97.9K pages indexed. Is this too much?

I made a website that gathers the main contests and hackathons of different categories to ease the process of finding them. I thought positioning my site for keywords like "\[category\] contests & hackathons in \[city\]" would be a great idea. However there are lots of categories and cities so the combination of both resulted in thousands of pages being generated. Is this a good idea or will it have unexpected results?
