That's a really common question, but its not really about average speeds.... its more about your ability ride in a pack, to deal with surges and to recover. Some people who TT quite well don't do that well in pack races and can even fall off, because its a different kind of effort.

The best way to find out..... try it. That said - have at the minimum some group/ pack riding experience before you go out and jump into a race.... Be confident in your handling skills and know how to paceline. Even better, take some intro to racing classes if you can find them in your area, look for training races or workshops and best of all - join a team with other women.
