I find 7,700 cumulative climb.<BR/>However, my altimeter (Nike) said 4,385.

My Geko 301 usually gives pretty accurate elevation data as well, but I have never used it on a bike. I have heard some of those fancier wrist-watch based altimeters are extremely accurate.<BR/><BR/>I went back and looked at your map more closely and I do see the thin black line.

I've used a Garmin on hikes in that area and it has been pretty accurate, but I generally don't go over any rivers, and, as far as I'm concerned, there are no cliffs.Chamhttps://www.blogger.com/profile/06353036103471800904noreply@blogger.comtag:blogger.com,1999:blog-15637711.post-1143395735006179512006-03-26T12:55:00.000-05:002006-03-26T12:55:00.000-05:00Ah yes, Your GPS uses TOPO database to determine e...Ah yes, Your GPS uses TOPO database to determine elev gain? Here in the western US TOPO can be wildly inaccurate. One route I have, TOPO says 16,000. In reality, 6500 according to real altimeters. TOPO doesn't account for cuts & fills in the road or the fact that you're not crossing the river by boat... your on the bridge...or that you're not on the cliff you just went by.
