With proper gear anyone could have done that ride in comfort... being a poor college kid I can't really afford spendy gear so at times it got a little cold.
My outfit was, long underwear, pants, wool socks, Alpinestars boots, bib type coveralls for the bottom half. On the top half I had a thin zip up sweatshirt, summer joe rocket mesh riding jacket with rain liner, cheapo winter gloves, and a wool scarf... the heated grips helped quite a bit.
The only times I was cold was Friday morning when it was sub 20's and the ride home Sunday when it was 30ish... but I was never cold to the point of really hating myself
I will say that I probably wouldn't go again without heated boot liners...
A pair of those and some of those hippo hands and I would hop on the bike and go back right now.
