Is there a cycling club in your area? Sometimes they will rate their rides and have shorter, easier rides for new people. You may meet people who you can ride with outside of the club.

I personally love to ride alone. Gives me time to think, reflect and generally just rest my brain. Something about the rhythm of the pedals lulls the worrying part of my brain to sleep. I've never really thought about being abducted & I've been riding over 20 years (even before cell phones & when women had to buy men's shoes & shorts ). I suppose if somebody tried to grab me, it would be like the Ransom of Red Chief - they'd be trying to return me & nobody would take me.
