Route Description

Route profile by ZwiftHub – the place to plan and track your route achievements!
Beginning at the start pens, you will travel a clockwise loop across the Tower Bridge then into The Underground, which magically delivers you to the rolling “Richmond Park” area of Zwift’s London map.
Enjoy the open air as you ride this road in a direction not commonly taken in other London routes. Soon enough, you’ll be climbing up out of The Underground to cross the Thames once more and ride along its edge back toward the lap start/finish banner.
This route’s lap banner isn’t the typical London lap banner. Instead, it’s located at the start of the Tower Bridge. You’ll see an actual arch here in particular events, but you can also always see a white line on the road at this location.



Is there ever an event on this route? I want it!
First event is TdZ: https://zwiftinsider.com/tour-de-zwift-2025/
So when will this route actually be available to ride for the badge (when is TDZ 2025)?
See https://zwiftinsider.com/tour-de-zwift-2025/
Is there going to be some weird custom finish on this route? Its 7.5 miles, but the TdZ events claim its 10.8 miles, which would put the finish half way round a second lap … but the only natural banner on the route is the London Loop line (unless there’re adding in a second start pen up near the mall!)
Nah – just Zwift’s TdZ info was incorrect. I just clarified it with them, and updated the TdZ post (https://zwiftinsider.com/tour-de-zwift-2025). 12.4km loop…
Is the elevation information correct? The article says the route is near pan-flat but the top box says 115 m of elevation.
Yeah, elevation is correct.
Hey @Eric Schlange will any of the newer and future new routes be getting route profiles on ZwiftHub? I find those to be by far the best route profile images with the particular ratio they use for length/height info, but haven’t had any for new routes for quite a while now ðŸ˜ï»¿
…actually, I see that Coast to Coast has one of those now, so fingers crossed other courses without are “coming soon”
They’re pretty much all there now, I think.
Pretty bad/misleading name when there is more elevation than in Greater londo.n flat..
How do I know what category to sign up for? I am new to Zwift.
Zwift will recommend a category for you.
Why is there no Veloviewer leaderboard for this route?
There is – see it here https://veloviewer.com/zwift-insider/london
Quick note – the Route Description picture is showing the wrong route
Odd. Fixed!
