We've thought of that - but the Creel date is pretty carefully selected to avoid the HOT summer and RAINY seasons. August through September in Creel is not good bike weather.
Canada meeting date is picked to avoid the summer crowds on the highways in Canada.
Don't forget there is now the option of doing the Colorado Meeting then heading for TDF - should be plenty of time, especially if you go straight down through Chile - and then back up, slowly meandering your way along.
There is no perfect date...
Seek, and ye shall find.
