A couple of weeks ago I found myself in a paceline ride.  I wasn't aware it would be this type of ride until I was into it.  I spoke with the ride leader who advised me to sit at the back of the ride and not take a turn pulling.  I've since read about the mechanics and watched some youtube videos on paceline riding.  Should I wait until I can take the SBRA's training class in paceline riding before joining one, or am I overthinking this?

Thanks
