This puzzle is about an athletic, hearty person. Therefore, there are 3 pieces of information hidden accordingly:
For each clue, including trailing remarks such as "(2 words)", remove all numbers, spaces and punctuation. Color in the grid the cells with letters in the corresponding answers that match the letter(s) at the heart of the clue. The result will be a set of symbols that represent something that person is associated with.
If you're observant, you might notice one symbol was missing. Look for a straightened version of it near the heart of the crossword to get another adjective that could be used to describe this person.
If you want to see who the person is, you can obtain some useful information by reading the first letters of every clue for which at least one letter was marked. A few clues near the heart of the crossword should help disambiguate some details.
Come back here with the three pieces and the identity of the person for your green tick!
- If you need to read something off of the grid, it will be in reading order (rows from left to right, then columns from top to bottom). That goes for all 3 bullet points.
- Someone is probably going to make one anyway, so if it helps here's a spreadsheet with the grid. Please let me know if you find any inaccuracies and I'll correct them.
Erratum: For 130-across, only the cell corresponding to the second letter should be colored.
