A big NO for me. This is the fifth day I haven't ridden since the beginning of April. I went out rollerblading with my wife and oldest kid. My third time out. (Can you guess what's coming?) All I can say is that brakes suck on roller blades and I don't see myself rollerblading on any more hills until I get a lot more comfortable on them. If the saying about you're not bleeding until it hits your socks still applies, I guess it wasn't too bad. Still, my wife wants to go out on a tandem ride this evening and I'm not sure if I'll be up to it.
