Alta Alpina 8-Pass Challenge Double Century, 20,300' Ascent

June 30. The Alta Alpina 8-Pass Challenge will be my 4th double century this year (plus the Sequoia Century 200K). I am ready for it.

The Alta Alpina 8-Pass Challenge is the toughest double century I know of, even more climbing than the 18,800' Devil Mountain Double:

• 20,300' feet of climbing.
• 198 miles.
• Altitude up to ~10,000'.
• Half of the course above 7000 feet of elevation.
• Can be very HOT and VERY COLD the same day.
