Also, what's your summer riding been? The middle of every other day, mid-day once a week, or once a month? After I've got a base tan (from weekend rides), I don't usually have to worry about sunscreen on my thighs.
I've experienced something similar and to a lesser degree around my ankles after 3 or more hours exposure to the sun. Doesn't really feel dry and scratching like my imagination thinks a rash should. My doctor (when I was in for annual) suggested it might be capillaries in the skin enlarging towards surface to protect the skin from the exposure...new to me.
I try to ride three times a week, goal is 100mi, norm +70. I usually ride AM starting btwn 9 and 10. I've got more base tan than I've ever had, but I am still fair complexion. The issue shows up on bike rides of 50 mi or more where I'm in the sun a good portion of the peak. I think a new sunscreen is probably the minimum I'm looking at for long rides.
