Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Cool OLD article on Landis' power output from 2005

This was the year before he won the Tour.

https://www.wired.com/news/technology/1,68310-0.html

Apparently he averaged 232 watts for the total time on the bike (amounting to 70,914 kilojoules of work) but was at 500+ watts for 4 total hours and averaged 379 for 75 min in the time trial.

Anyone know what 70,914 kilojoules would power in a household? What if split over 21 days?

Cool.

On his way to a ninth-place finish, Landis spent nearly four hours of the Tour at a power output level of more than 500 watts -- that's a flat-out sprint to most recreational riders,
I couldn't touch 500 even if I have cocaine-filled syringes stuck to my veins.

Google knows all:

70 914 kilojoules = 19.6983333 kilowatt hours.

I think I'd have to sprint to even think about 500W. Yikes!

that would power the average household in the US for about a day.

Sadly, not quite. Fromt the online data I found (and yes, it's online data so who knows) they all seemed to claim any where from 8,900 to 9,500 KWH per year for the avg. american house. So that's 24 kwh a day. Still, pretty incredible. And if you think of it in actual time spent on the bike, Landis put in about 97 hours, so that's about 4 days of work for about 1 day of energy.
