Runners often get identified by their finish times, a sub 3 hour runner and so on. Runners like this distinction and wear it with pride. Here is a chart of how runners finished under different time thresholds. We put them under 4 time categories; sub 3 hour, 4 hour, 5 hour, and 6 hour. These numbers are an indication of how competitive the field is for a given year.

• By far the year 2019 was most competitive. There were 87 runners finished under 4 hour mark, which is an amateur runners dream.
• There is sudden dip in 2018 in sub 5 & 6 hour finishes. What could be the reason? Is it the weather or something else?
