I like this work. Yes, it has severe limitations and the authors make ridiculous claims. Yet, the idea is fairly sound within the context of the target problems. (more…)

Yesterday (11/04), I rode up to Ward. Started from my office around 11:45AM and reached there around 2:15pm. The climb was uneventful (well, for the second time I managed to reach there without a break!), although cold. By the time I reached there, my fingers were numb. It was so nice to hold a warm cup of coffee in my hands and to feel it becoming alive again:)

But the return journey was miserable. Although I was wearing three layers, I was cold.  I was shaking uncontrollably  and at times I could not keep the bike steady. In fact, I had to stop after every mile, sometimes even before that. It was the longest  downhill in my life. Took me more than an hour and a quarter to go down the 17 miles!  I still don’t understand why I felt so cold. Yes, the numbers weren’t bad: 52 miles and 4000+ feet of climbing. But statistics don’t tell everything.

To compensate for yesterday’s misery, I went out today and rode 50miles of rolling hills and flats. Home-Dillon-McCaslin-75th-Lookout-79th-Niwot Rd-95th. 95th-Oxford-CR119-CO119-WCR1-Rinn Rd-WCR7-CR8-US287-Baseline-95th. Just to make sure that I have a real half-century and not an approximate one, I detoured into Louisville. In the end, the numbers were 50.48miles in 3 hours and 23 minutes.
