do i need new tires?

ok sorry, total noob. here are some pics of the tires. i am going to do triathlons. also, the sizes are 700x20 and i wonder if that is a little narrow, maybe go with 700x23 which seems to be somewhat common?

thanks for your help, sorry if this is obvious.

I think the tires look ok.

When you replace them, get some 23mm wide tires. They won't add any additional rolling resistance, and they'll give you a more comfortable ride than the 20s .
