Well according to that sheet, about 34% of participants qualified, so I'm not sure what the criteria was in the end.
However if you want to know how close you came to qualifying / not qualifying (delete as applicable), here's the slowest time that qualified in each age category as far as I can see it - assuming I exported it to Excel correctly of course!
19-34 Male - 03:55:46
35-39 Male - 03:58:38
40-44 Male - 04:00:42
45-49 Male - 04:04:11
50-54 Male - 04:09:23
55-59 Male - 04:13:57
60-64 Male - 04:27:39
