I ran the Southampton 10km on Sunday and around the 3-4Km mark there is a huge bridge you run up, over and down and then turn around and go back over it again. I looked at the elevation data on my FR235 (v4.1) after the race and expected to see two symmetrical humps but there was only one. The bridge is around 800m long (1.6km round trip) so should have produced some clear data. Any ideas?
