Route Description
This simple route begins near the Harbor and proceeds in a clockwise direction along the canal to the Tower Sprint. Then we turn right, riding under the overpass and past the neon trucks, making our way down to the Alley Sprint Reverse before finishing off our lap at the same virtual banner where we began.


It seems like a short one, maybe .1 or .2km? I guess not that it really matters, being so short, but I was surprised to see it on the ride summary when I started. This and Castle to Castle aren’t in the printable toughness list yet. This one was a nice quick ride, with two gates. Just short enough for me to PR them. Thanks for your work trying to keep up on all the Zwift stuff. Ride on!
@eric, it says above no Sprint segments, but there are 2 sprint segments in the route. Just FYI for the error. Came here looking for the length of the sprint segments.
Huh. That’s odd. Wonder how we missed that? Anyway, just added them.
