Route Description
Events on this route begin in the Times Square start pens with a lead-in to the circuit arch which serves as the route’s start/finish line.
After you hit the arch for the first time, you’ll complete a full Times Square Circuit Reverse (which awards an orange jersey to the fastest time on course), then head into the City Hall Station subway.
(This subway, the middle of the three added in Zwit’s NY map expansion, is inspired by the IRL City Hall Station, a decommissioned station located beneath City Hall in Lower Manhattan. Its distinctive brick arches echo back to yesteryear.)
This subway includes 10-second Power Segments in both directions, so anytime you’re here, you’ll get a chance to improve on your 10-second power PB.
Climb out of the subway and you’ll turn right to begin the Brooklyn Bridge KOM. While not particularly steep or long, this is the biggest climb on the route. Finish it, descend the other side of the bridge, then you’ll turn around and head back across the river via the Manhattan Bridge, which includes a short sprint segment with a finish line at the apex of the bridge’s arch.
Now it’s time to head back to the finish at Times Square. You’ll descend back to the City Hall Station subway, ride through another 10-second Power Segment, then climb out and onto the glass roads of the Times Square Circuit for what’s almost another full lap of the reverse circuit. Nice work!
Any chance you can release the course descriptions? It might be nice to have a little time to preview before the actual races / rides.
You have to wait until the second set of races! 🤣
Nice course! And if you like the “escalator” into and out of the Underground station in London you’ll love this. There are 2 subway sections with a very steep drop/climb escalator at each end. Shorter than London but steeper. The last climb out comes just a couple of k from the finish so a great launchpad for a long-range attack. Go hard up it and keep going – you’ll catch lots of folk unawares
The escalator is counter-intuitive. When you reach the top you have to gear down.
Is it just me, or do you ride about 1km or more before it actually starts counting the distance??
