Hi Taysel, welcome to TE! Please drop by the Getting to know you thread in Open topic.

You may also want to visit the Favorite / Least favorite saddle threads (see main page of the forum).

It takes a while to get used to sitting on a bike, and if it was your first 30-miler and you didn't do that much before, it's not abnormal to feel sore, but it should go away within a day or two.

You do not specify what sort of bike you have but in almost any case you may want to try this trick that my friend discovered when she first rode with me. On her first ride she really felt sore as you did, and at some point during the second ride she had an epiphany: she discovered that by slightly tilting her hips she was in a much more comfortable position. Basically, I think it's about sitting on your sit bones. Experience with different positions, add distance progressively, and you may find something that works. Of course it can also be the saddle. Or the tilt of the saddle, which is often adjustable (can be neutral, forward or backward).

Also, you don't specify if you have used bike shorts. I would STRONGLY encourage you to get a good pair of shorts and to wear them without underwear. That will make a world of difference. Browse the Apparel threads for more details.

Enjoy the ride! Welcome again.
