How many watts do I need to ride with Coco on Zwift?

Multiply your weight in kg by 2.6. A 70 kg rider needs 182 W. An 80 kg rider needs 208 W. Use the calculator on this page for your exact number based on your weight.

What W/kg is Coco on Zwift?

Coco rides at 2.6 W/kg. All RoboPacers weigh 75 kg and are 175 cm tall, which puts Coco's raw output at 194 W on flat terrain.

Is Coco good for Zone 2 training on Zwift?

It depends on your FTP. For riders with an FTP around 2.9–3.5 W/kg, Coco sits comfortably in Zone 2. If your FTP is closer to 2.6 W/kg, Coco becomes more of a threshold session. The 2.6 W/kg figure is your flat-terrain target — drafting mid-pack typically reduces actual effort by around 25%.

Why does Coco's group feel harder some days than others?

Group size has a big effect. A large peloton creates a strong draft, making it noticeably easier to stay with the pack. On quieter days with a smaller group, the reduced shelter means you'll feel the effort more. Route terrain also plays a role — Coco uses dynamic pacing, pushing up to 10% harder on climbs and easing up to 20% on descents.

What is the story behind Coco's name?

Coco was originally called C. Cadence when Zwift's pace partners were named after their race categories. When the pace partner system was redesigned in 2022, the old names were dropped — but Coco kept the name the community had already given her. She's the only original pace partner still riding.

Meet Coco

★ Fan lore — unofficial & written for fun

Coco has been on Watopia's roads longer than most riders can remember. She started out as C. Cadence, back when pace partners were named after their race category, but the community started calling her Coco and it stuck. She's the only original pace partner still riding. Her 2.6 W/kg sits in a range where you're actually working but the group around her is still enormous. A proper peloton that somehow also functions as a social event. If you've earned your "Bigger Than Jensie" badge (100 Ride Ons in a single session), there's a good chance Coco's pack is where it happened.

Who suits Coco

Coco is neither a beginner's easy spin nor a proper sufferfest. That's probably why her group is always packed.

For riders building an aerobic base, 2.6 W/kg sits in Zone 2 to low Zone 3 for most people with an FTP around 2.9–3.5 W/kg. You're working, but you're building rather than destroying yourself.
People coming back from a break get a real effort here without the ego hit of sliding off a harder pacer immediately. Coco holds a pace most people can sustain if they concentrate.
Anyone targeting Yumi (2.9 W/kg) as a next step. Spend enough time with Coco and Yumi stops feeling like a different sport.
Social riders. The group is usually big, the Ride Ons are constant, and you'll see different faces every session.

If Coco feels too easy most of the time, Yumi is waiting. If she occasionally drops you but you can get back on, that's probably the right place to be for now. The gap between almost-holding-on and comfortably-in-the-bunch is where most of the adaptation actually happens.

What to expect in Coco's group

The group around Coco changes the actual experience quite a bit, separate from the pace itself.

Group size

Usually the largest in Zwift

Draft benefit

Strong — ~25% mid-pack

Ride Ons

Thumbstorm — best in game

Dynamic pacing

+10% climbs / −20% descents

Because Coco's group is usually large, your average power through a full session tends to come in well below the flat-terrain target. That's the draft doing its job. The number from the calculator above is what you'll push when you're off the front or hitting a climb. Mid-pack on a flat stretch is noticeably easier.

Routes rotate week to week. Tempus Fugit is a clean watts-only session. A route with real climbs brings terrain variance and surges in the group. Worth checking the RoboPacer schedule before you join so you know what you're getting into.

Common questions about Coco

How many watts do I need to ride with Coco?

Multiply your weight in kg by 2.6. A 70 kg rider needs 182 W; an 80 kg rider needs 208 W. The calculator at the top of this page does it for you. That figure is the flat-terrain baseline. Drafting mid-pack usually cuts the actual effort by around 25%.

Is Coco good for Zone 2 training?

Depends on your FTP. Around 2.9–3.5 W/kg, Coco is Zone 2. If your FTP is closer to 2.6–2.8 W/kg, she's more like a threshold session. A rough check: if you can hold a conversation for a full hour at Coco's pace, you're in Zone 2 territory.

Why does Coco feel harder some days than others?

Mostly group size and route. A 100-rider peloton creates far more draft than 15 riders. On busy days Coco can feel easier than your target watts would suggest; on quieter days you'll feel every watt. Terrain matters too. Coco uses dynamic pacing and pushes harder on climbs, backs off on descents. If you're used to flat sessions, a hilly route can catch you out.

What's the story behind Coco's name?

Originally she was C. Cadence, named after her race category. When the pace partner system was redesigned in 2022, the old category names went. Coco was what the community had already been calling her, so it stayed. She's the only original pace partner still on the road.

Can I earn the Bigger Than Jensie badge with Coco?

Yes, and Coco's group is a good place to try for it. The badge needs 100 Ride Ons in a single session. With one of the biggest groups in Zwift, the thumbstorms are pretty much constant. Join during a busy period, sit mid-pack, give out Ride Ons yourself. Plenty of riders have picked up that badge on a Coco session without really planning to.

When should I move from Coco to Yumi?

When Coco feels genuinely comfortable rather than just survivable. If you finish a 60-minute session thinking you had more in you, that's probably your cue. Your FTP is likely sitting above 3.0 W/kg at that point. Yumi is only 0.3 W/kg harder on paper, but the smaller group means less shelter and the jump feels bigger than the numbers suggest. No real reason to rush it.
