The question was posed in an earlier thread....are runners more likely to run their fastest time at Mt Washington the first time they run it or do they tend to PR after getting that first one under their belt. I checked the stats for the 188 guys who have broken 1:10. Of course none of this takes into account weather (a major factor). Here is what I came up with:
72 only ran it that one time
81 did not run their best time the first time
35 set their PR on the first attempt
I'm not sure if this really tells us anything......
