What is Tour de Giro?

Tour De Giro is an online, multiplayer bike racing simulation that uses your ANT+ powermeter, speed-cadence sensor, or CompuTrainer® to let you race and ride against real people in real time. Tour De Giro simulates head-to-head road racing: drafting, hills and teamwork all play the same effect in-game as they do in real-life. The 3D graphics engine faithfully renders real-world environments and all the competing riders to make your indoor rides more exciting and entertaining.


*ANT stick is not necessary

when using CompuTrainer®

“My Dad is in Auckland, NZ, I am in Taupo, NZ, so it is awesome to still be able to race him” "Scheduled my first race today had one other live rider and ten AI riders. Everything worked flawless. Your transitions from up hill to down hill to flats are great." “The software is brilliant. I like the graphics, smoother gradient transitions, results tracking on the website, AI riders make it more fun and interesting.”

"Great Thanks! I absolutely love your program!!! I am recovering from a broken clavicle and was looking for fun ways to try to stay in shape. - maybe even get in better biking shape since I can't run." "Man the feel of the change in incline is REALLY good in TDG…nice smooth and invisible-just as it should be! Very real feel! You guys rock!"
