Suggestions for user workout logs

I’m looking for some ideas/suggestions for solutions for my client’s site that I built in WordPress last year. It is a university fitness program and they are looking for a way to extend the site for users of their program.

They would like a message board/forum for their marathon training program, and I know there are quite a few plugins that would allow me to do this. The other thing they’d like to do though, is provide a place for users to log into their account and log their workouts. So – what I am looking for is a way for logged in users to enter data into some kind of form and then be able to view this data, view a list of entries, etc. It would be fairly basic data – workout time, pace, notes. I’m just not sure of a way to do achieve this in the front end, for WordPress users (not admins using the Dashboard). Anything out there that might work?
