She should not be experiencing those sorts of problems at all. That part of the anatomy should not be coming in contact with the saddle, or only just barely!!

1. Get her a proper saddle ... a Brooks! That way her sit bones, NOT the middle parts, will sit on the saddle.

2. Get her set up on the bicycle correctly. Again, she should be sitting on her sitbones. And the saddle should be low enough so she is not rocking from side to side to reach the pedals, and the saddle should be high enough so that she is putting extra pressure in the sitting area.

3. Make sure she has good cycling shorts (no underwear, of course), and the padding on those shorts should cover her sitbones without being too thick and heavy up front.

If the bicycle is set up properly, she has the right saddle, and she is wearing good, comfortable shorts, she should be able to ride well over 100 miles at a go without any difficulties.

4. But if all else fails ... and after a hundred or more miles in the saddle she is experiencing some difficulties ... Ozonol.
