I don't know why 'short' rides would be bad for a bike. There are weekends I end up spending hours and hours on the bike but most of my riding is commuting to and from work which is only 15-20 min each way and it's great for that. I can't imagine a ride being much shorter than that. If I was only using it to travel 5 min down the road I probably wouldn't have even bothered getting the bike.
As far as break in just follow what the owners manual says, take care of the first service, and enjoy riding.
