Should I take the official Parkrun time or my own?

Oxford Parkrun again today. Quite pleased with the run, though I'm looking to get faster. At the finish, my Garmin said I hadn't quite done 5K, so I grabbed my finish token and ran on a short way until it registered the 5K. My time per Garmin was 30:08. When my official time came through, they'd clocked me at 29:54.

My conscience says I havent yet run under 30 minutes at a Parkrun. What would you do?

  • I would say go with parkrun , thought the courses were measured and confirmed 5K's ?

  • Yes, though it depends on the marshals setting up at the right point. For my first couple of Parkruns here, they started the run 100m from the right point!

  • Hmmm not to helpful then

  • Definitely go with the official parkrun - if that's what they clocked you at.

  • Realistically speaking, if you can run 30.08, you can run 29.54 so I'd accept the official time - it's not like they've clocked you at 18 minutes or anything. Well done!

  • Thanks :) I have actually run 29:49 over one of my own courses, so I know I'm just about there.

  • I always take whichever is faster for my races. Chip time or Garmin, either could be off for various reasons. So I err on the side of happy speediness.

  • It's your run... Take the best time!

  • I'd say you have...well done :0

  • Thank you, everyone!

  • I always use my parkrun time as my "official" 5k time, even though I have clocked a good 20 secs off using other tracking. I use Runkeeper on my phone and my GPS watch for nearly every run and they very rarely give exactly the same results and sometimes vary quite considerably, even though both have appeared to give a good solid track. If you run the same parkrun, then that will give you an idea of your progress over time, so long as they start and finish at the same spot.

  • I guess it's true that as long as you can see that the Parkrun is consistent in start and finish lines, it's a pretty reliable indication of progress. It's a bit frustrating that you can't have 100% confidence in what one's GPS watch tells you!

  • A definite sub-30 minute run. You will also have stopped the watch after your finish thereby losing (valuable) seconds. Go with what the Parkrun team say.

  • I have that trouble with my parkruns - for the last few my Garmin hasn't had me anywhere near 5K at the end.

    But if I look at the track of the run on Garmin Connect it shows corners being cut and sometimes randomness when under trees. So I think its a fault (maybe foible would be better) of the technology.

    My Garmin (Forerunner 220 and most of the mid-low end ones) only record gps readings every 4-7 seconds, in which time you could have gone round a bend which the Garmin will miss so "straight-line" you to the next point it records.

    I go with the "the parkrun course has been measured, and is damn near the same every week so that'll do me" school of thought.

  • Interesting point!

  • Have a look at the Garmin Connect tracks for your last few parkruns and see if they show any obvious deviations.
