I am signed up to ride the Reston Metric Century tomorrow and it looks extremely likely it is going to rain. Initial forecast were calling for 40% chance of rain later in the day, but now it looks more like 80% chance and the rain is likely to start before we even start the ride. (I was hoping to start by 7am.)

I thought I would get other people's advice on riding in the rain. I have never trained in the rain, I have never even been on my bike out in the rain, so I am definitely worried. I really want to ride tomorrow though, I have been looking forward to this for a while. I am planning on a full century next month, but this one was part of my training plan.

Does anyone that has rode a century in the rain have any tips/suggestions? Would you do the ride regardless of the rain? Weather reports are calling for scatted Thunderstorms too.

I also don't have any rain gear. Do I need to worry about the rain and how it might affect my bike?

Thanks for any replies....
