MIMS finishing times: 1982-2010

MIMS finishing times: 1982-2010

Five months until MIMS! In the meantime, some data porn for your enjoyment (click to enlarge):

The NYC Swim website has MIMS results as far back as 1915, but the modern version of MIMS as an annual marathon swim race began in 1982, when Drury Gallagher founded the Manhattan Island Swimming Association.

The chart above shows every MIMS finishing time from 1982-2010 (black dots), along with the slowest, fastest, and median time of each year (blue, green, & red lines, respectively). Only participants in the annual MIMS race are shown – no solo attempts (e.g., Shelley Taylor-Smith’s record swim of 5:45 in 1995).

    Big Shoulders Stats: Finishing times

    Big Shoulders Stats: Finishing times

    People say times don’t matter in open water – or at least that you don’t always know what they mean. And perhaps that’s part of its attraction. While in the pool “the clock never lies,” in open water it’s not much more than a ranking device.

    Even so, I’ve been surprised by how closely most of my open-water pace times have approximated my pool speed at various distances – from 1:15 at 1 mile (Huntersville), to 1:17 at 1.5 miles (Livermore), to 1:19 at 2 miles (H’ville again) up to 6K (Windsor), and 1:22 at 10K (Noblesville).

    When an event has been staged for many years, though – at the same location, on the same course layout – comparing times makes a little more sense. Big Shoulders is one such event.

    In that spirit, here are the finish times in Big Shoulders across the 12 years of available data, starting with the 5K race:

    5K times

    That chart is a little busy, so let’s unpack it:

    • Each black dot represents one swim. The dots are “jiggered” slightly to the left or right of their corresponding year (so more of them are visible).

    Big Shoulders Stats: A local race?

    Big Shoulders Stats: A local race?

    More Big Shoulders stats, from my custom-made aggregate file. Here’s the proportion of Big Shoulders participants hailing from Illinois, Indiana, and “other” – i.e., anyplace besides IL and IN.

    Clearly, Illinois locals still predominate, but recent years have seen a greater influx of out-of-state swimmers. In 2009, almost 30% came from outside of Illinois and Indiana – an all-time high.…

    Big Shoulders Stats: Participation by Age

    Big Shoulders Stats: Participation by Age

    More fun with Big Shoulders stats. We’ve been looking at participation – so what about age? Masters swimming is traditionally dominated by people in their 40’s and 50’s – is the same true here?

    It seems the modal age is actually a bit younger in Big Shoulders – lots of people in their 30’s. But the “50’s” have been mounting a furious comeback (see the blue line) – perhaps a baby boomer effect.

    My custom aggregate CSV file, from which I calculated these stats, is available here.…

    Pan Pacs: The story of the splits

    Pan Pacs: The story of the splits

    Splits tell the story of a race. It’s perhaps even truer in open-water swimming than in the pool, because the races are more “spread out” over space and time. Splits are rarely kept for O.W. races, though, due to obvious logistical obstacles.

    Powerhouse Timing has been working to change this – at least at the elite level. At this past weekend’s Pan Pacific 10K Championship, they captured splits at each 2K for the entire field, both men and women. And what an interesting story they tell. Here are the 2K splits, which I converted to pace-per-100m:
