As unpleasant as it sounds, using a catheter during our Baja 1000 race wasn't a big deal. My wife did a test run at home to get the hang of installation and to insure that it sealed correctly. Although not as easy to use as the men's version, it wasn't all that bad. She used the glue and tape and was very satisfied with the catheters performance.
This is one of the only products on the market geared towards the racing female. I would suggest a test run at home prior to using it for the first time in the race car. Placement is key when applying the device. You may want to use a back up diaper the first race use. My co-drivers loved it when they got into a dry seat in Mexico.
Being in a long race the last thing you want to think about is sitting hours in fluid. Kitty Kath let us have the ability to go anywhere and in the race and is the only thing On the market that can do so! I recommend using both the glue and tape for extra Saftey on fitted to!
