Here's a link to the run. The short out-and-back at the top is the missing section of Testsmine Loop. The straight line is where I paused the watch while we drove between trailheads.
Without having a GPS track to come back to, I never would have noticed this and would have happily continued assuming it was covered. Admittedly that would have been an easier way to go, but I'm glad to have a backup and know for sure that I did the entire challenge. I did this challenge in honour of my mom, and I needed it to be done right. (Fittingly, the yellow challenge sign for this loop referred to GPS use in the park. We had a good laugh about that.)
Speaking of GPS, I did a post a few years ago on GPS tracks being able to be modified, but never really addressed the accuracy of the tracks to begin with. It is always interesting to see the differences in our stats when Derrick and I run the exact same route. He has a newer model of Suunto Ambit, presumably with a more sensitive receiver, and he routinely gets distances that are longer than mine, especially on single-track trails that typically wind around a lot.
Derrick's tracks versus mine for days 1 and 3, where we ran every single step the same. Very different stats for both distance and altitude. (Click images to enlarge.)

|For comparison, here is the SPOT track for Day 3. Not very useful under such a thick tree cover and only trying to get a read every 10 minutes!|
