Here is a snapshot of the data from my Suunto GPS during the St Moritz marathon. There is some interferance at around the 25min mark. I don't think we did 108km/h. There seems to be some problems between the connection of my watch and the computer because here is the correct information:
Total time- 57:31
Distance- 41.65km
Avg speed- 43.5kph
Max speed 74.4kph
Start alt- 1781m
Finish alt- 1633m
But you can see for most of the graph the main group was sitting mostly between 35kph-55kph.
