"Matt Damon" isn't in the results but he is wearing a bib in picture 4 of the article. And the article says he ran and was waiting for his gf to finish so he had to be done in under 2:30ish.
In one of the pictures from the article, it looks like it could be 146 or 148 or something else, but is partially covered by his medal. Both are registered. 146 is a male of similar age (44 vs 45), while 148 is a female in the results.
Anyone able to figure out his time? Maybe another picture of him with a clear bib number floating around out there...
