Route Description

Starting from the London lap arch, we travel west on the well-worn road along the Thames, following the “Greater London” loop counter-clockwise before turning into the Classique for a loop in the reverse direction.
After finishing the Classique reverse sprint, we turn left at the roundabout to head back onto the Greater London loop in the other direction, coming back to the Thames for a bit before turning right to cross the bridge to the Underground station.
Exiting the station, we’ll stay left to the finish, taking the flattest roads around to the other Underground station before crossing the Tower Bridge and finishing our lap.
I hear The Clash.
I saw the Clash!
You can just about listen to the whole album at 2w/k 😆
Sigh. Yet another event only course
If past practice is anything to go by, it will be event only until used in the Unlocked event, and will then be opened up to be freely rideable.
I wish Zwift would give this world some love. Instead we get more NYC…
Me too
To be fair, NYC was in real need of something as well. Would be interesting to see riding stats for the different worlds but I would imagine NYC rank lower than London.
The problem with NYC is that it is weird. It’s the most fictional of all and I believe NYC deserves better than glass roads in the sky.
NYC would be more interesting if the glass roads had a CRR of 0.00001.
IMO, NY and Yorkshire offer the thougest races in Zwift by nature, while London is a much more friendly World to free riding and social events. I do agree with giving NY a more friendly expansion, as I would strongly advice to give Makuri a climbing hub. London would be next in line, but it has almost everything in place.
Noticed some new badges yesterday which quickly disappeared. What do we know about these?
Avon Flyer
Double Parked
Double Span Spin
Fuhgeddaboudit
Green to Screen
Issendorf
No Sleep till Brooklyn
Prospect Park Loop
Times Square Circuit
Toefield
Watts the Limit
Those sound like the new New York routes that they told us about.
Is it double XP points?
