Monday Report


Well it’s Monday and it has been a busy week-end, on and off the trail.  I ran the Tolt pipeline trail as planned Saturday but I haven’t had time to download the GPS track from the Foretrex.  The navigation device did come handy during the trail run.  First to find the actual entrance to the trail at the drop off point in Duval.   I almost ran by I about ¼ mile into the start of the run.  The “off track” screen indicated I was running away from it (I though) because the indicator mileage was increasing as I was adding mileage to the run … later I found that the mileage from waypoint continued to increase throughout the run so I have yet to figure out how to interpret that data.  However the “off track” indicator is accurate in indicating how far off the GPS route you are off.  I could switch to the Map screen where it showed my location and direction relative to North and the route waypoints.  I could navigate to the waypoints ensuring my position stayed on the route.  Another great feature I found was the elevation screen, which I could zoom in and out and would show the relative elevation … So that for example I could check if another uphill was around the corner of this uphill …

Things I did not see on the Google Earth fly by was that there was no bridge to cross the Sammamish river when the Pipeline Trail crosses the Sammamish River trail … Duh!  Fortunately 145th had a bridge about ¼ mile south of my position … My Iphone was still handy in deciding whether to go North or South to find a bridge.  Had I went north it was a detour of several miles to 175Th.  I rejoined the trail following the map on my phone then reverted to GPS nav.  Well in this case I was following the trail but that sound pretty fancy when I write that in here.  The 405 waypoint (where I had to exit off the trail to find the overpass and re-join the trail westbound) came up on the GPS map.  I followed the map on screen for turns which lead me to the overpass fine however I ran by the entrance again.  I could see on the map I was about to pass it, then could see my tracks leading away from the route so I knew I needed to head back.  I looked for a trail entrance but could see only street signs.  I headed west on the street that seem to be where the map said I was offtrack.  After a visual scan I did see the trail entrance about 50 feet down to the left.

I hope to find some time to download the tracks from the GPS device and transfer the tracks to Google Earth and see if I can create a movie of my run … More to come on that.  Overall I am please with the purchase so far.  On the cons I think Garmin lacks support for the novice user (I had to research “how to’s” off the internet to figure out how to create a map and transfer it to the GPS.  The pace information that the salesman at REI told me was supported by Foretrex is non-existent (or haven’t figured where that feature is).  The speed data and average travel speeds are given in mph so it’s a little cumbersome to me as a runner since I am used to min/mile.  That is a very nice feature of RunKeeper that helps me when I run long distance events.  I can learn the conversion in my head from mph to min/ile for common time to overcome.
