I find I really have on and off years, sometimes not by choice. For example, this year I had to have hip surgery so I will be lucky to get 2500 miles in (I haven't looked, but that's my estimate). On a good year, I'll get 4 - 5000/year in.

1. What kind of bicycle(s) do you ride?

99% road. I have a MTB but it is just a vacation thing right now.

2. Do you do anything except ride during the riding season? (work, clean house, cook, take care of parents, etc.)

I am a lawyer and run my own business, have a high school daughter and have 2 large dogs that require walking. My husband also is a cyclist. The house is moderately clean but I tend to get VERY behind on folding laundry.

3. Do you ride in bad weather? What kind of weather will you not ride in? (i.e., severe downpour, high winds, temperate, etc.)

Yes, especially if it is a ride I have planned to do. If I'm just going out for an "off" ride, it's harder to motivate to go out if it is absolutely pouring at the start of the ride.

4. Do you have apparel to ride in all kinds of weather?

Oh you bet. It's pretty mild here all things considered, but we can get torrential rain and I've ridden over 3 hours at a time below freezing.

5. Do you ride at night?

Yes, especially on long brevets and double centuries. I've ridden through the night, and I've done that alone in the past (riding til 2 am alone for example), but I now refuse to ride alone at night (if at all possible).

6. Do you use clipless pedals? Does anyone only use plain pedals?

Yup Look Keos.

7. How many mph do you average? If I average between 11 mph and 12 mph do I have any hope of ever achieving a goal of 1000+ during a riding season?

I agree with Eden that this is pretty irrelevant - it's also completely dependent on where you live (terrain wise). My MPH for rides totally depends on the length of the ride, terrain, wind and how I am feeling. Looking at my Strava, I'm anywhere between 12 - 17 mph. I absolutely think you can ride 1000 miles a year if you maintain 11 - 12.

8. Do you ride mostly on trails or on roads?

Roads.

9. Are the trails/roads or flat, hilly, steep hilly, or mixture?

Hilly, steep and mixed.

10. Do you do most of your riding alone, with someone else, or in groups?

Both.
