Now that the 2011 Tour de France is wrapped up, let’s take a look at how some of we more average cyclists would fare against the sports’ heros. Our friends at Bicycling Magazine compiled this list of stats comparing an average cycling enthusiast and a professional Tour racer. These estimated numbers are staggering to say the least. —T.C.

Power and Speed
> Average speed on flat terrain: 17–18 mph (you); 25–28 mph (pro rider)
> Average speed on mountainous terrain: 9–10 mph (you); 21–25 mph (pro)
> Estimated average watts at threshold: 170–220 (you); 405–450 (pro)
> Miles ridden in a week: 75–140 (you); 700–800 (pro)
The takeaway: TV coverage doesn’t show the real story. It’s staggering to witness how fast pro cyclists go uphill in person. Their strength-to-weight ratios make these speeds possible. For wattage, it gets crazier still: Depending on his size, a sprinter like Garmin-Cervelo’s Tyler Farrar can produce more than 1,400 watts of power heading to the finish line!

Food/water
> Calories consumed on a ride: 200–450 (you); 4,000–5,000 (pro)
> Bottles of water consumed (three-hour ride): 2–3 (you); 4–20 (pro)
For the calories, it’s not unheard of for a Tour rider to burn up to 8,000 calories during a single stage! Water bottles: Depending on the stage distance, temperature, and terrain, the numbers fluctuate from 1 to 4 bottles an hour for Tour riders.

Bike and Gear
> Cost of a race bike: $2,000–$7,000 (you); $9,000–$14,000+ (pro)
