTP or at least an estimation, you’ll know what races make sense for you.” (For a list of upcoming Zwift races, check out the third-party website zwiftpower.com.)
Guerra also discourages outright cheating where, for instance, you lie about your weight in order to increase your watts per kilogram. Go above 5 w/kg and you’ll get flagged by ZADA (short for Zwift Anti-Doping Agency) and need to provide specific “in real life” ride data to get Zwift-approved. And no, this is not a joke. ZADA is a real thing managed by volunteers from the Zwift racing community.
Fortunately, the vast majority of Zwifters log on simply for fun and exercise. And the more you ride, the more chances you have to meet new people – and unlock equipment and jersey upgrades.
