I saved the route, but I haven't figured out how to look at it again. I didn't turn off the navigating when I turned it off at the end of the ride, so when I turned it on again it added a point at home. I don't know how to get rid of that. I'll have to dig out the manual.
I showed 19.4 miles and 2100 feet of elevation gain. I could very clearly see the three big hills...what were the % grade on them? I'd like to get a sense of what a 10% vs 15% hill feels like.
If your Garmin is like my Garmin, I don't think you can delete individual data points....which really stinks....b/c you can't correct obvious errors such as this.
Here's a pdf file (attached...I hope it works) with some printed screenshots from my TrainingCenter (Garmin desktop app). Note the highest elevation point (1925 ft at mile 15, which was on Tower Road). The highest % grade I registered was 16%, which - predictably - was at mile 4.6, which was at the end of Fox Tower (the "wall"). A few sections on that road ranged from 14 to 16%.
