Start & Finish
If you choose this route, the game will spawn you on Constitution Hill near Buckingham Palace, riding in what is typically the reverse direction (westward). Since riders are placed at various points near Buckingham Palace on Constitution Hill, we chose to start our Strava segment at the Classique banner which is approximately 1.5km from the spawn point.
Events begin at the start pens, giving you approximately a 7.5km lead in to the Classique banner where your lap officially begins.
Achievement Badge: 500 XP

A free ride of Greatest London Loop begins on the Classique route in the reverse direction, but only covers a portion of it before turning onto the Greater London roads. You are then taken over the bridge, through the subway and into the “Richmond Park” countryside which was part of the January 2018 London expansion.
The subway tunnels carry you back into London, over the bridge and through the start/finish banner on the red pavement of the Classique.
Can you create a segment for this that runs from the pens
Done! Linked above.
Hello, I did two loops to log 325m of elevation while riding for 45km distance. However, the loop is more 123m of evelation instead of 163m. I had to lower my expectations and go longer to reach at least 250m 😉
I just checked and the actual route elevation gain says 147m (so between your value and our old one!) I updated it above to match.
Is there a way, when doing a ride to watch your riding showing where it climbs up and down?
The bottom of the mini map has upcoming elevation, but the best view is with the Zwift Power live view open on a 2nd display
Neat! Can you label key areas?
Today completed route plus lead-in in 25.4 km & 130m elevation
Thank you.
I think the Greater London Flat lead-in is much shorter now. Finished my ride and got my badge at 24ish km
You were commenting on Greatest London Flat, not Greater London Flat 🙂
Also, notice that the lead-in depends on whether you do a free ride, a meetup or an event. The events have a much longer lead-in from the starting pens in the northeast corner of the map…
Road 21.5 miles and didn’t earn the route badge. I think the lengths are off. 14.7+4.7 = 19.4 so should have earned the badge.
Same issue today. Im sad.
I just rode this today and the lead in was .4 miles or so. I wasn’t convinced I was on the right course and left and respawned in the same place. An update?
This route is broken. Today I rode 35 km and did not get the badge for route completion. Anyone else having this issue?
Yes, I did 38km today!
I did 47 kms didn’t get the badge turned around at box hill still didn’t get credit went around and around in the middle. I badge 🙁
Oops still no badge or credit
How can I select this in Zwift? I am doing Gran Fondo 6 weeks work out, and want to do this as free ride
Easiest way is to ride it on a day when London is scheduled, like today: https://zwiftinsider.com/schedule/
