You're all very seasoned bikers and I am not, but I do ride as much as I can and lately have been doing a lot of spinning - even two hours at a time. I generally ride for about 2 1/2 hours outside, but that's about it. I'm retired so am not a youngun' but you all motivated me and I signed up for the Wine Country 100K in April. Here's where I need some advice. I only have a hybrid (wider wheels) but am keeping my eyes peeled for a used road bike. However, if I can't find one before the ride, do you think I could ride my hybrid? I suppose it would take me longer, but would still appreciate your thoughts about this. Thank you.
