We've modeled the Out and Back Again route using the typical standard bike characteristics from Zwift along with rolling resistance data supplied by (Zwift Insider ). For the rider, we modeled a lighter athlete holding roughly 2.5 to 2.7 Watts/Kg.
Use the Time Analysis Tool to adjust Drag (CdA), Average Power, Rider Weight and Rolling Resistance (Crr) to your own specific numbers. For detailed information on specific sections of the route, simply drag over that section on the Time Analysis chart to zoom in (note the data under Route Overview updates to Zoomed Area).

Zwift courses do not use real world weather data, but with a real world race and a Premium Subscription you would see data on temperature, humidity, pressure, wind speed and wind direction for the entire course.
