Catrin, try using a saline nasal spray before and even while you are riding for the rhinitis. My doctor suggested it at the beginning of the summer and it has really helped. I bring it with me on long rides.
I used to wear knee warmers or knickers up to 70 degrees, but now I can go as low as 60 or so, if the sun is out. But, I like my knees covered. I have so many thicknesses of wool socks, one of them is usually right for anything below 70, too. The gloves, though, I do short fingered down to the low fifties, as my hands seem to sweat a lot!
