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:

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.
