Are you bored with the gun, or bored with standing at the line shooting static paper targets? I would suspect the latter. If you haven't, take a basic defensive pistol class. You'll shoot a bunch, but more importantly, you'll get some drills that can make range time more fun and far more productive. You can really get most of the drills from YouTube.
Englishbob,
This is great advice above. If you could answer some questions, I'd appreciate it.
1)where do you shoot?
2) what do you shoot at?
3) have you ever shot an IDPA or other practical shooting event?
4) if no - have you ever considered shooting an IDPa type event.
5) so I can make suggestions on places to go, where do you live?
With that said, ifyou shoot the 226 well then you should keep it. Especially if you don't have any other guns to use as a point of reference. My suggestion to you is that you buy something like a Glock 17 or 34 or an M&P 9 or similar gun. They are just as good as the 226 but very very different.
You may find that you prefer the 226, you may find you like them both equally well, you may also find that you like the Glock/M&P better.
I don't like traditional double action guns like your 226. Because of that I shoot mainly Glocks and 1911s. But thats me. The 226 is a fine firearm. One of the best.
I hope this helps.

p.s. Whichever one you choose, I'd strongly suggest that you pick up a .22 conversion kit for the .226 or Glock. Other than the last two years, .22 has historically cost about 1/8th what quality 9mm costs. It will eventually get down there again. Having a .22 conversion allows you to pull the trigger on a gun you know 8x as many times for the same cost. If I'm practicing for a match with my Glock or 1911 I may practice drawing and firing the first shot 100 times with the .22 kit on it. (when you are only firing 1 shot the recoil difference is irrelevant) Eventually I switch to 9mm or .45 and finish up.
p.p.s. You should NOT EVER feel like "I'm not good enough to compete". Everyone was new at some point. As long as you check your ego at the door, people will bend over BACKWARDS to help you out. Unless you are a pro competing for money, its much more fun to watch other shooters do well. And even then, I've seen pros giving suggestions non-pros at high profile events.
