My friend kept up with me for 30 miles on one of his first rides on his Kilo TT. Before that, he never really rode much.
5 miles in temps reaching 100 where I am is certainly something. I usually wear work clothes i.e. jeans but lately I'm wearing lightweight nylon hiking shorts and under armor type moisture wicking shirt and then changing when I get to work.
