How To Set Up Erg Mode On Zwift

[Writer'due south notation: I originally wrote this piece internally for Zwift, only it seemed a bit too technical. I remember that makes it perfect for Slowtwitch. However, it should be noted that I work for Zwift, and that's why it'due south so Zwift-centric. But Erg Mode is non at all unique to Zwift. Virtually all major training platforms will support this. As practise most good headunits that can control a smart trainer. I but don't use those other platforms. But from a "when/how/should I use ERG fashion?" perspective, the Zwift aspect of this is entirely irrelevant. I have my obvious biases, but Erg Mode is by no means a special or unique feature.

I wrote this about the same time that this thread - "Why you need to quit ERG mode..." - appeared on our forum. I didn't write it in response that thread; it was just a happy coincidence. This is the much longer version of the answer I gave in in that location.

Erg Mode - bachelor when using Zwift in Workout Mode with a compatible "smart" trainer - ways that the trainer will adjust the resistance the trainer applies in order to help maintain the prescribed power of a given interval. Erg mode is a reference to the CGS unit of measurement of energy - the Erg - which is 10-7 joules or, approximately, the amount of energy used by a common house-fly to practise a push-upwardly.

Humans generate power on a cycle by applying a force to the pedals. Because the pedal is at the end of the crank - a lever-arm - this force generates a torque which drives the system via the chain and sprocket. There are two ways to generate more ability, which is divers every bit a unit of measurement of work within a menses of time. You can either utilize more force in order to exercise more than piece of work - pedal harder - or you tin subtract the unit of time it takes to complete that unit of measurement of work - pedal faster. Erg Mode works by adjusting the resistance up as your cadency drops - significant you demand to generate more forcefulness - or by decreasing the resistance as your cadence increases - because you are doing your work more quickly.

How rapidly this change happens varies from trainer to trainer, and is somewhat limited by how oftentimes Zwift and the trainer communicate. Zwift also does some work behind the scenes to smooth things out and to continue the changes from existence too drastic in one direction or another. For this reason, Erg Mode ofttimes is not a keen choice for workouts with a lot of very curt and very large changes in power. But practiced smart trainers respond quite quickly, and I find that Erg Mode works well for intervals equally curt every bit 20 seconds; annihilation shorter than that and you probably volition want to have intendance of things yourself by shifting and how hard you pedal.

Erg Mode is the default option for Conditioning Manner in Zwift, so if yous've never actually paid attention to whether or not Erg Mode was on or not, you may have been using it this whole fourth dimension without always knowing. For near typical workouts - things like SST or The MCarthy Special, Erg Mode works simply fine. Every bit with (virtually) every approach to grooming, there are those who insist that it has no place in "proper" training and those who insist it'south the only way to train indoors. Again, every bit with most every approach to training, the truth is somewhere in betwixt.

The "opposite" of Erg Manner in Zwift is Incline Way; Incline Mode allows y'all to manually set the resistance of the trainer to be equally difficult - or as easy - as you wish. When you're just riding around in Zwift not doing a workout, you are in Sim - or Simulation - Mode, where Zwift is telling the trainer what the slope is of the road that you're on (or, more than precisely, the gradient of the road yous volition be on by the fourth dimension the trainer gets the message Zwift is sending). If y'all turn Erg Mode to Off using Zwift Companion or the blue Control Strip, you'll meet another fix of Up/Downward arrow buttons appear; these permit you to increase or decrease the resistance of the trainer (shown every bit an orange, vertical analog scale to the correct of the HUD). When Erg Way is On, the trainer will change its resistance automatically based on the target power of the given block. (If y'all're in a Gratis Ride block, you will almost ever exist placed into Incline fashion unless your coach or the workout author has set up it upwards to preserve the terrain of Zwift.) Neither Erg Mode nor Incline Mode is either "amend" or "worse." And to the larger point, doing formal, structured workouts is also non better or worse training than riding around or racing. The key is using the tools at your disposal to help you accomplish the grooming stimulus yous are seeking.

Erg Style is simply another tool to put in your training toolkit. For a lot of people, Erg Mode is only simpler, considering it does a lot of the thinking for y'all. If you like to just tune out - especially during very long blocks - Erg Mode is keen. But just thinking of it every bit a style to make it easier to think less is to shortchange all the means that it tin can impact your training. I really started thinking more almost how - and when - to employ Erg Way when I switched from being a triathlete - where the grooming is pretty monotonous, more often than not long, and fairly steady. Long altitude triathlon cycling is, equally Mark Allen liked to say, "an exercise in who tin whisper the loudest." Information technology's supposed to be very steady. That sort of training probably doesn't matter also much when it comes to Erg On or Erg Off; I'd actually say that there's a slight preference to having Erg Off because it's really important to develop the skill - and it is a skill - of pacing yourself evenly and steadily across a long period of time and - especially - across variable terrain. Cadence is also not specially important for triathletes and, if anything, there'southward a preference for lower cadences where neuromuscular coordination is rarely - if e'er - a limiter.

But when I started training on the track, cadence became a much more important element of performance. On the runway, with a single, fixed gear, cadence and power and speed are all inextricably linked. And information technology was because of this that I really started to delve deep into how all-time to apply Erg Mode.

For workouts where cadence is the fundamental parameter, employ Erg Mode. If you have to focus on both the power and cadence, it'south difficult to do either well. If hitting a specific cadence is important - and there is compelling enquiry that high-cadence pedaling is a specific skill that you demand to train, and so using Erg Mode is a corking way to make sure y'all hit that. Interestingly, I'd say it'south particularly for high-cadence workouts that Erg Mode is most beneficial; for depression-cadence workouts it can become either way. For really low-cadence workouts, Erg Mode may actually be problematic because it can be like shooting fish in a barrel for the resistance to fasten and then high every bit to lock the trainer upwardly or if yous spike the ability even a bit the trainer resistance can drop off making it harder to stay on the cadency. Typically, for really low cadence workouts, I volition use Incline Way and just dial the resistance upwardly to a level where I can find a adept rhythm. Merely at high cadency - especially if the power is too loftier, I observe that Erg Mode can really allow me to hit a cadence and power that I'd struggle to if I had to focus on both.

Many people call up of Erg Mode as a tool to keep your power from dropping, simply it'southward also at to the lowest degree as important as a tool to go on your power from spiking. Erg Fashion is but equally useful when it comes to keeping you from riding too hard equally it is when it comes to keeping you from riding too easy. Especially early on in a long ride or early in a loftier power interval where you might start with a big fasten in the power, Erg Mode tin can be invaluable in terms of keeping a lid on your power. In particular for very high power efforts where it'southward very difficult to pace them evenly - you'll want to start out likewise hard at the outset and desire to fade at the end, Erg Way can help to proceed your pacing even. Erg Mode can also exist good for keeping those of us with competitive streaks in check when someone rides by u.s. at a time when we're supposed to be riding forth at base of operations.

On the flipside, sometimes it'due south important to exist able to make a big surge and then settle in. Or for very short efforts where the power cannot be sustainable - similar a dart. In these cases, Erg Way runs counter to the manner that our torso works, and it should non be used. Sprinting in Erg Way is extremely counterproductive - the resistance won't exist high enough at the get-go and will be much as well loftier past the time your legs inevitably starting time to fade.

1 of the major criticisms of Erg Manner is that it prevents y'all from learning how to pace yourself properly; only Erg Mode tin can actually exist the single best mode to teach yourself to step evenly (which is really what people mean when they say "properly") because information technology helps y'all actually experience what it'southward like to maintain a steady ability - particularly when coupled with a target cadency. Information technology allows you to experience something that you might struggle to understand at starting time. In that same fashion, Erg Mode tin also be a swell reminder to keep your power in check and to prevent too much ability - something that'due south far more detrimental in long races than too little power - by immediately dropping the resistance if you start to fasten the force on the pedals.

Ramp Blocks in Zwift also present a unique experience when coupled with Erg Mode that can be hard - if not impossible - to replicate outdoors. By slowly ramping the power up or downwards, Zwift tin can assistance guide you to actually increase the power as your fatigue builds or to help you drib your power in a controlled mode over the class of an interval. Decision-making this precise step up or step downwards in power is something that can exist virtually impossible to do outside because of terrain and weather. Even in Zwift, without Erg Fashion, these precise ramps up - and downwards - are nearly impossible. This type of stimulus is something that's unique to the Ramp + Erg Mode pairing.

Especially with the introduction of Workout Mode in Zwift Companion, it's really easy to turn Erg Mode on and off and to experience the difference in how information technology makes a workout feel. One interesting experiment tin be to do 2 sets of a given block of intervals spaced out with a long rest block between and to see how you experience if you do the first circular with Erg Way on and how you experience if you practice the get-go circular with Erg Mode off. Only the biggest benefit volition really come to thinking more about how Erg Mode can interact with different workout elements and build workouts - and engage and disengage Erg Mode inside it - to put a new spin on your training. Don't just set information technology and forget; make how y'all employ Erg Mode a conscious decision in your approach to structured training. For me, it has made grooming both more productive and more than enjoyable (in that type-2 fun way).
