THANK YOU so much to all the runners, walkers and especially the volunteers that made this years Run A Muk so successful! It was a bit wetter than planned but you guys rolled with it and made it not only happen but lots of fun but made it lots of fun too! 🙂
The weather did create a few glitches which I'll make sure we are prepared for next year. Promise! Unfortunately not only did my microphone fall victim to the damp, the timing system hiccuped it's way through as well. That's exactly why we have not one, but two, backup systems in place!
Everyone that was assigned to and ran in Wave 1 has an accurate chip time.  There are a couple of chip times that make me wonder if someone signed up for one distance but ran the other.  (5k to 10k or 10k to 5k).  If that sounds like you please drop me a note with the distance you ran so I can correct the results.
Wave 2 and Wave 3 chips did not fully register in the timing system.  For these waves I went with a combination of what registered in the computer, the time stamped camera photos at the finish line and the manual record with times that our timing assistant wrote down.  I also assumed that EVERYONE in these two waves not only started in the appropriate wave but ran the distance they signed up for.  Again there are a couple of times that make me think that some switching between distances and maybe even waves occurred.  If that sounds like you please drop me a note with your details so we can correct the results.
And lastly, you'll see a handful of folks with no times.  There were a few folks that had their bib number covered as they finished so neither the camera nor the timing assistant caught their times.  If you are in that list and have a record of your time yesterday via Garmin, Fitbit, Strava, whatever send it on over so I can update your results.
