Can Pages tally individual user items?

[Square Wheels]

I run a cycling site, a user presented the following:

The idea is that we start a topic where people enter their daily miles (cycling only, I think, or it will get messy) and we add them to our forum total as we go.  We start on Jan 1 and we try to get everyone to participate.  So if I ride 20 miles, I post it in the topic, "20 miles on 1/1/21.  20 total."  Then the next poster enters, "26 miles 1/1/21.  46 total."  And so on.  People wouldn't have to post each day.  If they miss entering their rides, they could then post multiple rides in one post and total them, as long as they don't replicate previous dates. We can set a forum goal, depending on how many participate of, say, 50,000 miles (twice around the earth) or even as much as 112,000 (half way to the moon).  Whatever seems doable. 

I have Pages, is this something I can create a page where people add their miles and a date and it then lists that user, their miles, the date, and a total among all users?

I have never built anything with Pages.

Thanks

You can do the first parts out of the box easily: an input form where people enter their miles and date. You would then need custom coding to show a summary for each user and a total.
