Of the three challenges, the Everest is by far the most difficult but offers the best in-game reward. The California and Italy only require miles, the Everest only requires feet or meters of ascent.
I did the Italian Challenge and the reward was the Pinarello Dogma F8 which I was super excited about. It's my go to bike now of all the bikes in my collection, mostly because i wish I was riding one in real life! I know the Tron bike is the ultimate goal for most, but if you look online there are a few other bikes that are comparable or close to it in performance, weight, etc....
