I need to figure out if I can do a century without purchasing a new pair of bike shorts. I just got a new pair , and the padding is fairly minimal, but ok. Also, the fabric of the shorts is not very tight against my skin. It feels good on me, like a layer of silk actually, but there's no compression. Should there be? Will I need that kind of support? I can finish a century, but I will be sore and tired, and probably come in dead last! Are there recommendations for bike shorts?
