You're right - when I put it on a calendar it is completely reasonable. My long Saturday riding distances are all at like, 25/35 for this month (although I usually do more since I ride with a club...) and my long runs don't gear up past 5 miles until after August. By then I should be acclimated pretty well.

I am also going away for a week in August but will hike and run while I'm away... won't be doing any biking. No biggie.
