Heavy riders

Just wondered if there are any riders out there over 100kg, who zwift’s and if so, what sort of numbers are you achieving? For example duration of rides, w/kg, watts woekouts etc.

I’m currently 121kg, down from 131kg over the past 6 months since ive started zwifting and getting healthy again.

Currently have an FTP at 247 and can hold 230 to 240 watts for 30 to 40 minutes. My FTP started at 170 after doing the FTP test. Im 38 and stocky build and love my food and trying so hard to eat well so i can say i dont eatthe best right now.

Any comments will be appreciated just so i can see where my fitness is compared to others and how i can improve (i know my diet) haha.

Cheers, Chris :+1:

There are a lot of heavy riders on Zwift. Their power is all over the map since their mass doesn’t tell you about their body composition or fitness. Some of them are absolute beasts, others are just normal folks who happen to carry some extra weight, and some are quite fit but not “cycling fit” - strong but lacking endurance that usually comes from a lot of hours on the bike.


Recommend cross training- walking, running, swimming…

Cheers Paul. All good, I was just reaching out to see if some people were simular to me because I hardly seen chats or starts or anything baae on heavier riders.
Thanks for your reply buddy :+1:

Cheers :+1:

One way to compare would be to look at race results on zwiftpower.com for D category. Look for races with a large number of D category riders (the number in the yellow bubble for that race). Click on a race with a lot of Ds in it, then filter for just the Ds, click on the Watts button (instead of W/kg) and look for people near your size. You shouldn’t need to look at very many races before you find some people in the neighborhood of your size. “Stage 1: Race the Worlds—Rolling Highlands” events should be a good source of data since the D field is fairly large in those and those events are held many times each day.

Alternatively register with ZwiftZpower, if you haven’t already, and you can search under ‘Rankings’ for all cat Ds who weigh 100kg or more and check out their power/FTP metrics.

If I may add, you are doing really well with your weight lose and 6 months of regular exercise. Hopefully it will be a long forever journey which you will come to embrace.

On a previous forum post I think you were looking for advice on losing weight and you hopefully received useful feedback.

If you wish to compare yourself against others, not just those over 100kg, a metric used on Zwift is to divide your FTP by your weight. In your current case that is just over 2.0 w/kg. A good solid starting point and a place many Zwifters would like to be at.

If you can lose a little more weight, I know your target is 100kg, and gain a little more power you will be at the top of race category D <2.65w/kg [race categories D up to A] and that is a good target, especially if you wish to try racing on Zwift, health permitting.

Whatever you have been doing the past 6 months is working, enjoy it and keep it up.


Hi Ian, sorry for the late reply. Appreciate your reply and thanks for giving the time to say positive things it has added to me being able to keep going and getting the workouts in.

Wishing you all the best on the bike :+1:

Nice work - stay at it.

A couple years ago (beginning of COVID) I was 135, now I hover around 100kg. We have similar performance numbers.


My FTP is 287 and I’m 109kgs. I was 134kgs when I started Zwift. I really only look at Zwift as a training tool with structured workouts. While there is some correlation with Zwift to outdoors, but it’s not an exact science as I drop people outdoors that drop me in Zwift.

For what it’s worth in the outdoor season I don’t have much structure to my riding and ride about 250-300kms a week.

The weight continues to come off slowly, but I’m in no rush to lose 40 kgs “quickly” so I can brand myself a different class of rider on Zwift.

You sound like my twin. 124 kg, FTP of 246 right now. I’ve had my FTP bounce between 245 and 260 on and off for the past two years due to inconsistency in training and diet.

In the summer, I’ll tackle multiple rides of 100km in events and solo, but generally my indoor rides max out around 2 hours. This is mostly due to my trainer being set up in the living room and having two small kids, so can’t spend all day on the bike.

The main things I’m aiming to improve on (not perfect) this winter is consistency in training and fueling. I’d like to get down closer to 110 kg for next year’s riding season, but I know that it doesn’t have to happen all at once - more like 0.5 kg/week to try to make it sustainable.


I’m 108kg (181,cm) and for some reason I can’t motivate myself to climb on the bike (indoor and outdoor). I only commute on my normal bike, but I do not count that as a exercise.

I’m aware of the the extra things, besides cycling, I have to do to lose weight. What do you do extra to lose weight?

For me it worked to calculate my deficit.
You earns- 500~750kcal with an hour racing.
To have a 1000kcal deficit per day it was way easier to have a decent filling meal.

Also I like to improve, it was very motivating to see my segments improve. Especilly the climbing segments improve very quick with every lost kg.

Perhaps (when Zwift is your sport to go, or else choose another sport) join a club, WTRL racing league, where you sorta commit of cycling every week.

If you like “nerding-out” you could do WTRL and the recon-rides before the races, then you have already 2 sessions under the belt.

I like nerding out, so for me a Garmin watch, counting kcal (going in- fatsecret) measuring kcal used and improving on Strava segments worked for me. I took me more then a year before I was brave enough to put me into Lycra before cycling outside

Hope this helps?


It’s less faff than cycling so you can be ready, run and showered really quickly.

For any given time window it’s more energy-intense than cycling so you burn up more calories.

I lost 6kg this year through running - and I started at 76kg.

Just start slow. Look at a couch-to-5k program.

LOL, I like nerding-out too. Garmin watch, power meters on my 2 roadbikes :wink:

BTW, I started outdoor cycling 20 years ago and started wearing lycra right away :joy: Normally, I ride 6000/ 7000 km per year on my roadbike outdoors, but this year there was little motivation. Not sure why that happened.

this is true short term but you are probably ,more able to cycle more regularly and for longer time periods. I used to run a bit but my knees fell apart so had to stop.

what ever makes you move as often as possible and you enjoy is usually the best thing. that will be different for different people and is probably a mix of stuff.

Starting riding as a commuter, just a couple of miles to work and then the return trip. Kept improving, over the last year I mixed in some indoor training and bought a trainer a month ago. 107 Kg down from 122 Kg’s and FTP of 317 up from about 200 a year ago.

Dang i feel like a snail lol. 277lbs (126kg) and i just did an FTP as i am 13 weeks out from my first sprint Tri. I managed a 144. Granted i am new to a bike and over all down from 372 (169kg) 9 months ago so theres a lot i can gain pretty quickly. But it has at times made to where i cant even pedal even if i put my full weight on the pedal, not sure why.
