Small backpack for an overnighter?
A group of guys that I ride with are talking about doing a two day ride. We'd be staying in a hotel and eating at restaurants so no need for panniers. In short, all that's needed is a toothbrush, a change of socks, a new jersey (maybe?), a new pair of bibs (maybe?) shorts, a T, and flipflops. Total distance we're looking at is 150k the first day and maybe 150 ~ 160k the next day.
My question is, would I be ok doing a trip like this with a small/light backpack? I'm thinking of using a small camelbak that I have, minus the bladder. The group of guys are roadies, so we'd be riding road bikes. Riding in a pace line, etc. Some of the guys have one of those bags that hang from the top tube. One of the guys suggested NOT going with a backpack, as in the summer heat and riding hard, the backpack would be annoying. Not to mention a real sweaty back.
I have never done an over night like this before, so am looking for guidance/ideas/suggestions.
Thank you.
