Time to get moving, power

February 7, and I don't have the fear I had last year. This might have something to do with not having signed up for the triple. I *do* have plans for the Santa Fe Century in early May though.  3 months away.

I sat on the seated squat and ran 50lbs for 2 feet  once per second. The inside first page of my old physics book says that 1hp is 746 watts and 550 ft-lb/sec. I was getting something like 100 ft-lb/sec or about 135 watts.   ....but for only 6 minutes.

A post from last year says we did 2600 feet in 1.5 hours. At a 5% grade (average), that's 10 miles. A bike calculator says that puts me at about 150 watts or 1/5 hp... for 90 minutes!

The same calculator puts the 120 miles and 10,000 feet of the triple, if I drop my weight down to 165, at 175 watts over 15 hours!

For comparison, if Neal weighs 140, he only needs 153 watts. Either ride is 8000 or 9000 calories before considering the efficiency of the body. The ride is so much more than you think, the weight difference is nothing compared to how fit I am now compared to how fit you have to be.

Losing the 15 pounds from 180 down to 165 is worth about 14 watts, the difference between 189 and 175: a gain of 40 vs 55. That's almost HALF AGAIN what I'd need to gain.

BTW, the Santa Fe century is nothing to sneeze at: 100 miles, 6000 feet
My performance on the triple last year was almost 60 miles in 5.5hours of riding and maybe 6000 feet of climb. The calculator puts that at close to 175 watts?
