A few times during the ride the unit lost GPS signal, but as I&#8217;ve had this happen on other rides without issue I didn&#8217;t pay it much attention. Unfortunately, it looks like this time the data really went odd. After poking with the data and attempting to correct it in <a href=\"http:\/\/www.montebellosoftware.com\/\">Ascent<\/a> I downloaded <a href=\"http:\/\/fitfilerepairtool.info\/\">Fit File Repair Tool<\/a> to see what it could tell me.<\/p>\n<p>As shown in the screenshot above (click to embiggen), roughly 15.52 miles in, at\u00a0<a href=\"https:\/\/maps.google.com\/maps?q=44.2119%C2%B0N+86.1295%C2%B0W&amp;ie=UTF8&amp;ll=44.212049,-86.097279&amp;spn=0.042141,0.104628&amp;hnear=0x881e84fd85e392db:0x70a236c06364231c,44.2119%C2%B0N+86.1295%C2%B0W&amp;gl=us&amp;t=h&amp;z=14\">44.2119\u00b0N 86.1295\u00b0W<\/a>,\u00a0just beyond the Steinberg Road crossing in Road Monkey during my first lap (map <a href=\"http:\/\/lumberjack100.com\/wp-content\/uploads\/2013\/02\/Lumberjack-course-map.pdf\">here<\/a>), the recorded time suddenly jumped from June 15, 2013 to October 19, 2019. This explains the strange duration I&#8217;d been seeing in analysis software, with everything from Ascent and <a href=\"http:\/\/www.strava.com\">Strava <\/a>both reporting an elapsed time of around\u00a055619:03:11, the length of a ride which I don&#8217;t quite think the Edge 500&#8217;s battery would endure, but which matches the 6-some year offset. Weirdly, Garmin Connect doesn&#8217;t show the issue (<a href=\"http:\/\/connect.garmin.com\/activity\/329424918\">link<\/a>), almost as if they filter out this problem.<\/p>\n<p>When this issue occurred my Garmin was running firmware v3.00, something which I was hesitant to change soon before the race. Since the changelog to v3.20 only <a href=\"http:\/\/www8.garmin.com\/support\/download_details.jsp?id=4715\">lists two minor changes\u00a0which aren&#8217;t useful for me<\/a> (power meter serial number display and a change to support manufacturing) I didn&#8217;t see a good reason to rush to upgrade. It&#8217;d also worked otherwise well for long rides, so I didn&#8217;t anticipate any problems. I upgraded the unit to v3.20 today and I&#8217;ll see if similar problems arise, but I can&#8217;t imagine I&#8217;ll be doing that length of ride any time soon, so it&#8217;ll be hard to get an equivalent test.<\/p>\n<p>If any of you wish to review this damaged FIT file from Lumberjack 100 it can be found <a href=\"https:\/\/nuxx.net\/files\/gps\/svigneau_2013_lumberjack100.fit\">here<\/a>: <a href=\"https:\/\/nuxx.net\/files\/gps\/svigneau_2013_lumberjack100.fit\">svigneau_2013_lumberjack100.fit<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After getting back home from completing Lumberjack 100 I was excited to review the logged data from my Garmin Edge 500 bike computer.
