And you thought Ink Grade was painful??

Fifteenth toughest ride in Napa. In Napa, that too!

15) INK GRADE 247 ft/mi. Total distance from Pope Valley Rd. to White Cottage is 4.5 miles and 1110 feet of climbing. Very nice ride with plenty of shade, lots of breaks especially at the start. One of the longer climbs in Napa but not as difficult as most. Also part of our righteous Tour of the Napa Valley.

247ft/mi?? chhii.. not even 5% grade.

how about this for a climb?

2) SPRING MTN (starting from St Helena) 526 ft/mi. I rank this second even though there are two other climbs that are steeper, but this one is longer and there are essentially no breaks. Total distance (from Y in the road to county line) is 4.5 miles and total elevation gain is 1560 feet. The major pitch however is 1.9 miles long and 1000 ft with virtually no breaks. It is covered in shade which helps but I've only attempted this twice in 7 years just to give you an idea of how much I enjoy this one.
