I'll say my MPH for the 15 and 20 milers I am doing on rolling terrain and with minimal wind: consistently between 14 and 17 MPH. Sometimes I can keep up 18-21 MPH on a straightaway - usually only for a few miles.

When I ride by myself, I am always in a hurry and I like to be on a higher gear than I probably have to be. I do a good job of pushing myself - perhaps I do so too much. But I am kinda between groups - between people who are generally lovely but slow and people (ie men who cycle daily) who will drop me but are more my speed for probably 3/4 of the ride. I'm hoping that I can keep up in the future but I am embarrassed to hold the "race team" back. There are a few women who ride those rides, but they come less consistently and it kinda bothers me because it's not fair that I should keep up with those very accomplished guys!

I hear you. I have been riding really seriously for a year and a half and in that year and a half, I have had to stop riding many times because I was hospitalized, had surgeries,etc.

I wish I could find a good riding partner! Blargh.

I don't think my MPH's are to be scoffed at, but they are not out of this world! My goal is to be a better rider and keep trying.
