While I was flying next to Robert Reisinger I was flying just behind Jonny Durand, Jr. You can find the IGC file file here (Davis) and here (Jonny). I flew with him for 12.5 km until we hit the strong thermal.

From 14:00:22 to 14:09:35 Jonny flew at 39 mph, for 13.5 km and had an L/D of 40.6. I flew at 36 mph for 12.5 km and had an L/D of 45.2.
