I'm planning to do the Transamerica (E-W) and Sierra Cascades (N-S) in the summer of 2012. I will arrive in Washington Dulles Airport and pick up the Transamerica Trail somewhere south of. Thus, I will not backtrack to Yorktown. The thing is I am riding fast: On average I do 125 mi a day with no rest days at all. This is my riding style and I am happy with it. Thus, the entire trip will be approx 6300 mi/50 days.
I would like to avoid too much heat in the East and as a result start somewhere around late may. However, already 2200 mi/18 days later I should be in Pueblo, the beginnig of the Rockies I believe. That should be mid-june. 1100 mi/9 days later (end of June) I should arrive in Missoula. That should be end-june/start-july. In between I have the Hoosier Pass.
Can anyone comment on the weather conditions in the Rockies in June? Should I leave Washington DC 1 month later and accept more heat in the East?
I see that going E-W is perfect when riding at a slow pace
Thanks in advance,
