No, just a typical nervous new rider.

Before going, familiarize yourself with the area and if possible get the route. If it's a reasonable size group someone should be posting their rides on Strava and you should be able to figure out the area they ride in. Once you're familiar with the area, you won't need to worry about getting dropped. Consider the ride as an adventure for a morning. If you stay with the group, great. If not, you get a solo ride in a new area.

Zero risk, just try it.
