Hi Colin,
Your plan sounds interesting to me. I'll be in town those dates, and the objectives align well with my interests.
I did the DC route in August and was in training to attempt Denali this month. Had to travel to China several times this winter and move to Seattle this month for work. All of this put my Denali plans on hold. I'll be doing 5 volcanoes this summer as a consolation prize, and it would be great to repeat the DC at a more efficient pace.
Here is my data for summit via DC on Aug 2015. It was guided, slow-moving, all within my Z1 HR. It was enjoyable, but not the challenge I was looking for.
