Im looking at clocks for the 14.

I was interested in GPS types but one of
my regular runs is a 4 mile long tunnel,
60m under the river, 10m under the bedrock.

It has 4 speed camera's and my GPS isnt a
lot of use down there.

(although the GSX's open pipes in 2nd gear at 80kph
sound like the gates of Hell have been opened!)
