Not sure what a long ride is...being out for 4-6 hrs. on the bike?

Where we are now the temp. begin in morning from around 40 degrees F or below and go up to 80-82 degrees F. by early afternoon. So how I dress would be long shorts (but long, thin tights go well with me also) or wind pants if it rains. A light fleecy jacket, a light gortext vest (which I remove the fleecy if I get too warm) and light cycling light over top. Carry a rain jacket in my bag.

I would not need toe covers. Yup, long light full gloves, then switch to half fingered later. Headband for first 2-3 hrs.

Given your temp. at peak, I would wear long sleeved jersey. But right now I am wearing short sleeved jersey underneath.

Everyone is different. I know by early fall --what I wear at same temp. is lighter compared to early spring at same temp...it's because my body has hardened as cycling season moves through spring, summer to fall.
