Multiple users can log results. Does a plugin like this exist?

I’m hosting a virtual marathon, and the gyst is that you run 26.2 miles over the course of a month. At the end of the 26.2 miles, you get your medal/shirt. It’s all on the honor system.

I’m wondering if I could use WordPress to power this… allow each user to have their own page where they could log their miles.

Maybe it’s not the best use for WordPress and I should look elsewhere, but I thought this would be a good place to start.

Thanks!
