It's not quite a metaphor! The expression "have a long day" means that the day felt like it was a really long, tiring day. Sometimes it implies something negative. You can use it when you've had a long, tiring, or tough day. Here he's emphasizing that it was a lot of work and tiring, but it was still good. Ex: I've had a really long week, so I just want to sleep this weekend. Ex: It was a long day, but it was good.
