How to run a Kayo watch party for the Grand Prix

Races that start at one in the morning are better shared. Open Kayo or Fox Sports, share one link and the room stays on the same lap.

Half the calendar reaches Australia in the middle of the night. Whoever stays up for a European race is usually the only person awake in the house, and the group chat is asleep.

CoViewer is a free extension made by BoxBoxd. It holds every picture on the same second and puts a chat beside the video. It never rebroadcasts anything, so each person watches on their own subscription.

The setup, six steps

1

Add CoViewer to Chrome

It is free and it takes one click from the Chrome Web Store. There is no account to create, no card, nothing to configure. The extension does nothing until a race is on your screen.

2

Open the race on the broadcast you already pay for

F1 TV, Canal+, Sky Sports, DAZN, ESPN, Viaplay, Apple TV, RTL, Kayo, Fox Sports, Sky Italia, NOW, WOW, YouTube or Twitch. Everyone in the room keeps their own subscription and their own commentary language. Nothing is ever rebroadcast.

3

Let it recognise the session

CoViewer reads the page title and the player to work out which Grand Prix and which session you opened. When it is sure, the launcher appears at the edge of the video. If you are watching something else, it stays quiet.

4

Create the room and copy the link

One click creates the party and gives you a short link. Send it in the group chat, by message or by mail. The room is yours, you are the host and playback follows you.

5

Your friends open the link

The link explains the two steps, adding the extension and opening their own broadcast. They join with the same code and appear in the room within seconds, wherever they are and whoever they watch with.

6

Watch the race together

The sidebar opens next to the video with the chat, the reactions, the live standings and the room. At the flag you rate the race and pick your driver of the day and it posts to your BoxBoxd profile.

The detail that counts here

The room works the same on a replay. If the party watches Monday evening instead of Sunday night, everyone shares one timestamp and the spoilers stay out of it.

How does the sync hold?

The host sends the playback position to the room every three seconds. Each viewer compares that position to their own player and corrects the difference quietly.

A gap under two seconds is closed by nudging the playback speed by five percent for a moment, so nobody sees a jump. Past two seconds the player seeks straight to the right place. On a live broadcast only play and pause travel, because a live stream carries its own clock.

Ad breaks are handled too. When one person hits an ad break, the room waits and resumes when everyone is back on the race. That single detail is what usually breaks a watch party built for films.

What time the races start in eastern Australia

Of the 23 races on the 2026 calendar, 8 start before nine in the morning in eastern Australia and 13 fall between ten at night and six in the morning. The earliest is the British Grand Prix at 00:00, the latest the Monaco Grand Prix at 23:00.

Those are the weekends where a group watches alone by default, because the people who would normally be on the sofa are asleep or three time zones away. A room is the cheap fix, since everyone keeps the feed they already pay for.

Frequently asked questions

What time does the F1 race start in eastern Australia?

It moves with the calendar. Across the 23 races of 2026, 8 start before nine in the morning local time and 13 run between ten at night and six in the morning. The earliest is the British Grand Prix at 00:00 and the latest the Monaco Grand Prix at 23:00.

Can you watch F1 with friends on Kayo?

Yes. Each person opens the race on their own Kayo account, one person creates the room and shares the link. The CoViewer extension keeps the players in sync.

Do we all need the same subscription?

No. Everyone watches on the service they already pay for, in their own language. Only the playback position travels between browsers.

Is there a limit on how many people can join?

No and the extension and rooms are free.

CoViewer is free, it takes about a minute to set up and it runs on the broadcast you already pay for.

CoViewer is made by BoxBoxd, the motorsport social network where fans rate every Grand Prix. The extension keeps playback in sync between people who each watch on their own subscription. It never rebroadcasts a stream. Questions at partnerships@boxboxd.fun.
