Sounds like it could be retro friendly.
54km cycling event starting from Dalkeith., plus 1 information control.
Mostly off-road event using the network of paths, tracks and disused railways througout East Lothian.
MTB or cyclo-cross style tyres recommended due to the terrain although may be largely passable on road tyres (weather dependant).
