From "
The Complete Guide to Climbing by Bike" by John Summerson:
'[It] starts out tame and ends up tough. The grade increases as you climb so that the average grade over the last 5.5 miles is 9%. The hill lets up just before the finish at Whitney Portal and the parking/hiking area.'Steepest section listed in the book is 11% between 8.5 and 9.5 miles, average grade is 7.7% after the first 5 miles of relatively flat area out of Lone Pine. And its considered one of the top 10 bicycles climbs in the USA; White Mountain Road, Onion Valley Road, and Horseshoe Meadows Road are also on the book's top 10 list. Hope you've got a solid 'granny-gear' in that truck!
