As a client, I would like to see the breakout for how my points are tallied instead of just seeing my total.

I think this could easily and cleanly be provided with a 3rd icon on the bottom challenges view and would show a table of the challenge items, points per, my # of events in that category, and then that line item subtotal. And then at the bottom, or top, would the cumulative total.

and for the coach it would be something like a spreadsheet;
the vertical row would be each participant's name and horizontally would be a column breakdown of each challenge item and its worth
