I wouldn't ride right in Seville; although there are some wide boulevards and bike lanes, there's tons of traffic. Lot's of commuters, though, with Velo type rentals, like in Paris. But, I'm not a city type commuter.
Our tour drove us a little bit out of the city to start. We rode into the city of Granada (that was barely OK, it was Sunday), but I skipped the ride into Alahambra and took the van. Most of us did. The drivers were absolutely courteous, stayed behind long pacelines, gave us wide berths, and waved. But, the sheer number of cars were just something I'm not used to.
The temperatures in southern Spain in May were already brutal; if I had not lived in AZ and had some type of experience with those temps, it would have totally freaked me out. The first day we rode, it was flat, but totally unshaded. I found out my Terry Bella shorts are too heavy for 95 degrees. I ended up rinsing out my 2 pairs of Shebeest S Pros. It was about 65 in the AM, got up to close to 100 most of the days, until a front moved in and we had cool/cloudy weather for 2 days. Thankfully, the days we did the the climbs that were part of the Vuelta.
I loved Spain.
