Call me weird. I wear pads. Never had a problem when on my cycle. I use thin pads and keep an extra in my bag.

Ironically I got my period while on the aids ride, completly off cycle as did a lot of women on the ride. Luckily I had supplies with me.

I'm lucky I guess, riding actually relieves my pain and discomfort.

Find what works for you.

I wish you luck.
