Tricky? No. You'll be warmed up by Questa. After that it's rollies to the bridge over the Rio Grande, a stiff but fun climb out of Taos, a nice pedal to Bobcat Pass, and a bit of a stiff uphill before you coast back into Red River. After about 5 1/2 to 6 hours of great riding you're drinking beer and eating Bar-B-Q! This is a not-to-be-missed Century.
