I did 16 miles a fortnight ago, including one dirty b*****d of a climb at Camperdown Park.
I'm trying to build myself up to doing the full 26 miles of the Dundee Green Circular again. The first (and last) time I did it, it was very much on a whim: I headed off and just kept going.
Took me a little under 3 hours, including a 10 minute lay-off at Camperdown, which I was delighted with.
