Will be tackling the Pyrenees at some point, followed by Sardinia, Italy, Hungary, Croatia, along to coast past Greece to Turkey is the planned route.
It is my first tour and I am feeling a mix of anxiousness and excitement! Even right now.
Sounds like it could get quite hot later on in the tour. I have similar concerns, I'm hoping to leave San Antonio TX second week of June and ride to New York State (about 2,000 miles). Assuming I can stay on schedule, the first two weeks out of Texas and northeast across Arkansas might be tough until I can accumulate some latititude and literally leave the sun behind to some degree (we're at 29 degrees north here in San Antonio, in June the sun is only about seven degree off of vertical at noontime).
